What I'm looking for

I'm looking to focus my career on Java and Spring Boot backend development, building secure, reliable systems and continuing to deepen my work in Spring Security, JPA/Hibernate, and SQL optimization.

I've built and shipped Spring Boot systems including a hotel booking API with Stripe payments and EcomAI, a full-stack e-commerce application with an AI customer-support chatbot.

For the hotel platform, I prevented concurrent double-booking with pessimistic row-level locks, managed JWT authentication and role-based access, built dynamic pricing, and automated refunds on cancellations. In EcomAI, I used Spring AI, RAG, PostgreSQL, and pgvector to keep chatbot responses grounded in current product and order data.

At BeyonData Solutions, I developed Oracle APEX and SQL applications for enterprise workflows, optimizing queries, database objects, forms, reports, validations, and business logic.

Earlier at Confidosoft Solutions, I built React modules for a regulated clinical-trial eCRF platform, integrated REST APIs, resolved 10+ frontend and integration defects, and improved deployment documentation and release stability.
