At Outsource Global, I design and implement backend services with NestJS and Node.js. I’ve optimized PostgreSQL APIs with indexing and query tuning, and implemented cursor-based pagination for data-heavy endpoints.

At Kurio Technologies, I built and shipped a client application that helped schools monitor teacher performance and collect student feedback. As the sole engineer on the project, I developed its Vue.js frontend and Node.js services, and improved load times and responsiveness.
