The operating model is consistent: structure the evidence, constrain the decision, surface the exception.
Not AI replacing control. AI operating inside control.
01 · intake & evidence
Extraction, classification, deterministic rules and exception handling — turning documents and inbox traffic into structured, reviewable work.
02 · judgement & control
Evidence-led decisions, period-end outputs and visible differences, with human control reserved for genuine exceptions.
03 · engineering discipline
Automation treated as software: versioned, testable, evaluated and released deliberately rather than edited live.
04 · delivery surface
Full-stack tools and dependable connections across APIs, data and interfaces — designed around outcomes people can verify.
Working software, public code and reusable automation — not a slideware portfolio.
AI product · live
Chat with your spreadsheets — with a verification layer that re-checks every number before it reaches a chart.
Tax product · live
Gross-to-net and tax-reserve planning for Dutch entrepreneurs, with legal-form comparisons, deductions and period-based estimates.
Agentic delivery · open source
Issue triage → implementation → gated review → CI repair → staged deploy. One architecture implemented for both Claude and OpenAI Codex.
Multi-asset platform · private
Cloudflare Consolidated Portfolio Manager — an access-gated system for holdings across asset classes, built with Hono, D1, Durable Objects and scheduled market feeds. The production proving ground for the actions templates.
