Most developers build apps. I build them and then try to break them that's what makes the difference. I started as a full-stack developer working across web apps and mobile (Android & iOS). Over time I moved deep into cybersecurity not as a career switch, but as an extension. Understanding how code is built is exactly what makes me better at breaking it. On the development side: 1. Web apps and websites: frontend to backend 2. Mobile apps: Android & iOS 3. REST APIs, authentication systems, database architecture On the security side: 1. Web Application Penetration Testing (OWASP Top 10, auth flaws, injection, business logic) 2. Mobile App Pentesting: Android APK reversing, insecure data storage, API security 3. Vulnerability Assessment & Reporting with actionable remediation 4. WordPress security, hacked site cleanup, hardening 5.Network & Infrastructure Security Currently working with NST Cyber on enterprise CTEM (Continuous Threat Exposure Management) securing banking and government portals internationally. Ranked Top 50 in India on HackTheBox. Featured in 40 Under 40 Rajasthan Patrika.
