EXPERIENCE

Innovatrics (Biometric), Frontend Engineer Oct 2024 - Present
Optimized a performance-critical identity verification flow (capture => validation => result) by
reducing redundant GraphQL requests by ~33%, improving TanStack Query caching, and
eliminating unnecessary re-renders, accelerating data load time from 4.1s to 3.2s (~21%).
Refactored a legacy biometric UI used across 4 production applications into a modular React
component architecture within a shared monorepo, eliminating cross-module duplication and
improving maintainability.
Contributed to the development of a biometric identity verification platform that processed 83M+
successful verification requests within the first two months of production.
Collaborated with QA to redesign the Playwright E2E test architecture across three production
applications in a shared monorepo, introducing shared fixtures and reusable helpers that reduced CI
test runtime from 1h17m to 53m (~31%) and improved test reliability and maintainability.
Designed a shared frontend verification package used across multiple applications, standardizing
domain logic and reducing duplicated implementation across teams.
