Hi everyone! 👋

My name is Bohdan, and I’m a Junior Full Stack Developer from Ukraine.

I recently started my first commercial job at 18. It’s been a crazy week of onboarding, setting up environments, battling with Jira, and diving into the codebase.

🛠 My Tech Stack:

I'm currently working with:

Backend: NestJS (Node.js) + TypeORM
Frontend: Next.js (React)
DevOps: Docker

🎯 What I'll write about:

I plan to share my journey here on DEV:

Real-world problems I face as a Junior.
Tips on NestJS & Next.js architecture.
How to survive your first months in IT.

If you are also a beginner or just love TypeScript ecosystem — let's connect!

Happy coding! 💻

Student vs. Microservices: How I Built an AI Platform at 18 Instead of a To-Do App

Hi Dev.to! I'm Bogdan, and I just turned 18. While many start their coding journey with a simple To-Do list, I decided to go deep into the rabbit hole of microservices for my project, SkillSwapAI.

I’ve spent the last few months architecting a system that isn't just a monolithic block. Here is my current stack:

Backend: NestJS handles the core logic and user management.
AI Engine: A FastAPI service in Python that generates study plans using OpenAI.
Cloud Infrastructure: I’m using AWS Lambda, S3 for storage, and CloudFront for content delivery.
Database: PostgreSQL with Prisma ORM.

Architecure:

The biggest challenge wasn't the code itself, but making these services talk to each other efficiently via HTTP. I’m currently refactoring parts of it to LangChain to make the AI features even smarter.

I’m starting my first official job as a Full Stack JS Developer on January 28th, but this project is where I truly learned how to be an engineer. Check out my full architectural breakdown on Medium"
