Delivered and integrated production features across multiple concurrent products: Bitselah (fintech with 2M+ users), Firmly (AI legal-tech), Homemade (e-commerce), and the Nerdbug corporate website. Owned key frontend and admin work for Bitselah, including a filterable, self-serve admin tool for transaction monitoring and financial reporting across multiple service lines (crypto trading, gift cards, bill payments, airtime).

Built user-facing interfaces for AI-generated legal research/document comparison while controlling how AI output is surfaced and preventing broken-feeling states during ongoing generation. Supported API contract alignment with backend engineers to avoid integration mismatches and improved reliability and performance across platform flows. Also built and integrated admin/buye

Took full ownership of a cross-platform e-commerce and social app across architecture, backend, and release, shipping to both the iOS App Store and Google Play Store. Diagnosed and fixed an iOS-specific scrolling performance regression by identifying animated image transitions running on the UI thread during scroll and removing the unnecessary animation while preserving normal rendering behavior.

Established a reliable physical-device iOS development and release workflow for Expo (EAS deve

Integrated REST APIs using React Query with caching and background refetch, writing unit and integration tests for components most prone to regressions. Extracted repeated UI patterns into a shared component library, reducing time for building new forms and data tables through reuse of tested components.
