Rebuilt the consultancy’s UI approach across multiple client engagements by taking ownership of frontend architecture. Standardised the stack on React, Next.js, and TypeScript, and delivered a shared component library with centralized design tokens to prevent per-client UI rebuild cycles. Shipped three production frontends on tight timelines and improved performance (LCP from 3.4s to 1.2s) using Next.js SSR/SSG while ensuring Core Web Vitals. Implemented WCAG 2.2 AA patterns across shipped components and integrated OpenAI/Anthropic workflows into React interfaces and Node.js services. Owned client communication, scoping, and estimation from discovery through release.

Owned the React/TypeScript/Redux frontend of a maritime and green technology analytics platform. Reduced dashboard load/render time from 8s to 2.8s through memoisation, list virtualisation, and selective re-rendering for 50,000+ records. Redesigned UI architecture using React Hooks, Redux Toolkit, Material UI, and Tailwind CSS with conventions adopted across multiple modules. Built Playwright and Selenium test suites from scratch, growing coverage to ~60% and cutting production defects by roughly half, and extended automation to backend REST API contracts. Containerised the system with Docker and implemented CI/CD via GitHub Actions, replacing manual releases with automated daily deployments. Refactored legacy frontend modules to TypeScript to reduce runtime type errors.

Built single-page applications for multiple clients using React and Vue.js, often handling up to six concurrent projects. Developed reusable responsive component libraries with Tailwind CSS, Bootstrap, and Material Design. Designed and implemented 40+ REST endpoints and supporting data models across Node.js/Express and other backend stacks, and integrated AWS services for hosting and deployment across client projects. Translated design and business requirements into production implementations with stakeholders and cross-functional teams.
