Architecture. Applications. Consulting.
Trinio is my independent practice for software and enterprise architecture, privacy-first mobile applications, and consulting — identity, AI, and programmes that have to work in production.
Three pillars
The shape of the practice.
Architecture for software and the enterprise. Applications people actually use. Consulting that stays honest when delivery starts.
Software & enterprise
Target states, capability maps, application boundaries, and design authority — so programmes have somewhere to land. TOGAF and SEI as a language, not a paperwork ritual.
Products I still ship
Native iOS, Android, and Flutter. Local-first data, store-ready privacy, HealthKit and Watch where they earn their keep. Five apps on this site, from idea to listing.
Advice that has to land
Programme strategy and delivery, identity when it is the control plane, and AI — both as a tool in development and as a capability organisations have to adopt without the brochure.
Applications
Five apps. One practice.
Each product has its own site, with screenshots and store links. They share a local-first instinct: useful on the device, careful with data, and built without a social feed.
Blumelle
Local-first cycle tracking, daily check-ins, and calm insights. No account.

Independent, senior, and still in the code.
Trinio is a consulting and development practice. I have been in software since April 2006 — 20+ years across software development, architecture, applications, and consulting. I still ship the apps and take on architecture, identity, and AI work that needs a senior pair of hands, not a slide factory.
