About
I’m a senior full stack software engineer with 10+ years of experience building and maintaining enterprise applications across government, fintech, cybersecurity, and technology. I enjoy designing scalable frontend architecture, backend services, and data-intensive dashboards using modern TypeScript-based stacks.
Right now, I’m delivering full-stack engineering solutions for HMRC through Capgemini, including developing AI-powered workflow agents to support automation and improve engineering processes. I also lead technical design and code reviews, and I support colleagues through people management, regular check-ins, and performance reviews.
