About Me

I’m a Computer Science Engineering student focused on backend and full-stack development using the JavaScript ecosystem. I build structured, maintainable systems with Node.js, Express, and MongoDB, emphasizing clean API design, authentication workflows, and efficient database modeling.

My work centers on solving practical engineering problems — from implementing secure authentication flows to building automation-driven systems and dashboard-based applications. I care about writing predictable, scalable backend logic rather than just making features work.

Currently, I’m deepening my understanding of backend architecture patterns, API optimization, and deployment workflows to build production-ready systems.
