Summary

I'm a Computer Science undergraduate at GGSIPU (GPA 9.1/10) with production experience across AI-integrated backend systems, Android networking and user-facing products. At Web3Task I architected and launched Traverse VPN — a WireGuard-based Android client that reached 100+ Play Store users within 48 hours — and built REST APIs and async backend workflows for Voice-to-Notes, an AI speech-to-text app with 100K+ users. I've triaged 70+ production issues down from hours to under 30 minutes, led a 4-member internship project team, and directed 6 developers to a live AI-system demo at Smart India Hackathon 2025. My focus: concurrency, networking, databases, reliability, and scalable AI infrastructure.
