What I'm looking for

I’m looking for a Java backend role where I can build scalable, secure REST APIs and grow into Spring Boot and system design. I value clean architecture, measurable impact, and collaboration that helps me deliver production-ready features.

I’m a software developer with strong foundations in Java, OOP, and data structures, and hands-on experience designing RESTful APIs and building scalable web applications. I’m currently deepening my Java backend skills with a focus on Spring Boot and system design fundamentals.

In my projects, I designed and implemented RESTful APIs for vendor registration, service listings, and user workflows, structuring the backend with a modular MVC architecture for maintainability. I also designed MongoDB data schemas and implemented optimized CRUD operations for dynamic service management.

I built a full-stack ride matching platform that connects riders with drivers using overlapping routes to enable fuel-sharing, not traditional ride-hailing. I implemented JWT-based authentication with role-based access control, protected routes, secure password management with bcrypt, and location-aware matching using React-Leaflet and geolocation tracking.
