Betfair & SkyBet
End-to-end full-stack development of high-traffic betting products for Betfair and SkyBet: interfaces in React and React Native, serverless services on Cloudflare Workers, and real-time integrations with the Betfair Exchange.
On the web (React 19 + TypeScript) I maintained and evolved core screens of the Betfair Predicts product — the MarketEventPage, HomePage, event carousels and the Stories system. On mobile (React Native, iOS/Android) I built and maintained accessible, high-performance cross-platform apps for both Betfair and SkyBet.
On the backend (Cloudflare Workers + Hono) I built market microservices with data normalization, integrated the Betfair APIs (ERO/LBR/CBR) and added edge caching with Cloudflare KV. Accessibility was a first-class concern throughout: strict WCAG compliance, full screen-reader support (VoiceOver/TalkBack), semantic labels, focus management and colour contrast.

- React Native apps (iOS/Android) for Betfair and SkyBet — accessible and high-performance.
- Cloudflare Workers + Hono microservices: Betfair API integration (ERO/LBR/CBR), data normalization and edge caching with KV.
- Strict WCAG accessibility: VoiceOver/TalkBack support, semantic labels, focus management and colour contrast.
- Testing with Vitest (unit) and Playwright (E2E); led production incident investigations.
