What I'm looking for

I'm looking for a front-end development role where I can build responsive React interfaces, collaborate in an Agile team, and deepen my experience with REST APIs, authentication, and modern deployment workflows.

I've built and deployed React applications including MOOSCLESPRO, a fitness tracking app with authentication, persistent data, personalized workout sessions, and volume calculations.

At TechIn, I developed responsive React interfaces from Figma designs in an Agile team, collaborating with frontend and backend developers on feature delivery and REST API integration.

My projects include budgeting and student-management applications using React, JavaScript, Node.js, Express.js, MongoDB, and REST APIs. I focus on reusable components, responsive interfaces, dynamic data, validation, and maintainable application logic.
