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.

Jimmy V's Grill & Pub in Grandview Heights. You are responsible for your own meal/drinks.

**Latest Dojo Location!** **Knotty Pine Brewing** 1765 W 3rd Ave, Columbus, OH 43212 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for speakers for our Monthly Meetups! Fill out the form if you are interested in presenting to the Python Community. https://forms.gle/ehSfUAC2WgR34Crq9

This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.

We will show how to build custom agents with Microsoft Agent Framework. Attendees will learn how to build and custom host agents when Microsoft Foundry is not a viable option.

Communication is everything in life! You are only as successful as your ability to communicate. \- What if you could confidently talk to anyone? \- What if you had the ability to calmly control every conversation? \- What if you could close that sale\, ask for that date\, make new friends\, repair problematic relationships\, get that raise\, or effortlessly express any idea with confidence? You can! The secret to success relies on your ability or inability to effectively communicate. Attend a free seminar and gain a better ability to communicate. Hosted by the Church of Scientology of Central Ohio For more information, contact Rhiannon, the Event Host at 614-221-5024

**Welcome to Drunken Philosophy** a casual, curious social discussion **Optional topic for this meetup: What's up with all the AI hate?** A recent survey found that 74% of Americans have a negative view of AI, and I want to know why. Come out and debate whether AI is good or bad. My hot take: a labor-saving tool that could potentially help cure cancer gets called dangerous because it might raise unemployment or cause a speculative investment bubble, that tells you a lot more about capitalism and the economic system we live under than it does about the tool itself. As a computer programmer, I think AI is a wonderful tool that has increased my productivity by at least an order of magnitude. I'd go so far as to say Claude Code is the best tool I have ever used. Debate me and name a better one. Is AI potentially dangerous? Yes, but so are a lot of tools. Chainsaws. Steam engines (early ones would occasionally explode and kill everyone in the room). Do you think cavemen sat around debating whether fire could be used as a weapon or for self-harm, and decided not to discover it? I have two friends who hate AI for opposite reasons: one thinks it's a fad and not useful, and the other thinks it's going to take over everything and cause human extinction. Come out tonight, have a friendly debate, and make some friends. No lectures. Friendly crowd. Drop in for one drink and stay if it's fun.
