Nitin Ahirwal | Engineer, Developer & Tech Enthusiast

Hey folks,
After years of working across stacks, scaling projects, fixing bugs at 2 AM, and running my own agency — I’ve decided it’s time to rebuild my foundation from the ground up.

Welcome to code90 — a 90-day journey where I revisit everything I’ve learned in Web Development, DevOps, Web3, and real-world engineering.

🚧 Why code90?

I’ve been fortunate to work on a variety of projects and technologies — from MERN stack apps and deployment pipelines to Solana smart contracts. But as tech evolves, so should we.

code90 is my personal challenge to:

Relearn the fundamentals
Master modern workflows
Document everything openly
Share real projects, not just tutorials

🛠️ What I'll Be Covering

Over the 90 days, I’ll deep-dive into:

Web Development: MERN stack, API building, UI/UX workflows
DevOps: Docker, CI/CD, cloud deployment, performance
Web3: Smart contracts, wallets, Solana ecosystem
System Design: Architecture, scaling strategies
Projects: Real-world builds, daily logs, and debug sessions

Each day’s notes will live in a GitHub repo — organized and blog-ready: 📂 code90

🧪 How You Can Use It

Follow along day by day
Fork the repo and start your own
Use the projects as templates
Remix the ideas for your stack
Or just learn something new each day

🔗 Follow My Journey

This journey is public, raw, and real — and I’d love to connect with others doing the same.
