About Me

I'm a Full Stack Developer with 2+ years of experience building production-grade microservices platforms at scale. Currently at TCS, working on a hiring platform serving millions of users across India and the US.

I specialize in Java/Spring Boot backends, event-driven architectures with Kafka, and clean React frontends. I'm passionate about system design, performance optimization, and writing code that holds up under pressure.
