About

My work spans architecture and hands-on engineering: modular frameworks and well-documented APIs, open-source platforms and developer tools, and the release pipelines and quality gates that keep large codebases healthy.

Much of it sits where trust matters, from decentralised identity, verifiable credentials and secure data sharing to fast, reliable applications that people depend on every day.

I also build the demonstrations, proofs of concept and documentation that help others understand a technology quickly and put it to use, and I have worked with organisations across trade, finance, energy and logistics.

Earlier in my career I built signal processing and data analysis software, and for more than a decade I ran my own company, designing and delivering web, desktop, mobile and e-commerce applications for clients.

With a background in human-computer interaction, I design software that is as easy to use as it is dependable to run.
