Hey — thanks for dropping by 👋

Devanshu Koli — Backend Engineer who builds intelligent systems

Problem solver. Backend-first thinker. AI explorer.

🚀 About Me

I love solving problems — technical, architectural, ambiguous, messy — doesn’t matter.
Give me unclear requirements, production bugs, scaling issues, or a half-broken repo. I’ll break it down, systemize it, and ship something clean.

I built my foundation in Node.js and backend engineering.
Now I’m transitioning into building AI-powered systems — not just using APIs, but understanding how intelligent systems work end-to-end.

Open-source shaped my learning journey. I owe a lot to it — and I actively try to give back.

🎯 Currently

• 🔎 Actively looking for:
  Node.js Developer | Backend Engineer | MERN Stack Developer | AI-focused Backend Roles

• 📚 Transitioning toward:
  AI Engineer (LLMs, RAG systems, applied ML, intelligent backend services)

🧠 What I Actually Do

Backend Engineering

• Design REST APIs with clean architecture principles
• Authentication (JWT, session strategies)
• Database design (MongoDB schemas, indexing strategy)
• Error handling & logging that actually helps debugging
• CI/CD + Dockerized deployments
• Writing code that another engineer won’t hate reading

AI / Intelligent Systems (Growing Focus)

• Building LLM-powered features
• Experimenting with RAG pipelines
• Prompt engineering with evaluation mindset
• Integrating AI into backend services (not just demos — usable features)
• Exploring model serving and inference workflows

🛠 Tech Stack

🔬 How I Approach Problems

1. Understand the business impact first.
2. Break the problem into smallest testable pieces.
3. Build incrementally.
4. Add logging + monitoring early.
5. Refactor once clarity emerges.

I prefer simple, observable systems over clever but fragile ones.

🤝 What You’ll Get If We Work Together

• Someone who asks good questions before coding.
• Someone who reads documentation before blaming the framework.
• Someone who enjoys debugging more than complaining.
• Someone who wants to grow into building AI-native systems — not just CRUD apps.

🌍 Open Source

I’ve learned more from open-source than from any course.
Reading real-world code, understanding tradeoffs, seeing how experienced engineers structure systems — that’s priceless.

I aim to contribute wherever I can and continue learning in public.

🏆 GitHub Stats

I don’t just want to build software.
I want to build systems that think, assist, and scale.

If you're building something meaningful — especially with AI in production — let's talk.
