⚡ About Me

Coding

I'm a 3rd Year CS Student at MJCET, Hyderabad — obsessed with building systems that are fast, correct, and elegant under pressure.

I don't just use libraries — I build from scratch:

  • ⚡ 71,000 RPS fraud detection with XGBoost + ONNX + Go

  • 🔀 2 PRs merged into 12K+ and 3K+ star OSS repos

  • 💻 300+ LeetCode problems solved

  • 🌍 4 AI applications deployed on Vercel

  • 🔨 Currently building distributed systems & AI apps

  • 🌱 Studying from Stripe & Cloudflare engineering blogs

  • 🤝 Open to SWE internship opportunities

  • 🌐 Check out my Portfolio

  • ⚡ Fun fact: I debug better at night ☕
