01 — about

Hardware-first.
Security-minded.

I'm a 4th semester ECE student from Uttar Pradesh, India. My work lives at the intersection of embedded firmware and hardware security — I don't just program microcontrollers, I build systems that detect attacks, log anomalies, and respond in real-time.

Current obsession: building a WiFi Threat Intelligence Node on ESP32 — a standalone hardware security monitor with deauth detection, Evil Twin identification, IoT honeypot, and a local HTTP dashboard with MQTT/Telegram alerting.

I work in ESP-IDF + FreeRTOS for production-grade embedded firmware. Designed transformer-based PSUs, debugged UART/I2C on logic analyzer, hand-soldered SMD. Build-first, always.
