About

I’m a Backend Engineer with 2+ years’ experience in building scalable distributed systems. At SHL, I improved fraud detection accuracy by 20%, scaled onboarding systems 20x, and boosted user engagement by 55%. As a founding backend engineer for a learning app (10K+ MAUs), I architected the system end-to-end, cutting infra cost by 40% and improving retention by 18%. With a strong background in Java, Spring Boot, Node.js, AWS, and competitive programming (ACM ICPC regionalist, CodeChef ~2000), I’m passionate about solving high-scale engineering challenges that impact millions.
