Configured Webpack & Rollup for specific bundling use cases (libraries, UI applications), transitioning from legacy Gulp/Grunt configurations for improved maintainability.

Wrote unit tests in react-testing-library (previously Enzyme) and advocated for Cypress for visual testing to bridge the gap between frontend and QA developers.

Improved overall testing DX by introducing better tools like MSW for API mocking.

Created frontend aspect of web applications for health care and mobility in ReactJS

Mentored junior developers and streamlined processes, defining application structure.
