About
A bit about me
I'm a Full Stack Developer and 2× startup founder with over four years of experience building production-grade software — from AI-powered hiring platforms to immersive 3D restaurant tech.
I thrive across the full stack: architecting backend systems on Node.js & NestJS, building polished frontends with React & Next.js, and shipping mobile apps with React Native. I've also founded AIForJob.ai, an AI-powered career coaching platform, and Dine3D, a 3D restaurant experience product.
Outside of code, I've competed at state level in chess and skating, built 20+ hardware projects with Arduino, and published apps used by real students and communities. I believe in ownership — from the first line of code to the last deployment.
“Strong believer in shipping fast, learning faster.”
