I build the systems companies run on.
I take SaaS products from architecture to production — backend, frontend, integrations,
and the judgment to know which one matters this week.
Three systems, three different constraints. Each one has a full case study.
Invoicing infrastructure built for VeriFactu compliance, not around it — an append-only ledger designed to survive an audit.
NFC-based identity and networking, with the backend of a real SaaS platform: accounts, subscriptions, and analytics behind a single tap.
Workflow and document automation that removes hours of manual admin work — a rule engine separated from document generation.
Architecture before code. Business context before architecture. Every system I build has to survive contact with real data, real users, and real regulation — not just a demo.
