What I'm looking for

I’m seeking a hands-on engineering role building scalable web or mobile products, with strong DevOps practices, ownership of features, collaborative teams, and opportunities to influence architecture and ship impactful customer-facing systems.

I am a full-stack software developer with over a decade of hands-on experience building web, mobile and backend systems using C#, TypeScript, Node.js and modern front-end frameworks. I started learning programming as a child and progressed through an apprenticeship into senior development roles, contributing to production systems used by insurers, police forces and hospitality platforms.

I have a track record of owning large projects end-to-end — from single-handedly delivering major C# applications to designing a modern booking engine using React, GraphQL and serverless architecture. I value pragmatic DevOps practices, scalable architectures and shipping clean, testable code that reduces operational friction and improves business outcomes.
