What I'm looking for

I’m looking for a backend role where I can design scalable, maintainable systems and build secure RESTful APIs using Node.js, Express.js, and MongoDB—growing through real product impact and strong engineering practices.

I’m a dedicated Backend Developer focused on building robust, efficient backend solutions that power modern web applications. I specialize in Node.js, Express.js, and MongoDB, and I enjoy solving real-world problems through clean and scalable code.

Across my projects, I’ve developed e-commerce backends with user authentication, product management, cart and order processing, and payment integration—using JWT for secure access and REST API design throughout. I also build secure checkout and review flows, with an emphasis on maintainable system architecture, database modeling and optimization, and performance problem-solving.
