Summary

Experienced Front-End Developer with a proven track record in building responsive, high-performance, and user-centric interfaces using React and TypeScript. Skilled in developing components from scratch, as well as customizing and implementing MUI components to meet specific project needs. Proficient in managing complex data flows through RxJS and React Context API, enabling seamless user experiences across data-intensive applications. Experienced in utilizing Storybook to create and visually test components in isolation, ensuring a consistent, high-quality UI.

In addition to front-end expertise, I have a foundational understanding of back-end development with Node.js, as well as GraphQL for creating resolvers and schemas. Familiar with AWS infrastructure, used services into CI/CD pipelines. My exposure to backend and cloud technologies has sparked a strong interest in furthering skills in these areas.

I am seeking opportunities where i can evolve into a full-stack role, leveraging front-end strengths while building deeper expertise in backend development and cloud integration to create more comprehensive, end-to-end solutions.
