About me

Full Stack Engineer with over 4 years of experience building scalable web applications on the MERN stack. I focus on backend architecture, middleware design, and production-grade systems that handle high-volume transactional workflows.

I design and implement robust APIs, business logic layers, and integration with third-party services. Experience includes complex pricing and markup systems, authentication flows, chunk-based data fetching, and query optimization—reducing API response times significantly in production. I use AWS (S3, CloudWatch, Lambda) to improve reliability and scalability, and I own the full development lifecycle from requirements to deployment.

I work with React and Next.js on the frontend and Node.js, Express, and Nest.js on the backend. My goal is clean architecture, maintainable code, and solutions that align technical execution with business goals. I am open to backend-heavy, scalable product, and international roles where I can contribute to system design and performance.
