Dear Community, after so many workshops, and a breathtaking Hamburg Summit, it's time to greet the sunshine and carry on the spirit of our beloved city! We have three amazing talks prepared for you this time! Thanks to our loyal host **Bonial International GmbH** \- we look forward meeting you all on the date\! =================================================== 18:15 - Warming up and networking chat 18:30 - Intro by AWS UG Berlin & Bonial 18:45 - 19:10 - **Alexey Grigorev // Zero-Trust AWS Access for Humans and AI Agents** Alexey will share two real-world stories about managing AWS access securely outside of AWS itself. First, he will show how he organized a hands-on workshop where participants used personal laptops and GitHub Codespaces to provision infrastructure in their AWS account — without ever receiving long-lived AWS credentials. They needed something similar to EC2 instance profiles, but for arbitrary external environments. Then he will talk about AI agents and autonomous tooling. Alexey's agents run on non-AWS servers with intentionally restricted permissions. Sometimes they need temporary access to AWS sandbox environments, but he doesn’t want permanent credentials on those machines. Alexey will show an approach for granting short-lived, revocable AWS access on demand. 19:10 - 19:35 - **Surjeet Singh Sachdeva// A Journey From Five Certification Reschedules to AWS Golden Jacket and AWS Ambassador** In this session, Surjeet will share his journey of working through the AWS certification path, leading to the AWS Golden Jacket, along with the practical steps, discipline, and consistency required to reach it. He will also explain what the Golden Jacket represents in the AWS ecosystem, including the recognition, credibility, and deeper access it brings within the community, and how professionals can approach the certification journey in a structured way. 19:35 - 20:00 - Networking break with food, snacks and drinks 20:00 - 20:30 - **Abdul Wahid // Deep Dive into Bedrock to Implement HITL Architecture** With the help of AWS Bedrock and his personal domain knowledge in the field on banking, Abdul Wahid will demonstrate The Human-in-the-loop (HITL) architecture by adding a layer of foundation model in the process to analyse the fraudulent transaction and return a confidence score. If the confidence score is below the defined threshold, then the system will alert the human to make the decision rather than letting AI to make mistakes. 20:30 - 20:50 - Common Q&A Round for all speakers. =================================================== **Very Important: There is no "waitlist" for our regular sessions.** However, there are limited seats available.

Together with Capgemini, we’d like to invite you to our talk in June. This time, we’ll be discussing spec-driven development with Simon Martinelli. **Spec-Driven Development in Practice: How AI Simplify Full-Stack Java** AI is transforming how we develop software, but many teams still treat code as the source of truth, leading to outdated documentation and hidden business logic. What if specifications became the single source of truth instead? This session introduces Spec-Driven Development (SDD) and the AI Unified Process (AIUP), a practical approach in which developers write clear, structured requirements, and AI generates everything else: diagrams, code, and tests. When requirements change, the system stays consistent automatically. Based on a real-world Java project built with Spring Boot, jOOQ, and Vaadin, the most productive and secure web framework for Java, you’ll see how SDD keeps business rules, data access, and UI perfectly aligned. Join this session to learn how AIUP helps Java developers deliver applications faster, with less boilerplate and more focus on what really matters: understanding the domain. Most teams still treat code as the source of truth, leading to outdated documentation and hidden business logic. In this session, you’ll learn how Spec-Driven Development (SDD) and the AI Unified Process (AIUP) let you define requirements once and generate consistent Java code, diagrams, and tests automatically. Based on a real project with Spring Boot, jOOQ, and Vaadin, this talk shows how to build faster, safer, and more maintainable full-stack Java applications. **Simon Martinelli** Simon Martinelli is a Java Champion, Vaadin Champion, and Oracle ACE Pro with over three decades of experience as a software architect, developer, consultant, and trainer. He is the creator of the AI Unified Process (AIUP) and a strong advocate of Spec-Driven Development. As the owner of Martinelli LLC, he coaches teams to get up to speed with AI-driven development. He regularly shares his insights through international conferences, articles, and his blog, Keep IT Simple (https://martinelli.ch), where he writes about AI, architecture, and modern Java development. He is also a lecturer at two universities in Switzerland, where he teaches software architecture, persistence, DevOps, and cloud-native development.

**Join us for our next Machine Learning in Healthcare meetup in Berlin — proudly sponsored by the QUEST Centre!** Pizza is still back! We are very happy to announce our speaker **Frank te Nijenhuis**, who is a PhD candidate at the ICAI Stroke Lab at Erasmus MC in Rotterdam. With a background in medicine and computer science, he develops deep‑learning models to support real‑time clinical decision-making during stroke treatment. **His talk´s title is:** **Bridging the Implementation Gap in AI for Stroke Interventions: Challenges and Opportunities** **Abstract:** In recent years, rapid advances in artificial intelligence (AI) have led to a proliferation of AI models in medical imaging. However, despite promising performance in research settings, many of these models have yet to translate into meaningful clinical impact. In this talk, Frank will highlight several AI models developed for stroke imaging and examine the barriers that hinder their implementation in clinical practice. He will explore potential pathways to overcome these challenges and conclude with an interactive discussion on co-creation as a strategy to bridge the gap between innovation and real-world adoption. *** 📍 **Location:** “Atrium” conference room, 5th floor, Spreepalais, Anna-Louisa-Karsch-Straße 2, 10178 Berlin 🕕 **Doors open at 6:00 pm** — Talks start **at 7:00 pm!** * 6:00–7:00 pm — Arrival, food, and networking * 7:00 pm — Welcome by the hosts, followed by the talk + Q&A * 8:00 pm — More networking (and possibly more pizza) ⚠️ *Pro tip:* Sometimes only one of the four elevators is working! 📢 **IMPORTANT:** If you RSVP but later realize you can’t make it, *please release your spot* so others can join. *** This meetup is made possible with the kind support of the **QUEST Centre for Responsible Research at BIH**, who are providing both the venue and the delicious refreshments.

Our June Meetup is coming up! Thanks to Snowflake for sponsoring us. **Please register with your real name and email addres and bring a photo id.** You will need to check in upon entry. We are happy to have David Wheeler as our speaker this time. David is ais a long-time PostgreSQL contributor, and creator of Sqitch, a database change management system; PGXN, the PostgreSQL Extension Network; pgTAP, a database test framework, and CITEXT2, the case-insensitive data type. After stints with PostgreSQL Experts, iovation, and The New York Times, he now works on PostgreSQL extensions for ClickHouse. He lives in New York City with his artist wife when they're not exchanging homes overseas. His talk is: *How to automatically release your extensions on PGXN* Today there is no one central distribution point for PostgreSQL extensions. The largest the extension source distribution service PGXN. It contains approximately a third of all known publicly-available extensions, but even those are not all up-to-date. PGXN aims to be the root registry for all extension releases, and plans to publish all releases to allow downstream registries to automate their build processes, as well. As such, it benefits extension developers and the broader PostgreSQL community when it contains up-to-date releases of all known extensions. I'll show you the process to set up PGXN distribution for your extensions, and the tooling to automate releases to keep it up-to-date. The main things to understand are Git, JSON, and GitHub workflows. At the end of the session, you'l have all the information you need to quickly and automatically publish your extension on PGXN.

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.

Join the Columbus AI community for a special event. **Battle of the Personal Agents** is your chance to see what people are actually building with AI agents and personal automation systems. Whether you’re running OpenClaw, Hermes, or a completely custom solution, bring your agent and show the community how it works. We’re interested in real-world implementations: the problems your agent solves, how you use it day-to-day, how it’s hosted and managed, how you built it, and why you’ve chosen to keep using it. Live demonstrations are encouraged, so be prepared to show your code, architecture, workflows, and your agent performing real tasks. This is less about polished presentations and more about sharing practical experience, comparing approaches, and learning from one another. If you’d like to present, please contact Chris Slee (via meetup) before the event so we can allocate enough time for everyone’s demonstrations. Come ready to show what you’ve built, discover what others are doing, and maybe find a few ideas worth taking home. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
