I build thingsthat matter.

NIFTY 50 options analysis toolkit — 30+ trading strategies, option chain visualiser, P&L calculator with Black-Scholes, and an LSTM direction model.

Passive WiFi security tool on ESP32 — captures WPA/WPA2 4-way handshakes in real time with a TFT display. Built for learning, not breaking.

Bluetooth security auditor on ESP32 — scans BLE devices, identifies types, flags vulnerable services, and displays a cyberpunk threat dashboard.

A Chrome extension that puts a curated prompt library inside ChatGPT — personas, templates, and real productivity gains for writing tasks.

A fully automated publishing system. I type a title, the script handles SEO, uploads to Notion, and publishes. Zero manual intervention.

A comprehensive fitness tracker — 873+ exercises, real-time workout logging, gamification with leaderboards. People use it daily.
