Stream Processing

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.

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!

It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Here is the secret of being positive and free: Thinking positively is not enough. You also have to get rid of the negative thinking. Your mind is like a garden. You can plant many beautiful flowers in it, but if you don't get rid of the weeds when you plant your flowers, the weeds will soon take over the whole garden. A positive thought is like a flower in your mental garden, and a negative thought is like a weed. You cannot expect to have a positive mindset if you continue to have negative thoughts dwelling and growing there. So, how do you get rid of the negative thoughts? That's what this Meetup is all about. Attend this local meeting and find out! The Meetup event will be led by a consultant who had helped many people live happier 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 group is created by the Dianetics & Scientology life improvement center.
