A three-month backend engagement on an AI voice product for a UK home-services marketplace — unfamiliar in-house tooling, ambiguous AI-generated data, and every piece of work documented as it landed.

Owned the frontend for a government internal management platform — built it from scratch with React and TypeScript, working directly with the design and backend teams.

Returned to YLD to work on a UK fintech client — migrated pages from Angular to Next.js in a multi-brand, multi-tenant architecture, and contributed to a Node.js GraphQL BFF.

Helped modernize Starkey's medical Salesforce platform — contributed to the migration to current standards and helped build a component-based Design System with LWC.

Led a team of three building AI-powered products — took a Travel AI Assistant from idea to a working MVP using OpenAI function calling and a Spring Boot / React stack.

Worked across four industries in two years — contributed to PCI-compliant payment systems, crypto wallet infrastructure, energy platforms, and an NFT marketplace.

Led a team building a collectibles grading platform — worked on computer vision for automated authentication and blockchain integration for provenance records.

Built the design system behind BOOKR's booking & CRM platform, working across web and mobile from a single codebase. I hold a stake in the company and still contribute to product and code.

Six years growing from frontend developer to Tech Lead of a five-person team — built a sports management platform that passed 10,000 users, and led the incremental AngularJS to React migration.
