About Me

Who I am & what drives me

I'm a Backend Developer with 2.5+ years of experience in designing and developing scalable RESTful services using Java and Spring Boot. I specialize in building production-grade applications with efficient database design, transaction management, and performance optimization.

At Heliverse Technologies, I led backend development for analytics platforms, payment gateway integrations, Wix plugin services, and CRM system integrations. I designed and implemented microservice-based architecture and built secure REST APIs with JWT authentication.

Currently at Togethring Media Labs, I'm developing and maintaining high-performance backend services, implementing core modules like Customer Management System (CMS), payment gateway integration, and role-based access control (RBAC). I'm passionate about writing clean, maintainable code and contributing effectively in fast-paced development environments.
