> Computer Science student at KIET Group of Institutions (2024–2028), building things that actually work at scale.

> I live in two worlds: Flutter for production mobile, and C/CUDA/Assembly for the metal underneath.

> I don't chase trends. I write code that compiles fast, runs faster, and doesn't need a second explanation.

> Currently focused on GSoC 2026, adding multi-protocol support to API Dash — because WebSocket, MQTT, and gRPC deserve first-class treatment in a dev tool.
