I am a Senior Full-Stack Engineer with over 20 years of experience delivering enterprise-grade solutions across government, healthcare, logistics, education, and IT consulting. Starting as a PHP/MySQL developer in 2003, I’ve since built large-scale systems for organizations such as HCL Technologies, DHL, the UK’s NHS (National Health Service), and DWP (Department for Work & Pensions). My strengths include architecting scalable microservices using Java, Node.js and TypeScript with extensive experience in NestJS, Hono, Spring Boot, and modern REST API design. I enjoy working with Serverless and Edge Computing-based technologies - ultimately Deno Deploy with PostgreSQL (NeonDB). I also excel in React, accessibility, responsive design, and component-driven UI development. I enjoy solving complex challenges, modernizing legacy systems, and delivering future-ready solutions. I am committed to lifelong technical learning. I proactively explore emerging technologies and frameworks to identify and implement optimal solutions.​
