About Me

Rethish Kumar P A

Building robust backend systems & clean interfaces.

I am a passionate software engineer with hands-on experience developing enterprise-grade applications. Currently working on CRMS (Customer Relationship Management System) at Wizzmoni, I design and implement RESTful Spring Boot microservices, containerize apps with Docker, and manage complex database operations using PostgreSQL.

Beyond the backend, I actively engage in front-end development using HTML, CSS, JavaScript, and Bootstrap to deliver complete, full-stack solutions. When I'm not coding, you can find me tracking my fitness goals or exploring new creative tech ideas.
