- Worked as the most experienced frontend engineer across 5 major frontend applications and 3 smaller products, owning complex features and contributing to architectural decisions.

- Maintained cross-browser compatibility and responsive/adaptive behavior across production applications.
- Introduced Playwright end-to-end testing into local workflows with Husky.
