Open Source Python

**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.

**Title**: Amplifying Engineering Skills with Claude Code In this session we will dive into how Claude Code can augment modern engineering practices, from rapid prototyping and refactoring to test generation and documentation. We’ll cover real-world use cases, integration patterns, and tips for getting the most out of AI in your development lifecycle. 6-6:30p.m. - food & drinks 6:30-7:30p.m. - Presentation 7:30-8:00p.m. - Q&A and Possible concept presentation for feedback

Hey everyone, Let’s get together for a relaxed evening of good food and great conversation. If you’re into Python, tech, or working on any kind of project, this is a chance to connect, share ideas, and learn from each other in an informal setting. No presentations, no pressure—just real conversations with people who enjoy building things. Whether you’re deep into development or just getting started, you’re welcome to join.

**Inflow 6:00 PM - Talks Start \~6:30 PM** **Reston Community Center - 2310 Colts Neck Rd, Reston, VA 20191** NoVA Hackers is a group located in the Northern Virginia area and is made up of Information Security Professionals from all walks of life, from government and private sector, to students and beginners. The monthly meetings are held much like a mini-conference with 4-8 speakers and only a few basic but strict rules. Participation and Permission Active Participation is required for continued membership and is the only due required. Permission is required to be obtained from anyone providing information to the group from the person providing it to be made public by anyone other than the provider. Historically our talks generally run a bit late and we have a hard stop at 9:30pm for the room. If you want to socialize we recommend you arrive at 6 to meet and greet before the talks. Agendas and remote meeting option available after you join the group.

It’s hard to believe our group is 1 year old now! Let’s have another great meetup to enjoy the hobby with each other and have a IFP&P birthday celebration! Note: location may change.

We will be meeting at Starbucks to learn together. Come with an online class you're already going through or an interest and we will try to connect you with a course where you can learn it. Already have a skill you want to contribute to a Kaggle Datascience competition? We will work on these too! Laptop required :)

Non-programmers are absolutely welcome—you don’t need to know how to code to join. This meetup is for anyone interested in tech. You can share what you’re working on, propose ideas, or just talk about technology. We typically meet once a month at the Centreville Regional Library, with occasional meetups in Chantilly or other nearby libraries depending on availability. We usually start with a totally optional intro circle. You can share as much or as little as you’d like—your name, background, interests, what you’re working on, or simply pass and listen. If you have any questions, comments, or concerns, feel free to reach out: timothyfilippone@gmail.com
