About

I am a passionate Software Developer with experience in Java, Spring Boot, Hibernate, REST APIs, and MySQL, focusing on building scalable backend systems and solving real-world problems through clean, efficient code. I’ve contributed to impactful projects during internships at Paytm, where I optimized backend systems for the Lending vertical, impacting 90M+ users, and at DRDO, where I developed and deployed a secure system to improve performance. As an AI Trainer at Outlier, I refined large AI models in Java, C++, Python, and SQL, improving response accuracy to 90%. Beyond work, I’ve built projects like TripEase (Cab Booking System) and a Train Ticket Booking App, applying microservices, relational mappings, exception handling, and database optimization. With 800+ DSA problems solved, I bring strong problem-solving and system design skills to every project I work on.
