What I'm looking for

I'm looking to build production-grade backend, microservices, FinTech, or AI-powered systems where I can deepen my Java, Spring Boot, distributed systems, and GenAI experience while solving meaningful scalability and reliability challenges.

At Coderoxygen, I built a 12+ service Java and Spring Boot microservices ecosystem for a live quick-commerce startup, improving fault tolerance by 40% and removing single points of failure through isolated domain services.

I engineered an API gateway that reduced client-to-service latency by 25%, asynchronous Kafka-style notification workflows that reduced main-thread blocking by 30%, and PostgreSQL query improvements that increased dashboard query performance by 50%. I also built payment-service state management and geolocation and search modules for faster delivery matching and inventory lookups.

I bring practical GenAI experience through an AI-powered resume screener using Spring AI and OpenAI, alongside secure payment-platform work with JWT, TOTP 2FA, Razorpay, Docker, PostgreSQL, and React. I’m backed by strong problem-solving fundamentals, including a LeetCode Knight badge, a top 3% global rating, and 800+ problems solved.
