About

Who I Am

I'm a Full Stack Developer passionate about building applications that solve real-world problems — from AI-powered Android safety systems to production-grade web platforms deployed with Docker on cloud infrastructure. My work spans Kotlin + ML Kit for on-device mobile intelligence, Java Spring Boot for robust backends, Node.js for rapid APIs, and React on the frontend. I learn fastest by shipping real things.
