At Pet Media Group, I designed and shipped a PIN-verified reservation and Stripe payment flow across the Node.js/GraphQL backend, Next.js, and React Native clients. I also contributed to the core payment platform, including checkout, pricing API migration, and refund improvements across six markets.
At Orthogonality Ltd, I delivered products for Cambridge University Press & Assessment, building AWS Lambda APIs and React Native interfaces for Sparkle and backend services for DYL. I also built a production MCP server and internal Claude Code skills at Pet Media Group, and created Versous, a Go-based product sentiment comparison tool and MCP server.
