Internship Frontend Engineer resume example

• Under supervision, profiled a long results list in browser performance traces, separated network wait from rendering cost, and checked keyboard focus after virtualized rows were recycled.
• The team split the checkout bundle by route and replaced three blocking dependencies; I supported research preparation, validation, and documentation under mentor review. The team improved mobile LCP by removing the slowest step in the loading path; confirmed with my mentor that my contribution was limited to the assigned support and validation work.
• The team rebuilt form fields around shared semantics, focus states, and error messaging; I supported research preparation, validation, and documentation under mentor review. The team reduced repeat defects in the next release or review cycle; confirmed with my mentor that my contribution was limited to the assigned support and validation work.
• Under supervision, owned a React results-list improvement using browser profiles, reducing interaction latency from 240 to 130 ms on the same throttled device and fixture.
• Under supervision, released typed loading and error states in TypeScript, testing keyboard recovery and JavaScript network failures so users could retry without losing their query.

• In a mentor-reviewed simulation, built a React and TypeScript trace explorer with typed filter state and keyboard navigation; preserved the selected run when users moved between search results and detail views.
• As a second supervised exercise, improved user experience through performance profiling and browser testing: virtualized long trace lists and added regression checks for loading, empty, and error states on narrow screens.
• Under supervision, the team introduced visual regression coverage for 32 high-traffic component states; I supported research preparation, validation, and documentation under mentor review
• Built an isolated fixture with normal, malformed and interrupted inputs; recorded the expected response before running the implementation so failures were distinguishable from a changed assumption.
• Packaged the reproduction steps, configuration and regression tests with the project; checked the instructions from a clean environment and documented the unsupported cases instead of claiming production readiness.
• Owned the independent regression fixture using isolated inputs, resolved a failing edge case and released a reproducible test package with expected outputs.

• Published an independent technical note using the project’s before-and-after traces, explaining the failed assumption, regression coverage and cases the implementation does not support.
