I’m a senior front-end engineer specialising in React, TypeScript, and modern JavaScript, with extensive experience delivering high-traffic, accessible, and performant web applications for organisations including the Premier League, the British Film Institute, and Argos.

I build scalable, maintainable front-end architectures, working across both server-rendered and SPA environments. My work spans greenfield builds, large-scale rebrands, and monolith migrations, often modernising legacy systems and introducing clear component patterns, design-system alignment, and predictable development workflows.

My technical strengths include:
  1. React + TypeScript, modular component libraries, and design systems
  2. Modern CSS (grid/flex, BEM, CSS Modules, Styled Components)
  3. Performance optimisation (Lighthouse audits, WebP adoption, JS/CSS refinement)
  4. Accessibility (WCAG 2.0/2.1, NVDA/VoiceOver, DevTools auditing)
  5. SSR, API integration, and front-end build pipelines (Webpack, CI/CD, Docker Dev Containers)
  6. Pragmatic testing with Jest, React Testing Library, Cypress, and BDD
  7. Clear technical documentation and onboarding guides for smooth handover

I work closely with Product, UX, and back-end engineers to maintain delivery momentum, defining API contracts early, using mocked data to progress features in parallel, and ensuring predictable behaviour across environments.

Recent projects include secure, high-traffic React features, IP-restricted access flows, inactivity detection, and scenario-testing dashboards, which help to accelerate the QA process and stakeholder sign-off.

I focus on writing clean, maintainable code and delivering front-end solutions that are robust, accessible, and scalable.
