Backend-Focused Full Stack Developer | Node.js | MongoDB | PostgreSQL | Scalable SaaS Systems

About

I work as a backend-focused full stack developer, building the core systems that power SaaS products. My primary focus is on designing and developing backend services, APIs, and data layers that handle real world scale and complexity. I work extensively with MongoDB and PostgreSQL, thinking through data modelling, query efficiency, and how systems behave under load. While I also contribute to frontend development using React, most of my work sits on the server side — building reliable APIs, managing data flow, and ensuring the system is structured in a way that is scalable and easy to extend. I enjoy working on data driven products where backend systems play a critical role in shaping performance, flexibility, and overall product experience.
