đĄ Details about Speakers & TalksđĄ
**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.
â 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 DÄ
browski**:
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.
â will speak about:
Most people still assume AWS is not the natural home for .NET and treat C# as a âsecond choiceâ on AWS. That used to be a fair concern in some areas, but itâs no longer the reality. In this talk, weâll walk through what building on AWS looks like when your primary stack is C# and modern .NET.
Weâll 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, Iâll show concrete patterns and trade-offs, including where .NET shines, where itâs 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 â.NET on AWSâ can look like in 2026.

Building Scalable Customer Identity Resolution Pipelines on AWS Using AI
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.

In-Person Event: The Answers to Depression & Anxiety
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 donât 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.

Building Momentum: From Ambiguity to Execution
**Building a great product is one thingâbuilding momentum behind it is another.**
Join **Senior Product Manager Adam Solaiman** and **User Experience Manager Tyson Smith** for a behind-the-scenes look at what it takes to turn complex ideas into scalable products inside large organizations.
In this session, theyâll share how teams move from ambiguity to executionânavigating organizational complexity, aligning stakeholders, and continuously evolving products after launch.
Youâll walk away with insights on how to:
* Build and sustain momentum across teams
* Adapt to changing priorities without losing direction
* Scale products thoughtfully in complex environments
Whether you're driving a new initiative or growing an existing product, this conversation will give you practical strategies to keep things moving forward.
Come connect, learn, and swap stories with fellow product professionals.
