**What You'll Build** A fully working Employee Management REST API with: * **CRUD endpoints** (POST, GET, PATCH, DELETE /employees) * **Pagination**, sorting, and filtering on the list endpoint * **Strong runtime validation** via *zod* * A typed, schema-first database layer via *Drizzle ORM* * **Environment-aware configuration** (development / production) * A multi-database PostgreSQL setup orchestrated via *Docker Compose* * A seed script to populate sample data * A **REST Client** app.http file to exercise every endpoint **What You'll Learn** By the end of this workshop you'll be able to: * Scaffold a NestJS application from scratch with `@nestjs/cli`. * Containerize a Node.js API using a multi-stage Dockerfile and *Docker Compose*. * Run PostgreSQL in Docker with auto-created databases via init scripts. * Load environment variables dynamically from `.env.${NODE_ENV}` files. * Wire up *Drizzle ORM* as a global NestJS module with proper lifecycle hooks. * Define a database schema in TypeScript and generate SQL migrations. * Validate request bodies and query params with *zod* using custom decorators (no class-validator). * Implement pagination, sorting, and filtering the right way. * Translate database errors (e.g. unique_violation) into proper HTTP responses (**409 Conflict**). * Write a seed script that works across environments. * Test the API end-to-end using the **VS Code REST Client**. **Prerequisites** Please install before the event: * Node.js : ≥ 22 [Download here](https://nodejs.org) * pnpm: ≥ 9 * `corepack enable && corepack prepare pnpm@latest --activate` * Docker Engine: ≥ 20.10 (With the Compose v2 plugin, `docker compose`, not `docker-compose`) * Git: latest [Download here](https://git-scm.com) * VS Code: latest [Download here](https://code.visualstudio.com) * VS Code extensions: * REST Client, ESLint, Prettier A working internet connection is required to download Docker images and npm packages.

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!

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.

NFT's are here to stay folks! This is a group for like minded people interested in understanding, leveraging, using, creating for, profiting from, trading too i suppose, NFT's.. everything around them, complexity, fear and exploits, best practices and more. **PLUS** This group will talk AI ART tools, techniques, artists, video, audio, prototypes and more in the AI assisted production space- ART specifically, but we can get into any aspect of some of the cooler things happening in AI in general.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** TBD **YouTube Link** TBD

On Thursday, May 21, 2026, we will meet at the 700N Conference Room at 700 N Hurstbourne Pkwy. Doors will open at 6:00 p.m., and the presentations will begin sharply at 6:30 p.m. Along with an excellent presentation, TEKsystems will provide food. Please RSVP so we know how much food to order. Afterward, we will go to Brick House Tavern for drinks and food to continue the conversation. The session will also be broadcast at https://twitch.tv/TaleLearnCode. ### **GitOps: Easy Deploy and Even Easier Rollback** GitOps isn't just for containers. The methodology of deploying from a build is now baked into our culture. Take it a touch farther with infrastructure as code and a few extra techniques, and you can reliably deploy to any platform: cloud, on-prem, container, PaaS, and more. Join us as we learn the methodology of GitOps, the critical pieces you need in place, and the elegance of rollbacks with GitOps. You'll leave with a working repo of deployment techniques that doesn't consume any paid tools or container-specific techniques.

Join the Columbus AI community for our quarterly gathering — a casual, community-focused evening where everyone has a chance to share, learn, and connect. These open mic–style events give anyone in the community up to **5 minutes** to present a project, share a tool, pose a question, or offer a perspective on the evolving AI space. No slides required — just a welcoming space to exchange ideas and keep the local AI conversation moving. If you’d like to take the stage, message \*\*Chris (the organizer)\*\*with a **title and short description** of what you’d like to share. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
