**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.

📆 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. I teach data engineering courses on LinkedIn Learning and O’Reilly, focused on making complex topics accessible to everyone. I also founded Bright Nights Social, an alcohol-free nightlife community that’s produced 100+ events across NYC. You’ll probably find me on a dance floor or running around Berlin this summer (training for the Berlin marathon). 📚 Resources * [Apache Spark](https://spark.apache.org/) * [PySpark](https://spark.apache.org/docs/latest/api/python/index.html) * [PySpark DataFrame API](https://spark.apache.org/docs/latest/api/python/getting_started/quickstart_df.html) ⚡️ Lightning talks We would like you to give a lightning talk (shorter than 10 minutes) about what you are doing with Python. 📍This will be a face-to-face meeting.

Nice! You are looking for real long time friendship! You might have already lived in Berlin or other big cities and experienced the "Anonymous" culture for a while. Meeting random people over and over and never see the same person again! In order to find "Real Long Term Friendship" in Berlin, do as follows: * You should not care how many people are joining this meetup. You RVSP. Even if only one person is joining. Because if everyone are waiting for everyone else to RVSP, nobody joins and nobody finds a new friend. * You do not care how many people of the opposite sex are joining. You are looking for friends. Finding the best romantic partner in the world, while avoiding not very attractive others, can be your other goal, for another time. Here we are looking for Friends. Real ones. * You are going to risk a very precious property of yours: Your time! Yes, there are thousands of opportunities in Berlin, there might be a rock concert for free, a birthday party you might miss, an important person might call you and invite you spontaneously, but you never find new friends until you decide to risk your time and meet people anyway. "I will check my calendar and get back to you" also does not work. Commit your time and spend it. Trust me, you won't go bankrupt ;-) * You are ready to use your phone as a real phone! You might have been using your phone as a tablet to visit Instagram and Facebook and watch movies. But if you want to find friends, you must know that people might take your phone number and give you theirs. That means they will Call you! And you have to pick up the phone and answer it. If you want to find new friends, you must be ready to do something really hard for the first time after years: Call people first, and if they called you: Answer your phone! * You are going to meet some people twice! That's the point of friendship. We already can experience random encounters with random people in random places one at a time. But that is not called friendship. If you want friends, you must be ready to meet the same person more than once. If you agree with above, RVSP and COME! You will meet other people who think the same way. P.S: Now that you've read all the way down to here, I suggest you [watch this animation](https://player.vimeo.com/video/547249272?h=22f3dd0f6f).

***An Evening of Authentic Relating, Attunement and Connection*** What becomes possible when authenticity and belonging meet? This first Authentic Belonging Circle is an invitation to slow down, arrive more fully in yourself, and explore genuine connection with others. Together we'll create a space rooted in play, supported by clear boundaries, and open to depth. During the evening, we'll explore a blend of Authentic Relating games, partner exercises, embodied practices, and Circling. Some moments may be light and playful, others more intimate and reflective. You are invited to: • connect with yourself and others in new ways • practice deep listening and authentic expression • explore what it feels like to stay connected to yourself while relating • cultivate greater presence, attunement, and belonging No previous experience is needed. Whether you're new to these practices or already familiar with them, you're warmly welcome. The circle is held by Manuela, a systemic coach and facilitator trained in Authentic Relating, Heart IQ, TEPP, and other relational and embodiment-based approaches.

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.

**Creative Session for Song-Writers & Writers to connect, share & grow. Together.** We create a safe and inspiring space guided by our DNA.

On the 1st of July we will host the next iteration of our monthly Audio Developer Meetup where **Peggy Sylopp** from [sinceare](https://www.sinceare.com/) will be presenting her work on personalization approaches for hearables, and **Vlad Litvinenko** will demo 'Spotykach', a looping playground. See below for details! As always, there will be a chance to network over drinks and pizza. Anyone interested in Audio development is welcome! Doors open at 18:00, talks start at 18:15. Please note: Attendance is **strictly limited** to people who have RSVP'd. Talk details: **Can users train their own audio system?** \- Peggy Sylopp In this talk, we present Sinceare’s closed-loop personalization approach for hearables. Instead of relying on predefined fitting rules or static presets, users teach the system how it should sound through interaction and feedback. These preferences are transformed into personalized machine-learning models that learn how to control existing audio processing algorithms according to individual preferences. Rather than replacing audio DSP algorithms, the generated models act as an adaptive control layer that continuously adjusts algorithm parameters based on user-specific listening preferences. Based on more than eight years of research and a recent study conducted with Fraunhofer IDMT and Charité, we will share insights into user-driven audio model generation, human-in-the-loop machine learning, and the path from research prototype to future embedded hearable deployment. **Spotykach, a looping playground** \- Vlad Litvinenko Vlad is a Berlin based software developer doing e-commerce by day, bleeping machines at night and sometimes music in between. The talk is about device they’ve recently built. It’s “Spotykach”, a looping playground, as they call it. It started from an attempt to do a simple Beat-Repeat kind of plugin, but then evolved into a community project within Synthux Academy with people from different backgrounds and countries.

The result is inconsistent calls and a feeling that marketing is not working. We will walk through the three places every local business needs to show up, plus the fourth place most owners ignore that quietly produces the warmest leads. **What to expect** Doors open at noon. Order lunch and drinks at the cafe counter or bring your own. You get real conversation with other local owners and a focused marketing lesson. You leave knowing people and with one to three actions to run that week. The room is reserved through 1:30 PM. **Who this is for** Any local business owner who wants clearer marketing direction and real local relationships. Service businesses, retail, home services, professional services, online owners building local presence, anyone serious about being part of the Columbus business community. **Not the right fit if** You are here to pitch the room or recruit for an MLM. **Details** * Second Monday of every month * 12:00 to 1:30 PM * Good Cafe Easton, 4400 Easton Commons, Ste 150, Columbus, OH 43219 * Order lunch and drinks at the counter when you arrive * Free to attend, RSVP required, space is limited **About the host** Rita Suzanne is a local marketing strategist and the founder of Local Marketing Method.
