Join SnapSoft and the AWS Serverless community for a night of scaling and security. We’re diving into **multi-agent GenAI** workflows for massive **document generation** on **Bedrock**, paired with a high-stakes look at **enterprise PKI** and the hard lessons learned from intermediate **PCA expiration**. Pizza and beer included! 🍕🍺 **Agenda** 18:00 - Arrival 18:15 - Large-Scale GenAI Document Creation on AWS 18:50 - Tick-Tock: Lessons from a Near-Miss PCA Expiration 19:25 - Networking, **Pizza, Drinks** **Large-Scale GenAI Document Creation on AWS** This session showcases a real-world GenAI solution built on AWS, where Amazon Bedrock and other AWS managed services power a multi-agent workflow for document ingestion, retrieval, and large-scale automated document generation. One of the key outcomes was the ability to generate multiple hundreds of pages in one go, while maintaining structure, context, and quality across complex documents. We will explore the architectural decisions made, how we would improve it today. Along the way, we highlight key trade-offs, common anti-patterns, and emerging best practices for building scalable, future-proof GenAI solutions. **Tick-Tock: Lessons from a Near-Miss PCA Expiration** PKI is the silent engine of enterprise trust, but its complexity often stays hidden until something goes wrong. This session provides a practical overview of enterprise-scale PKI architecture before deconstructing a real-world crisis: an almost expired intermediate signing PCA. We’ll explore the cascading technical fallout across the infrastructure and share battle-tested strategies for maintaining crypto-agility. Join us to learn how to manage these critical lifecycles before the "silent" failures start. **SPEAKERS** **Patrick Nanys** Patrick is an ML Engineer focused on taking AI systems from idea to production. His background spans large-scale NLP infrastructure, LLM applications, agentic workflows, and custom ML systems, both in high-throughput enterprise environments and in client-facing AI projects. **Márton Varga** Márton is a Cloud Engineer at specializing in AWS architectures for large-scale enterprise clients. He has a track record of building complex hybrid networking solutions and robust landing zones using **Terraform and Terragrunt**. With a focus on infrastructure efficiency and security, Márton enjoys deconstructing the "silent" critical systems—like PKI—that keep the enterprise running.

Improving the quality of our breathing can powerfully support our lives. Practicing in the Salt Cave, with the support of 8 tons of salt, is a truly special experience. Everyone knows that during a cold or flu, salt can provide quick support. And of course, we all know how to breathe, because we are alive. Learning proper breathing takes time and a little perseverance. Even one breathing therapy session can bring us a lot of understanding, but for more reliable results, a greater number of repetitions is helpful. What can you expect at such a breathing therapy class in the Salt Cave? After settling into a comfortable seated position, we will go over the basics of proper breathing together, then step by step we will practice these gentle and slow movements with every breath. We warmly welcome you.

This session will cover practical workflows, real-world use cases, and hands-on approaches to integrating AI into your development process. Whether you’re just getting started or already using Copilot, you’ll gain a clearer understanding of how to apply AI-assisted coding techniques to improve efficiency and code quality. All skill levels are welcome, just bring your laptop and curiosity. **📌 Topic 2: “How Betsson Scales AI** **at Org Level – Not Just per Developer”** Speaker: Kevin Nascimento, Data & AI Adoption Lead, Betsson Group In this session, Kevin shares how Betsson runs AI at real organizational scale. You’ll see how custom instructions move beyond per-repo files into a governed, tiered knowledge base used by 1,000+ developers, with department-specific overlays on top. He’ll walk through Agent Mode with mandatory human gates at every step, deep context engineering with live diagrams of what loads (and what doesn’t), and Plan Mode where planning is formalised and compliance-checked before any code is written. You’ll also see multi-agent compliance workflows in action, plus how teams build custom agents and prompts under centralized governance but with full local flexibility. A practical, inside look at building safe, scalable, enterprise-grade AI workflows. **🎯 Whether you’re a developer, engineer, or simply curious about AI in software development, this event offers valuable insights, practical takeaways, and the chance to connect with like-minded professionals.** **Seats fill up quickly, so secure your spot and join us for an evening of learning, networking, and real-world AI applications.**

Get to know others and discover, reinforce & improve yourself through this psychological community game! **"Identity**" is a psychological self-improvement game that lets participants have a glimpse into themselves and each other from different aspects of life and providing opportunity to share relevant experiences and thoughts. You'll get a random simple task with every card you draw such as: **"Most folks are as happy as they make up their minds to be.**" -> How could you use this insight? What does it say to you? How does it bring you forward? "**When did you last have me-time?** What did you do? What things do you usually do for your own joy?" "**Every ending opens up a new gate.**" -> Recall at least 2 painful stations in your life when something important for you ended! What good things could begin thanks to these endings? Substantial short talks in a friendly, respectful, non-judgemental (really: judgements, *even advices* are forbidden by the rules!) environment, while comfortably having a drink. Let others surprise you positively, learn about them, reflect on yourself internally and improve your personal life thanks to select short tasks that aim to bring you forward! **The game will be held in english!** The game only exists in hungarian version, so for instant translation of the cards, **Google Lens is recommended on your phone**! The event will be held in the "Másik Szoba" Café and Bar (part of the Élesztőház): [https://elesztohaz.hu/reszeink/masikszoba/](https://elesztohaz.hu/reszeink/masikszoba/)

💜 Csak nőknek szóló PyLadies esemény! 💜 Sziasztok PyLadiek! Ez alkalommal bepillantunk a legintenzívebben fejlődő AI-technológiák világába. Elsőként pár fogalmat és alkalmazási területet nézünk meg, majd pedig csinálunk Pythonban egy saját LLM-et. Felépítjük komponenseinket, és ki is próbáljuk, mire képes egy alaprendszer. A szünet utáni második részben az igényeinket kibővítjük, a rendszerkomponenseket nagyobb tudású elemekkel helyettesítjük, és így építünk fel egy, a gyakorlatban is használható megoldást, egy lokális RAG-rendszert. 👨‍💻 Előadó: Sepp Norbert 🗓️ Programterv Múltkori alkalmakból tanulva, most hosszabb szünetet hagyunk a ket előadás között, hogy legyen időnk beszélgetni és megismerni egymást :) • 17:30 – 18:00 Megérkezés, setup • 18:00 – 19:00 Előadás I. • 19:00 – 19:40 Szünet, Networking • 19:40 – 20:35 Előadás II. • 20:35 – 21:00 Záró gondolatok, elköszönés (A programterv változásának jogát fenntartjuk.) 💻 Mivel készülj? Workshop jellegű alkalom lesz, így ajánlott, hogy legyen nálad egy programozásra alkalmas számítógép. A meetup előtt egy héttel részletes telepítési és előkészítési útmutatót küldünk. Ha régebbi vagy kisebb teljesítményű géped van, akkor sincs gond – az első részhez nem lesz szükség komolyabb erőforrásokra. 💜 Kit várunk? Olyan lányokat/nőket, akik érdeklődnek az AI és a Python iránt, és szeretnék megérteni, hogyan működnek a modern nyelvi modellek, illetve kipróbálnák magukat egy saját rendszer építésében. 📍 Helyszín Balance Irodaház – 7. emelet Dél (Lifttől balra) Cím: 1139 Budapest, Váci út 99 🌍 Nyelv Az esemény nyelve: magyar (és Python) 🤝 Szponzor HCL Technologies Starschema Kft.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.
