## AI IN RETAIL: AGENTIC OPERATIONS & COMMERCE ​Die Expert Group „AI in Retail“ bietet Entscheidungsträger:innen aus Handel, Konsumgüterbranche und Technologie eine Plattform für regelmäßigen Austausch – vom Use Case zum Business Case. ​Unser zweites Treffen steht im Zeichen von „Agentic AI im Handel“ – und wir beleuchten das Thema aus zwei Perspektiven: Wie setzt ihr selbst KI-Agenten in euren Prozessen ein, um operative Abläufe end-to-end zu übernehmen und Kosten zu senken? Und was bedeutet es, wenn Agenten bald auch von außen auf euer Unternehmen zugreifen, einkaufen oder euch als Kanal umgehen? Konkret, praxisnah und interaktiv – mit Impulsen, Workshops und dem Austausch mit Branchenkolleg:innen und führenden Expert:innen. ​Lösungen für heute. Strategien für morgen. ​Bitte geben Sie uns bis zum 25.06. Bescheid, ob Sie dabei sein werden.

**The AWS Women’s User Group Berlin** is thrilled to invite you to our upcoming meetup sponsored by Storm Reply focused on **Building production-ready AI agents for real-world impact.** Join us for a deep dive into how to build, observe, and evaluate AI agents at scale. You’ll also see how these ideas come to life in a real-world climate-smart agriculture solution that turns weather forecasts into actionable field guidance. Whether you’re building agentic systems today or planning what comes next, this meetup will give you practical insights into making AI agents work in production. **Speaker Info** **Keynote Talk** **Speaker:** Tetiana Senna **Position:** Team Lead / Senior Project Manager, Storm Reply **Talk Title:** Trust, but Verify: Observability and Evaluations for AWS Agents **Abstract:** Getting an AI agent to work in a demo is easy. Knowing whether it still works in production - after the next prompt change, the next model upgrade, the next edge case - is the hard part. Unit tests don't cover non-deterministic behavior, and manually reviewing a handful of runs doesn't scale. This talk walks through the two practices that close that gap: observability (understanding what actually happened inside your agent) and evaluation (deciding whether the outcome was any good). We'll dig into Amazon Bedrock AgentCore's Observability and Evaluations capabilities, compare the proven evaluation approaches - built-in LLM-as-a-Judge evaluators for automatic quality monitoring, and custom evaluators for business-specific correctness checks - with a candid look at what each one is good for, where it falls short, and what it costs to run at scale. We'll also take a close look at AgentCore Optimization, AWS's newly previewed feature in this space. **Applied Agentic AI Talk** **Speakers:** **Vidhu Mitra Malladi:** Senior Software Engineer, Yara Digital Farming **Chamika Hasanthi:** Senior Software Engineer, Yara Digital Farming **Talk Title:** Weather Risk Intelligence Agent for farmers & Agronomist Abstract: Unpredictable weather events — heavy rainfall, drought, frost, and heatwaves pose significant risk to crop yield and fertilizer efficiency. While forecast data is widely available, it is rarely translated into timely; field-level guidance farmers can act upon. Using AWS AgentCore framework and AI capabilities, we can turn weather predictions into clear agronomic actions, supporting climate-smart agriculture at scale. **You'l learn:** * Implementation of the solution using AWS Agent Core framework * Architecture of the project. 🗓️ **Event Details:** \- Date: Tuesday\, June 30th \- Venue: Storm Reply GmbH\, [address](https://www.google.com/maps/place/Storm+Reply+GmbH/@52.5012692,13.368852,17z/data=!3m1!4b1!4m6!3m5!1s0x47a851119af460c5:0x35e34ba578e8b1ec!8m2!3d52.5012692!4d13.368852!16s%2Fg%2F11gg9298pv?entry=ttu&g_ep=EgoyMDI2MDUxNy4wIKXMDSoASAFQAw%3D%3D) \- Time: 06:00 PM \- 9:00 PM Doors open at 6:00 PM Food & drinks will be provided. 📋 **Program Schedule:** **18:00** \- Registration and Welcome Networking **18:20** \- AWS Women's User Group Welcome **18:30** \- "Trust\, but Verify: Observability and Evaluations for AWS Agents" **Speaker:** Tetiana Senna, Team Lead / Senior Project Manager, Storm Reply A practical session for anyone working with AI agents on AWS who wants the confidence to put them in front of real users.

Farmworkers and small farmers sued the university behind the technology, arguing they were being forced to fund their own replacement. They lost. But the questions they raised never went away. Today, researchers are using AI, robotics and gene editing to create tomatoes that can be pollinated by robots, crops designed for automated production systems, and even new traits engineered for consumer preferences. AI is having an impact on agriculture, food production, and labour, often with public money, rarely with public input. Sounds familiar? ​**What to expect** ​A 90-minute interactive evening: * ​**Opening talk** connecting the tomato harvester story to today's AI developments * ​**Live audience polling** * ​Conversation with **Ildi Carlisle-Cummins** (California Institute for Rural Studies): storyteller, oral historian, and director of the Cal Ag Roots project, one of the organisations that grew out of the original lawsuit * ​Open audience **discussion** * ​**Informal networking** to close ​**What you'll take away** ​A sharper way to think about who controls the technologies influencing our food, our work, and our world, and what citizens can actually do when change feels inevitable. If the phrase "square tomato" sounds too strange to be true, you're not alone. Even the TV detective [Mr. Monk couldn't believe his eyes](https://youtu.be/VtO-97pl7cA?is=VnMxtacAwL1IChub)! **​Free to attend, free of jargon, no expertise required.** **Just bring your curiosity.** ​*Hosted by [Save Our Seeds](http://www.saveourseeds.org/?utm_source=luma) and [Human-Future-Hub](https://humanfuturehub.org/?utm_source=luma) Berlin* Tea, coffee, water, beer, wine, and pizza will be available throughout the evening.

This will be the first meetup of the group. A relaxed evening for people interested in bug bounty hunting, web security, AppSec and vulnerability research. The main goal is to meet like-minded people, talk about bugs, tools, targets, methodology, reports, interesting findings and whatever else comes up around security research. Since it is the first event, we can also spend a bit of time discussing how future meetups should be structured: casual chats, hacking sessions, short talks, tool sharing, report discussions or presentations. As soon as at least **3 people join**, I will look for a suitable location. The first meetup will probably be in a **café, bar or restaurant**. If there is enough interest in presentations, I can also look into booking a room with a **TV or projector** for future events. No preparation needed. Please keep everything legal and authorized.

Most brands track whether they appear in ChatGPT, Gemini, and AI Overviews. But mentions and citations only tell half the story. In this session, Raoul Schreck, our CEO at Buzzmatic will show you how to systematically analyze what AI actually says about your brand: which attributes it assigns to you, which USPs it credits to your competitors, and where your communicative blind spots are. Using a real client case and a concrete 4-layer framework, you’ll learn how to move beyond visibility tracking and uncover the narratives AI systems are building around your brand — and what to do about them the next morning. Book your ticket now to secure your spot at the Rise & Rank SEO and AI breakfast!

The course will start this Saturday at 10am. It will be in studio R at CCB studios. [https://maps.app.goo.gl/rFovxE7eG7HV6uB46](https://maps.app.goo.gl/rFovxE7eG7HV6uB46). Buzz for CCB studios and then walk through to the second courtyard. We will try to start right around 10. There will be tea available. Please dress in comfortable clothes, maybe wearing a few layers. Theres some blankets, yoga mats, cushions and chairs in the room that you can use. The plan will be for us to do some small discussions at the top and then start discussing theory before doing some meditations of increasing length and then closing with some time for Q & A. We will take a short break in the middle as well. The plan is to go from 10-12 roughly but we may end a little closer to 11:30 depending. This week will function primarily as a simple introduction to meditation and some topics in the space but we will also discuss what the Jhanas are. Looking forward! Any questions please just message me.

This talk walks through a practical demo of automating the full SRE lifecycle: from incident investigation to deployment validation, using Grafana MCP and the GitLab Agent Platform, and where humans still need to stay in the loop. *Serhii Vasylenko* **The Pipeline Was Green — AI Agents and CI Trust** We’ve spent years building CI/CD pipelines that tell us when code is "technically correct," but are they capable of telling an autonomous AI agent if a change is safe to apply? This talk explores a real-world incident where an AI-powered automation -- pairing Renovate with Claude Code -- successfully executed a "green" pipeline that broke a critical QA cluster for three days, how the team reacted, and how we evolved our vision toward the future of human-agentic collaboration with code. *Frithjof Hoffmann* **Managing Uninvited Guests: Securing Open Source Dependencies** Open source software is the ultimate neighborhood party, but what happens when an uninvited guest slips through the door? This talk digs into the messy reality of dependency hell and its role in software supply chain security: from typosquatting attacks to maintainer account takeovers, and the abandoned projects with known CVEs quietly living in your codebase rent-free.

📆 Agenda * 19:00 Welcome to the PUB (Python Users Berlin) – setting up * 19:15 Main talk * 20:00 Lightning talks * 20:30 Social gathering 🎙 Main talk by [Sam Bail](https://www.meetup.com/de-DE/members/57634242/): PySpark PySpark is a powerful library that brings Apache Spark’s distributed computing capabilities to Python, making it a key tool for processing large-scale data efficiently. In this talk, data engineer and analyst Sam Bail provides a structured and hands-on introduction to PySpark, starting with an overview of Apache Spark, its architecture, and its ecosystem, such as Databricks. Learn about Spark’s core concepts, such as the DataFrame API, transformations, lazy evaluations, and actions, before setting up a lab environment and working with a real dataset. Plus, gain insights into how PySpark fits into a broader data engineering ecosystem and best practices on running PySpark in a production environment. 👩‍💻 About [Sam Bail](https://www.meetup.com/de-DE/members/57634242/) Data engineer and engineering leader with 10+ years building platforms and teams across healthcare, marketplaces, and data infrastructure at NYC tech startups.

**Practical Curiosity: Learning from Everyday Data** How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice. Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look. In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it. **About Our Speaker:** [Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
