About

Who I Am

I'm Jayakumar K — a freelance Python developer and Cyber Security student at Rajalakshmi Engineering College, Chennai.

I build secure, real-world solutions — from system hardening tools and data security utilities to automation scripts and web applications. My passion lies at the intersection of backend development, Linux systems, and secure software engineering.

As a Smart India Hackathon 2025 Finalist (NTRO Problem Statement – Delhi), I thrive on complex challenges that require both engineering precision and security awareness. Every project I build is crafted with clean code, performance, and security in mind.
