Owned the GraphQL backend-to-frontend stack enabling interactive AI experiences. Built proof-of-concept for collaborative AI agents handling multi-step workflows. • Concur Funds & Grants and Budget Modules – Led architecture and development of micro-frontend applications. Migrated legacy monolith to a cloud-native Lerna monorepo, improving code maintainability and developer productivity by 65%. Improved application performance by 45% through Lighthouse profiling, code-splitting, and caching strategies. • Ensured production-grade compliance with RBAC, secure cookies, HTTPS, input validation, and accessibility (WCAG, ARIA, semantic HTML, A11Y tools). • Set up CI/CD pipelines using AWS CodeBuild, Docker, and Kubernetes. Introduced monitoring with ELK and PagerDuty, reducing customer incidents by 40%. • Mentored 10+ engineers and collaborated with PMs, UX, localization, and accessibility teams to deliver end-to-end product features aligned with business goals. Previously worked at Altimetric, Tesco (Nineleaps), Covalent Capital, and Tech Crayons, contributing to platforms for Ticketmaster (Sponsorship), Novartis (Digital Data Platform), Tesco (Retail Cost Management), and a Fintech Bond Trading Platform. What sets me apart is a disciplined approach to software craftsmanship—grounded in clean, maintainable code, thoughtful architecture, and adherence to industry best practices. I prioritize writing code that is not just functional, but also scalable, testable, and easy to evolve. Whether it's implementing design patterns, enforcing code quality standards, or promoting team-wide consistency, I strive to build systems that stand the test of time.
