**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.

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

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!

Main Library, Meeting Room 2B Join us for a welcoming evening of reflection, gentle music, and meaningful conversation. We’ll begin with a short grounding moment, followed by a brief reading from spiritual or philosophical traditions, and an open reflection circle where participants can share (or simply listen). Libera Animae is an interfaith community focused on inner growth, creativity, and authentic connection. All backgrounds are welcome.

**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

Join us for our May Book Club gathering where we will come together to discuss *[Cantoras](https://caroderobertis.com/books/cantoras/)*[ ](https://caroderobertis.com/books/cantoras/)by [Caro de Robertis](https://caroderobertis.com/bio/) in a safe and welcoming environment. Make new friends who share your passion for books and connect with fellow LGBTQ book enthusiasts.

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.

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.
