What I'm looking for

I seek a role where I can build scalable microservices and distributed systems, work in agile teams, take end-to-end ownership, and grow in infrastructure and reliability engineering.

I am a full-stack software developer experienced in designing and delivering reliable, scalable systems, with hands-on work across React.js, Angular, Spring Boot and microservices. I take end-to-end ownership of projects—from architecture and implementation to testing and deployment—focusing on engineering rigor, maintainability, and secure coding practices.

During internships I built production-grade applications including a full-stack File Manager and a Hospital Appointment Management system, optimized backend operations for performance, and delivered an AI pipeline for MRI brain tumor detection achieving over 95% accuracy. I thrive in collaborative, agile teams and seek to apply my skills to build high-performance infrastructure and distributed systems.
