# About_Me
Roshan Melvin G A
Backend Engineer · AppSec · Infrastructure
Chennai, Tamil Nadu, India
// Currently Learning
I engineer secure, high-performance backend systems. My focus is Java enterprise architecture and application security — designing resilient services, automating infrastructure, and building developer tools that prevent vulnerabilities by default.
Currently pursuing a B.E. in Computer Science (IoT focus) at Sri Sairam Engineering College. I work at the intersection of Java backend development, applied AI, and application security - shipping everything from Linux boot images to AI-powered security tooling.
// Current focus
Building JavaSAST - an AI-powered static analysis engine for Java that detects OWASP Top 10 vulnerabilities using taint analysis and suggests fixes via the Claude API.
