26 years building software and infrastructure for organisations where failure was expensive - defence, banking, insurance, energy, commodities, healthcare and identity. Full-stack .NET and Azure, from database schema to cloud platform.
Systems I have built have processed £1B+ in financial remediation and served 700K+ patient records. As CTO of a startup I built the entire platform from scratch and scaled it to 1,500+ locations.
Today I build differently: I command a team of AI to do the heavy lifting while I own the decisions - what to ask, what to build, what ships. The judgment is the one I have spent 26 years sharpening; the pace is new.

You publish a step, the operator runs it on the far side, and the whole run comes back as a log with every line stamped in UTC. Go CLI, plain-bash station, and a relay that cannot read a byte of what it carries. heliograph.dbhq.uk
