Security & CTFs

Cybersecurity is how I got into code.

Before I was writing backend systems, I was breaking them. I ran my first CTF challenge in college, got hooked, ended up on a team, and eventually co-organized one of my own. That background shapes how I write production software now — I assume things break, I look for the boundary conditions, and I don’t trust inputs.

Feature

NoEscape CTF 2022 / NECTF

A jeopardy-style international CTF organized out of Roorkee Institute of Technology in November 2022. Two-person core team. 24-hour online event with a parallel onsite component — 137 teams registered on CTFtime, 400+ active participants from 25+ countries competing on challenges in web, pwn, forensics, steganography, crypto, OSINT, and trivia.

The hard part wasn’t writing challenges. It was everything else: infrastructure that didn’t collapse under load, scoring and flag-submission that worked under partitions, a communications plan for 25+ time zones, and judging escalations at 3 AM. I learned more about running reliable systems from that weekend than from most production incidents since.

Team

F7 Conquerors

I’ve competed and organized with F7 Conquerors — an India-based CTF team active on CTFtime since 2012. My active era was 2022–2023, around NECTF and the finals/quals listed below.

Hackathon

Smart India Hackathon 2022 — Grand Finale

Built Verifi, an offline OTP authentication system, for a DRDO problem statement. The challenge was real: field authentication in environments where connectivity is adversarial or absent. We designed a scheme that worked with seeded secrets + time-based derivation, no live server call required.

The project made it to the Grand Finale — the top shortlist out of thousands of participating teams nationally.
