"I'm a Senior Backend Java Developer with 4+ years of experience building secure, scalable systems for fintech and banking platforms. I've worked on real-world projects like AU Small Finance Bank's net banking platform, a real-time fraud detection system, and a bill payment platform integrated with multiple payment gateways. My core stack is Java, Spring Boot, and Microservices. I've led secure auth systems using OAuth2 and JWT, migrated SQL databases to MongoDB for better scalability, and optimized backends to handle high concurrent traffic. What drives me is solving complex backend problems and delivering systems that are not just functional but production-ready, secure, and built to scale. I'm currently looking for opportunities where I can contribute to high-impact fintech or backend engineering challenges."
