What I'm looking for

I'm looking for a backend engineering role where I can build secure, scalable Java and Spring Boot services, work with cloud deployments and databases, and grow through challenging product and system-design problems.

At GEOCO India, I engineered a modular Java 21 and Spring Boot e-commerce backend with 60+ REST endpoints covering authentication, catalog, cart, checkout, orders, payments, support, and admin workflows. I improved product and category API response times from approximately 250–300 ms to 150–200 ms through Redis cache-aside caching.

I’ve also built Task Sketch and Splitwiser, secure backend applications using Java, Spring Boot, PostgreSQL, Docker, JWT, Google OAuth 2.0, and Razorpay. I enjoy designing reliable REST APIs, modelling transactional data, implementing secure backend workflows, optimizing performance, and deploying production services.
