Building systems that scale. Writing code that lasts. ☕
I'm a Software Engineer based in India with a deep love for backend systems, distributed architecture, and clean code. I believe every complex problem has an elegant solution — it just takes the right abstraction.
A little more about me:
- 🏗️ Obsessed with System Design — from load balancers to distributed transactions
- ☕ Java is my home language — I think in objects and patterns
- 🤖 Exploring Machine Learning from first principles
- 📚 Currently re-reading Effective Java by Joshua Bloch (for the nth time)
- 🧩 I enjoy solving hard algorithmic problems and understanding the why behind them
// My engineering philosophy
while (codeQuality < perfectCode) {
read();
practice();
refactor();
codeQuality++;
}
