I'm a Product Engineer and a creative based in London. I’ve built full-stack applications across web, mobile, blockchain and embedded platforms. My client-side work includes React, Electron, Roku’s Scenegraph, and native iOS development with Swift and SwiftUI, always with a strong focus on UX and design-first thinking. On the service-side, I’ve worked with traditional service hosting, containers, and serverless, including (but not limited to) AWS, GCP, Cloudflare, Workers, CloudFormation, SAM CLI, nodejs, bunjs, MySQL, Postgres, NoSQL, grpc, Redis, Docker, nginx, and a few legacy tools best left unnamed (yes, including CodeIgniter and ftp).

I’ve also developed developer tools like CLIs and SDKs, primarily JavaScript land, and have written code in systems languages such as Rust and Zig.

In the AI space, I’ve integrated models via the OpenAI SDK, leveraged prompts, LLMs, and explored LangGraph.

I care about clean code, great UX, developer experience, documentation (yes), rapid iteration and automating workflows with CI/CD (GitHub Actions, Bash scripts, etc).
