I'm Ranjan, a security researcher who started by asking how links and messages work and stayed because breaking them proved more interesting. My work spans web applications, Android, APIs, cloud, and network security. I prioritize hands-on testing over theory and have spent a questionable number of hours solving 200+ Hack The Box labs and 900+ TryHackMe challenges, earning a top-5 rank on the TryHackMe India leaderboard. I hold multiple industry certifications, practice responsible disclosure, and prefer finding bugs before attackers do. The field keeps changing, so I keep learning, challenging assumptions, and fixing systems that were "working fine.
