Maintainable Frontends for Symfony & Why every CMS needs MCP
Hello fellow Symfonians,
we are thrilled to announce the next user group meeting of the year, featuring two insightful talks that you **won't want to miss**!
This time we are hosted by c-base (Rungestrasse 20
10179 Berlin).
Come by and enjoy an evening of learning, networking, and socializing with fellow Symfony and PHP developers.
**Agenda:**
18:30: Doors open
19:00: Welcome and Introduction
19:20: **Talk 1: "Maintainable Frontends for Symfony" by Daniela Berger**
19:50: Break & Snack
20:00: **Talk 2: "Why every CMS needs MCP" by Roland Golla**
20:40: Socializing
**Talk Details:**
**Talk 1: "Maintainable Frontends for Symfony" by Daniela Berger**
In many web projects we find more backend devs than frontend devs, sometimes significantly so.
This often leads to devs with little frontend experience being asked to do frontend development anyway, and they often end up shaping their frontends in ways that will make their lives unnecessarily hard.
One common result are frontends that are functionally unmaintainable because each change - whether it is a new feature or a bugfix - requires implementing an exception to existing code, thus making the code increasingly and unnecessarily complex.
This is especially upsetting because with a bit of experience it is possible to implement light-weight frontend components with equally elegant CSS and JavaScript that are easy to extend and to adapt to new requirements without digging oneself into a deeper hole with each PR.
And since Symfony is making frontend development steadily more accessible to backend devs with Symfony US / Stimulus, this is a good time to take a closer look at \*how\* to structure these frontends.
This talk aims to a) introduce core frontend concepts that backend devs might not be aware of, b) show best frontend practices both on the code level and on the architecture level, c) show a few common mistakes that can be found in inexpertly implemented frontends, and c) introduce tools that will make consistent frontend development easier.
**Talk 2: "Why every CMS needs MCP" by Roland Golla**
Your content team already works in ChatGPT, Claude, and Gemini. Yet the content still lands in the CMS backend manually, clumsily, slowly. MCP changes that. One sentence in chat becomes a published article. No copy pasting, no formatting, no clicking.
And the content ranks. On Google, on ChatGPT, on Perplexity, on whatever comes next. Good content written by AI directly into the CMS goes live faster and gets found.
I show you the MCP plugin for Sulu CMS: open source, built on Symfony, ready to deploy. But this is not about implementation. It is about the three questions every content team must ask: Why does every website need MCP? What does good AI content look like? And why is conversational content management better than anything you click together in a backend?
MCP makes content creation as easy as chat. If you can write, you can publish. No CMS training, no workflow, no waiting.
Live on stage: a complete workflow from idea in chat to published article in Sulu CMS. Everything open source on GitHub.
Don't miss these insightful talks, engaging discussions, and networking opportunities. We can't wait to see you at the **April Symfony User Group**!"
If you have any questions or accessibility requirements, please reach out to us. Also, if your company wants to be the next host for the User Group, just let us know!
German Sprachcafé at Denizen! levels A2 - C1!
**We’ll now be meeting twice a week at Denizen House (Köpenicker Str. 40, 10179 Berlin), on** **Mondays and Wednesdays!**
* **Mondays:** **levels A1 to B2**
* **Wednesdays:** **levels A2 to C1**
**We work with dedicated materials tailored to each level, so everyone will have a place to practice and improve.**
**Event schedule**
* **18:00 – 18:30** **Arrival and registration**
* **18:30 – 19:50** **Sprachcafé**
* **19:50 – 20:00** **End and clean up**
**Please be aware that the moderated event starts at** **18:30. Before this time, we are busy setting up the space. Registrations usually take place around** **18:15 / 18:20. Participants are kindly asked** **not to arrive too far in advance** **at the house.**
**If someone arrives much earlier, Denizen may ask them to pay either for a drink (consumption) or for a** **day pass, as the space is a co-working environment during the day.** **Please remember, our event is only happening from 18:00 to 20:00**
**How the Sprachcafé works**
**We use different materials to help participants gain confidence in German. Together with whiteboards and our volunteers, the Sprachcafé is based on** **interactive conversations** **in small groups.**
**Participation fee**
**The Sprachcafé has a** **participation fee of 5 €, which helps cover organizational costs and** **includes one soft drink for free.**
**Tickets can be purchased directly on the day of the event, card and cash payments are accepted.**
**As the Sprachcafé has become very popular, we now need to** **limit the number of participants. Please understand this measure; it ensures that everyone has a comfortable space to practice.**
**We kindly ask you to be** **rücksichtsvoll** **and only RSVP “Yes” if you are certain you can attend.**
**If your plans change at the last minute, please update your RSVP so someone on the waiting list can take your spot.**
**Getting your ticket early can help secure your place.**
**Please note**
**Our event will begin** **promptly** **at the scheduled start time.**
**If you arrive late, we cannot guarantee your participation, even if you have a ticket or have RSVP’d. We encourage all guests to arrive on time to ensure a smooth and enjoyable experience for everyone. Thank you for your understanding and cooperation.**
**About Denizen**
**Denizen is a new-style co-working space focused on being an integral part of local communities. Located on the ground floor of the historic Eiswerk on Köpenicker Straße in Kreuzberg, Denizen House is a communal place providing work, refreshment, and recreational facilities throughout the day. Think of it as a living room for the neighborhood.**

Building in Data: From AI Agents to Career Shifts | Data Engineering Meetup
Dear data-loving community, we’re excited to invite you to our next Meetup! This time in collaboration with [Spiced Academy](https://www.spiced-academy.com/en), who will be hosting us at their space.
Join us on April 23 in Berlin and bring all your questions! :)
**Tom Kaltofen: *"Building Deterministic Context Layers for AI Agents"***
[Tom Kaltofen](https://www.linkedin.com/in/tomkaltofen/) is an Engineer at [DHL Data & AI](https://www.linkedin.com/company/dhl-data-ai/) and a Creator at [mloda.ai.](http://mloda.ai.)
About his keynote:
"Data access and reuse are still unsolved, and AI agents are making it worse. This talk goes deeper into that problem: AI agents depend on reliable context (data, features, intermediate state) to make correct decisions. In practice, this context is tied to specific pipelines or infrastructure, leading to brittle systems when moving from prototype to production.
I'll show how a plugin-based approach lets teams build deterministic context layers: separating what you compute from how you compute it, so the same feature definitions work on a laptop and in production.
The talk includes a live demo where an AI agent discovers and queries data features programmatically. "
**Behnaz Derakhshani: *"What If I Started Today? Rethinking Career Switching in the AI Era"***
[Behnaz Derakhshani](https://www.linkedin.com/in/behnaz-derakhshani-63342775/) works as a Data Engineer at [Diconium](https://diconium.com). She shares her personal career shift from finance to data engineering, including the unfiltered challenges and lessons along the way.
About her keynote:
"Eight years ago, there was no AI to debug my logic, just documentation and Stack Overflow. Now as a Data Engineer, I’m breaking down the lessons learned from my finance to tech transition and why AI makes this the most exciting (and accessible) time to pivot."

**Kaputt: A Large-Scale Dataset for Visual Defect Detection**
We present a novel large-scale dataset for defect detection in a logistics setting. Recent work on industrial anomaly detection has primarily focused on manufacturing scenarios with highly controlled poses and a limited number of object categories. Existing benchmarks like MVTec-AD (Bergmann et al., 2021) and VisA (Zou et al., 2022) have reached saturation, with state-of-the-art methods achieving up to 99.9% AUROC scores. In contrast to manufacturing, anomaly detection in retail logistics faces new challenges, particularly in the diversity and variability of object pose and appearance. Leading anomaly detection methods fall short when applied to this new setting.
To bridge this gap, we introduce a new benchmark that overcomes the current limitations of existing datasets. With over 230,000 images (and more than 29,000 defective instances), it is 40 times larger than MVTec and contains more than 48,000 distinct objects. To validate the difficulty of the problem, we conduct an extensive evaluation of multiple state-of-the-art anomaly detection methods, demonstrating that they do not surpass 56.96% AUROC on our dataset. Further qualitative analysis confirms that existing methods struggle to leverage normal samples under heavy pose and appearance variation. With our large-scale dataset, we set a new benchmark and encourage future research towards solving this challenging problem in retail logistics anomaly detection. The dataset is available for download under [https://www.kaputt-dataset.com](https://www.kaputt-dataset.com).

**Data Foundations for Vision-Language-Action Models**
Model architectures get the papers, but data decides whether robots actually work. This talk introduces VLAs from a data-centric perspective: what makes robot datasets fundamentally different from image classification or video understanding, how the field is organizing its data (Open X-Embodiment, LeRobot, RLDS), and what evaluation benchmarks actually measure. We'll examine the unique challenges such as temporal structure, proprioceptive signals, and heterogeneity in embodiment, and discuss why addressing them matters more than the next architectural innovation.
*About the Speaker*
[Harpreet Sahota](https://www.linkedin.com/in/harpreetsahota204/) is a hacker-in-residence and machine learning engineer with a passion for deep learning and generative AI. He’s got a deep interest in VLMs, Visual Agents, Document AI, and Physical AI.
**Most AI Agents Are Broken. Let’s Fix That**
AI agents are having a moment, but most of them are little more than fragile prototypes that break under pressure. Together, we’ll explore why so many agentic systems fail in practice, and how to fix that with real engineering principles. In this talk, you’ll learn how to build agents that are modular, observable, and ready for production. If you’re tired of shiny agent demos that don't deliver, this talk is your blueprint for building agents that actually work.
*About the Speaker*
[Bilge Yücel](https://www.linkedin.com/in/bilge-yucel/) is a Senior Developer Relations Engineer at deepset, helping developers build agentic AI apps with Haystack. Passionate about AI, she makes complex concepts approachable through hands-on tutorials, both online and at real-life events.
**Operationalizing Computer Vision for Overhead Lines: Beyond the Demo**
At first glance, visual inspection of high-voltage power lines seems straightforward: collect imagery, run one or two AI models, and report the findings. In practice, moving beyond a proof of concept reveals a range of issues that can make or break a campaign. Common concerns include data quality and coverage, scarcity of the most relevant cases and abundance everywhere else, variations in pylon geometry and asset types across regions, calibration and GIS alignment challenges, and a long tail of edge cases that emerge in real-world operations.
This talk introduces Siemens Energy’s end-to-end overhead line inspection solution and shares key learnings from inspecting more than 10,000 km of power lines for real customers across several continents. We will show how raw 2D/3D data is transformed into structured information, delivering insights into asset inventory as well as defects, and supporting maintenance and planning decisions for critical infrastructure. The focus is on the combination of algorithmic building blocks and scalable processing, designed for robustness and consistency at scale, where even low error rates can become operationally significant.

Programmiercafé
A space for working on projects & learning new stuff together. 💻☕️
Please RSVP if you intend to join, as we have limited space. 😊
Humboldthain Park Volley ☀️ 🏐 🌴
Join us for outdoor grass volleyball in **Humboldthain** park!
We play with two nets. The "chill court" is for mixed-level play with 3v3 up to 5v5. The "competitive court" is for higher-level 2v2 play with beach rules. This week, complete beginners are welcome on the chill court.
Be sure to wear suitable sports clothing and perhaps bring a drink.
**Location**: This week, we play in the big clearing of **Volkspark Humboldthain**. We are NOT playing in Hasenheide as usual. Updates will be posted in the WhatsApp group, which you can join via [https://tinyurl.com/ParkVolley](https://tinyurl.com/ParkVolley)
**Facilities**: There are no facilities such as changing rooms and showers in the park. A nearby public toilet is also available, but it might be closed, dirty, or not have toilet paper. There is also a toilet in the nearby Kaufland.
**RSVP**: Put yourself on the waitlist, even if other people are already on there. The waitlist is not chronological, so even if there are 30 people on there, you still have a chance! If you get a spot, you will be moved to the attending list and notified by Meetup. This is a free event with limited space. **If you can't make it, promptly update your RSVP to NO** so others can take your place. If you do not show up or cancel last minute, you will be marked as a no-show, reducing your chances of getting off the waitlist in the future.
**Payment:** This event is free, but you are invited to make a 2 EUR donation towards equipment.
**Attending**: Do not join if you have an infectious disease. You need to be on the attendee list to attend; **being on the waitlist is not sufficient**. Do not bring friends that are not on the attendee list. **Showing up without having a valid RSVP will get you banned**.
**Safety**: Mind the terrain. The grass might be uneven and contain items such as bottle caps. It is not suitable for diving or playing like on a beach. Be careful not to twist your ankle. Keep an eye on your belongings since we are in a public park. We do *not* have a full first aid kit available. Please inform the organizer of any medical conditions that might require attention during the event.
Some things you *might* want to bring:
\* Drink
\* Snacks
\* Insect spray
\* Sunscreen
\* Toilet paper, if you wish to use the public toilet

Kumustahan #2 (Berlin Edition)
I think it will be sunny again this weekend, if you are free, let us meet at Boxhagener Platz this coming Saturday, April 25, at 1:30-3:30 pm. Organizing a community is not easy to do, maybe this could be one topic of conversation! Taralets!
**Filipino Vocabulary:**
**Kumustahan** refers to a gathering or activity where people greet each other and communicate, often sharing stories and news. It is derived from the Filipino phrase “*Kumusta?"*, which means “How are you?” in English.
**Taralets** is a blend of the Tagalog word “tara (meaning "let's go") and the English phrase "let's go.” Just like saying, "*Los geht’s”* in German!

What If Your AI Could Be a Team? - Chad Green
**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you.
The building address is 4450 Bridge Park
The entrance is 6620 Mooney St, Suite 400
You will need to scan your ID at the door to get a visitor badge.
**Abstract**
GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise.
We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration.
Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team.

Shut Up & Write!® East Side Columbus
Join us for an hour of writing! We’ve discovered that it’s strikingly helpful to write with other writers. See if it’s true for you at 7:00pm on Wednesday, April 22 at Streetlight Guild.
Be it a book, blog, script, essay, dissertation, resume, melody, poem or just plain work stuff, you are invited to write it with us. No one will see what you've written or give you unsolicited advice. Instead of just thinking about writing, come and get some real writing done.
**SCHEDULE:**
6:45ish - Quick introductions
7:00 - Timer starts: write for 1 hour
8:00 - The End
**OPTIONAL SOCIALIZING** happens before and after the writing hour. Writing is very solitary. Connecting (and sometimes even commiserating) with other writers is a cool thing.
**BEING LATE IS OKAY:** just show up and get settled! If you were on time, please be willing to make room for the friendly latecomer.
Happy writing & I look forward to seeing you at Streetlight Guild!
**WHAT SHOULD I BRING?**
Whatever you need to be able to write! You're welcome to bring earplugs/headphones if noise will bother you!
**OTHER IMPORTANT DETAILS:**
* **RSVP:** Please RSVP by 6:00pm the evening of the meeting. This helps me know how many to expect, and if we'll need additional space!
* **COVID:** While masks are not required, please be mindful of the other writers around you and their comfort levels.
* **WIFI/OUTLETS:** Outlets are limited, so please ensure your devices are charged when you come! But Streetlight Guild does have free WiFi! Yay!
* **PARKING:** There is free public parking at Streetlight Guild.
Columbus Arduino Raspberry Pi Enthusiasts (CARPE) (Check Location)
Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration!
This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired.
**New to electronics or curious about tinkering?**
You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building.
While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.
