Systems that still make sense in year three.
I design and build line-of-business systems — the ledgers, the stock, the money — for companies that will live with them for a decade. Azure and .NET, mostly. Twenty years of it.
Data that holds
Ledgers that cannot be edited into disagreement
Distributed systems
Pipelines that survive the day they fall behind
Software people use
Refusals that say what to do next
Wagering data platform
Multi-brand wager pipelines, a double-entry ledger, and the back office over it
Reporting and BI platform
Many sources into one warehouse, and the models the business actually reports on
Navbharat Group
Four products — website, sales, warehouse, project controls — sold together or apart
Healthcare rostering
Multi-tenant, with a rules engine holding shift regulations and each worker's own constraints
Biometric site access
Access control across major UK construction sites, integrated with hardware from several manufacturers
