Backend developer and application-security enthusiast from Kerala, India. I build secure APIs with NestJS, FastAPI and Python — OAuth, JWT and RBAC are my home turf — and I like breaking things ethically to learn how to build them better.
I'm George, a Computer Science student at Karunya Institute of Technology and Sciences, originally from Thrissur, Kerala. I spend most of my time on the backend — designing APIs, wiring up databases and making sure the whole thing doesn't fall over when real users show up.
My speciality is authentication and authorization. As a Software Engineer Intern at FirstMeridian Business Services I implemented OAuth-based third-party login and a role-based authorization system, and built migration tooling between ticketing systems while coordinating with external vendor teams.
I founded and led the Cyber Security Club at Karunya, running events and competitions to grow the campus security community. Before that, an ethical hacking internship at Tech By Heart had me working on client-side malware execution and privilege escalation — the offensive side that informs how I defend.
Away from pure backend work I like building odd things: an AI intrusion detection system using Random Forest classifiers, and an ESP32 + MPU6050 fall-detection device with Blynk-powered smartphone alerts. If it has a sensor or a dataset, I'll probably poke at it.
