About Me

Building secure, scalable systems

I'm a BCA graduate from IMS Noida (2022–2026) with a deep focus on C++ and Python for backend development. I thrive at the intersection of web architecture and cybersecurity — building robust applications while understanding how to break them to make them stronger.[reference:0]

My work spans full-stack web development (Django, Laravel, CodeIgniter), competitive programming, and penetration testing with tools like ESP8266 deauthers, Wi-PWN, and P4wnP1.[reference:1]
