Turning ideas into
scalable systems.

I'm a Full Stack Developer with hands-on experience building production-grade web applications using Java, Spring Boot, and React. I thrive at the intersection of backend architecture and frontend experience.

My background in Electrical Engineering gives me a rigorous problem-solving mindset — I approach every codebase like a circuit: every component must serve a purpose, and the system must be resilient under load.

During my internship at Infotact Solutions, I contributed to a full-stack platform integrating job board APIs (LinkedIn, Indeed, Glassdoor), built RESTful services, and collaborated in an Agile team delivering features on tight deadlines.
