Next AWS meetup is up to date. This chapter is dedicated to **cloud migration** and **a developer-first tour of the AWS services**. 🗓 **Save the Date**: Mark your calendar 🍕 + 🍺 = Let's gather around pizza and beer at **Hevre** or Watch the stream on [YouTube (link)](https://youtube.com/live/x2YENCV4jnU) Hosted by: **Maciej Lelusz**, AWS Hero AWS Community Builders: **Maria Kmita** 🎤 **Speakers**: 〰️ *„Cross-Account, Cross-Region,* *Cross-Fingers – Migrating a Live AWS Platform"* **Volodymyr Hordiienko**, DevOps Architect at Intellias 〰️ *„NET on AWS: Better Than You Think"* **Wojtek Dąbrowski**, AWS Hero 💡 Details about Speakers & Talks💡 **Volodymyr Hordiienko:** DevOps Architect with over a decade of experience in multi-cloud infrastructure, platform engineering, and delivery automation. Designs and builds production-grade environments across AWS, Azure, GCP, and hybrid on-prem - covering architecture, infrastructure-as-code, CI/CD pipelines, container platforms, security, and operational reliability. Has led cloud migrations, platform modernizations, and greenfield builds across industries, including telecom, healthcare, IoT, finance, and retail. ☞ will speak about: A practical AWS migration story about rebuilding a live platform from a single-account, manually managed setup into a governed multi-account delivery model. The talk covers Terragrunt/Terraform, ECS Fargate, RDS, S3, CloudFront, Lambda, Cognito, CI/CD, cross-account deployments, mobile release pipelines, enterprise IAM constraints, and the operational reality of getting an AWS platform truly ready for production. **Wojtek Dąbrowski**: is a Solutions Architect and backend engineer with over a decade of experience, working primarily with AWS. He stays hands-on with code and delivery, combining practical engineering with architecture and technical decision-making. Currently, he is a Platform Tech Lead at Northmill Bank. Since 2019, he has led AWS User Group Silesia in Poland, and in 2023, he was recognized as an AWS Hero. ☞ will speak about: Most people still assume AWS is not the natural home for .NET and treat C# as a “second choice” on AWS. That used to be a fair concern in some areas, but it’s no longer the reality. In this talk, we’ll walk through what building on AWS looks like when your primary stack is C# and modern .NET. We’ll take a developer-first tour of the AWS services that make .NET a strong fit: serverless workloads (APIs, async processing, event-driven systems), container platforms, and infrastructure-as-code written in C#. Along the way, I’ll show concrete patterns and trade-offs, including where .NET shines, where it’s neutral, and where you should be honest and pick a different tool. The goal is simple: leave with a clear mental model, practical options you can use immediately, and a refreshed view of what “.NET on AWS” can look like in 2026.

Spotkania z serii wymiany wiedzy podczas wspólnego rozwiązywania zadań CTF – jest to świetna zabawa pozwalająca równocześnie rozwinąć wiedzę w zakresie cyberbezpieczeństwa. Poziom trudności CTF-owego zadania ustalimy na początku spotkania. Najprawdopodobniej wybierzemy coś z platformy Hack The Box. Spotykamy się **co tydzień w środę o 19:00.** \-\-\- Zaczynamy o 19:00, ale warto sprawdzić https://at.hs-ldz.pl – być może ktoś otworzy siedzibę wcześniej.

Zapraszamy wszystkich fanów śpiewania (lub próbowania śpiewania) na karaoke w naszym hakierspejsie. Umiejętności wokalne niepotrzebne, nawet niezalecane. Równocześnie w siedzibie hakierspejsu będzie odbywało się także spotkanie planszówkowe.

Zapraszamy na kolejne spotkanie planszówkowe! Mamy parę gier w spejsie, ale zachęcam przynieść również własne gry! Chętnie zagramy w coś nowego. Jest też miejsce na zostawienie gier na jakiś czas w spejsie, żeby nie musieć ich targać tutaj co tydzień. \-\-\- Zaczynamy o 19:00, ale warto sprawdzić [https://at.hs-ldz.pl](https://at.hs-ldz.pl) – być może ktoś otworzy siedzibę wcześniej.

Join us for another session of our study group as we continue our coverage of the book Domain-Specific Small Language Models. In this session, we will attempt to cover Chapters 13 on "Creating end-to-end applications", which explores RAG and Agents and Chapter 14, on "Advanced Components for LLM Applications", which explores GraphRAG. This isn't just a lecture! Come ready to ask questions, share insights, and code along. Whether you're a beginner or have some experience, this is the perfect opportunity to continue to learn together. If you plan to work with the code on your own laptop during the session, try and download the code from here https://github.com/virtualramblas/Domain-Specific-Small-Language-Models ahead of time.

Join our new group’s third meeting. Meet fellow tech enthusiasts west of the beltway. ​Because our group is new, we have a poll for the direction we want to take this new group. ​[https://submatrix.net/article/Meetups/e9ym4fr8Ca](https://submatrix.net/article/Meetups/e9ym4fr8Ca) ​For this event, we will be running a working meetup. ​Our meetings are a great place to work on and show off what you do. We are always welcoming. ​Our format is great for people who have started on but not finished one or several side projects. ​We will start off with basic introductions and what we are working on and what our goals are. We’ll break the rest of the meeting into two working sessions. In between, we’ll do a quick check-in to see how folks are going. If the RSVP is full, come anyway. We'll likely have space.
