Lean Project Management

[English version below] Cześć, Mam ogromną przyjemność zaprosić Was na pierwsze spotkanie organizowane wspólnie z łódzkim oddziałem **EPAM**. W planach dwie prezetacje odnośnie AI: **Java RAG: Build Your Own Black Box** oraz **Spring AI**. **Ważna uwaga: spotkanie wyjątkowo zaczyna się o 17:30!** Hi, I’m very happy to invite you to our first meetup, which is being organized in collaboration with the Łódź branch of EPAM. We have two AI-related talks planned: **Java RAG: Build Your Own Black Box** and **Spring AI**. **Important note:** this meetup will **start at 17:30**. **Spring AI** Transforming your existing Java applications into intelligent, AI-driven systems no longer requires a PhD in Data Science or switching to Python. In this session, we explore how Spring AI brings the familiar power of the Spring ecosystem - portability, modularity, and POJO-based design - directly into the world of Artificial Intelligence. We’ll move beyond basic API calls to show how you can harness Large Language Models (LLMs) like OpenAI and Google Gemini using the same @Service and dependency injection patterns you use every day. We will provide an overview of the major capabilities and also dive into the latest Spring AI v2 milestones that position Java at the forefront of the agentic AI wave. By the end of this talk, you’ll see how Spring AI acts as a bridge that allows Java developers to build production-ready, intelligent features without reinventing the wheel. **Dzmitry Sidarenka** Dzmitry has nearly 20 years of experience specializing in systems built with Java. He is passionate about building and testing robust APIs and is known for thriving in high-pressure production incident troubleshooting. His work focuses on designing reliable, maintainable services and improving system resilience through pragmatic engineering practices. **Java RAG: Build Your Own Black Box** Retrieval-Augmented Generation (RAG) often feels like a magical black box. But once you start experimenting with it yourself, it quickly becomes clear how powerful the combination of information retrieval and generative AI can be. Key topics: \- What is Retrieval\-Augmented Generation \(RAG\)? \- Why should you consider using it in your own projects? \- Key RAG components and how the workflow operates \- How to build your own RAG solution using Java \- Live demo of a Java\-based RAG project and ways to extend and improve it **Ahmed Samy** Ahmed is a Senior Software Engineer at EPAM Systems. As he jokes, he often feels like a junior at work - mostly thanks to his constant curiosity and desire to keep learning new things. In his daily work, he actively uses AI as a learning companion, exploring new ideas by experimenting, testing different approaches, and working with various pieces of code. **About the partner** EPAM is a global leader in AI transformation engineering and integrated consulting, serving Forbes Global 2000 companies and ambitious startups. With over thirty years of expertise in custom software, product and platform engineering, EPAM empowers organizations to become AI-native enterprises, driving measurable value from innovation and digital investments.

## Beads: Go Open Source Projects in the Age of AI Hello, 世界! For meetup #58 on Tuesday [Mar 31, 2026 19:00 CET](https://www.meetup.com/leipzig-golang/events/312537698/) we are happy to have [Akim Zmerli](https://www.linkedin.com/in/akimzmerli/) give us an intro to [beads](https://github.com/steveyegge/beads), specifically: > How agents perform long-running tasks and pass context seamlessly to each other. [Beads](https://github.com/steveyegge/beads) is a rising Go project that brings structured planning to any workflow, whether agentic or hands-on. [Akim Zmerli](https://www.linkedin.com/in/akimzmerli/) will present his favorite techniques, TUI projects and what Rob Pike thinks about the current state of affairs. The beads project is less than six months old (2025-10-11), but already well beyond 250 KLOC, with more than 200 KLOC written in Go. We are always interested in developer tools. At [#44](https://golangleipzig.space/posts/meetup-44-wrapup/), less than two years ago, not a single AI coding tool did make it to [our list](https://golangleipzig.space/posts/meetup-44-wrapup/). Looking forward to this foray into the agentic coding space. ### Schedule * 18:45 Doors open * 19:00 Welcome * 19:10 Beads * 19:45 Open discussion We’ll meet: * in person at [Basislager Leipzig](https://basislager.co), at [Peterssteinweg 14, 04107 Leipzig](https://maps.app.goo.gl/1fMkeDSPZ7Aauszh8) ([OSM](https://www.openstreetmap.org/node/3504864558)) * and online via [Jitsi](https://meet.jit.si/LeipzigGophers58) Join us to discuss SOTA dev tools and more.

Pay attention! We’re delaying a week for those of you who may be on Spring break and/or celebrating the holiday. Ok, no pancakes, but waffles-a-plenty. Join the local UX and Digital Design community for a casual monthly breakfast. Look for us upstairs!

We're bringing the community together for a casual happy hour with ServiceNow-themed trivia, food and drinks, and great conversation. Details coming soon - for now, save the date and plan to join us for connection and fun.

Interested? Contact Preston Moore k.preston.moore@gmail.com 614-300-5989 ———————————— Engaging in men’s work is the new way to forge friendships while being open-minded to personal growth. Many men experience healthier relationships, personally and professionally, by engaging in this work. Open Men’s Group is a container for men to share vulnerably without receiving judgment or feedback. We believe that emotionally mature, powerful, compassionate, and purpose-driven men will help heal some of society’s deepest wounds. We support the powerful brilliance of men and we are willing to look at, and take full responsibility for, the pain we are also capable of creating – and suffering. We care deeply about men, our families, communities, and the planet. Visit ManKind Project USA to discover more. https://mkpusa.org/

The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. We will be hearing from Becca Powell, Director of Advocacy and Outreach at Unchained At Last, an organization whose mission is dedication to ending forced and child marriage in the United States through direct services and systems change. Unchained At Last's mission clearly meshes and addresses several of our Humanist Ten Commitments. Becca will educate us about an issue many of us may not be familiar with--but should be. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid. You can meet us in-person or attend online Join Zoom Meeting [https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1](https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1) Meeting ID: 878 3656 4953 Passcode: 760812 One tap mobile +19292056099,,87836564953#,,,,\*760812# US (New York) +13017158592,,87836564953#,,,,\*760812# US (Washington DC) The formal presentation will start at noon

**The idea for this group is to build a community where men can gather together and build connections & learn and grow from each other.** How we start each meeting is by each of us checking in with our "roses and thorns" aka what are the good things and the bad things going on in your life recently? Then we will go into a topic discussion. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **COMMUNITY AGREEMENTS** \*\*THERE WILL BE A ZERO TOLERANCE POLICY FOR NO-SHOWS. IF YOU RSVP TO A MEETING AND FAIL TO SHOW UP WITHOUT NOTICE, YOU'LL BE REMOVED FROM THE GROUP. THIS IS TO PRESERVE THE INTEGRITY OF THE GROUP\*\* 1. Confidentiality - EVERYTHING that is shared NEVER leaves this space so that this space remains safe and sacred. There is a zero tolerance policy for this. If a man is in violation of this, they will be permanently removed from the group. 2. Non-Judgement - we respect and honor every man’s truth so that we may receive the same from others. While we may not agree on everything, we commit to respecting every man’s perspectives and engaging in honorable discussion with one another. 3. Be committed - honor your commitment to this group and to yourself. If you attend a meeting, please commit yourself fully to the meeting. Also be committed to your own journey. When we fail, we own it & clean it up. 4. Speak from the heart - this is NOT a space to “look good”, have the “right” answers, and have it all together. Relax and know you are not alone. Be exactly who you are within the safety of this space. 5. Be supportive - This means always willing to provide encouragement to your fellow men, encourage action and momentum in each other’s lives.. Be willing to challenge each other. Be willing to hold each other accountable. 6. Participation - what you receive from this community will be a reflection of what you put into it. Period. We ask that you share your perspectives, reflect on others, and give/receive support when and where it’s needed.
