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.

**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.

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 1266 Dublin Road, Columbus, OH 43215 For more information, contact Rhiannon, the Event Host at 614-221-5024

Who else is ready to sit outside? Join us for a casual chat over coffee & tea at Grandview Grind! Come out and meet some new people, enjoy your favorite drink, and make some new friends!

This is an in-person meeting. Would you like to know the Real You, not just a shadow of yourself? Does your life energy feel somehow trapped within? Does your self-confidence get easily shaken?

Perhaps you get weighed down with negative emotions you can't seem to shrug off. Or find yourself doing strange and irrational things - not really being yourself. We will cover why that is and tools that work to help you unearth your self, your self-confidence and motivation. This meeting will help you learn about how to effectively overcome: -Out-of-control unwanted emotions -Low self-esteem -Anxiety -Negativity -Stress -Irrational fears -Traumatic or painfully emotional incidents -Breakups -Betrayals -Feeling like you're not really yourself -Self-doubt... We will discuss how to unleash the inner you and tap into your true potential. So come to this online meetup! This meeting is sponsored by the Hubbard Dianetics Foundation of Central Ohio

Let’s meet and wander the galleries! General admission on Sundays is free.

Do you want more motivation and confidence to build Lasting Relationships? This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Are you burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival, while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? 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: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in 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 class is held at the Dianetics and Scientology Life Improvement Center.
