Founder & product builder — turning enterprise finance experience into focused AI products.
I build practical AI products for finance, delivery and everyday work — and I write about the systems, decisions and lessons behind them. The short version: deep enterprise experience turned into focused software. I spent 18 years inside large organizations building the systems that run cash, treasury and the financial close; now I turn the problems I kept meeting into small, sharp products.
What I'm building
- Delivery Sheet — turn vague leadership asks into clear, reviewable delivery decisions before your team commits.
- Listemizde — discover trustworthy local businesses through real community recommendations, not paid rankings.
Each product carries an honest status — see them all on the products page.
Where the expertise comes from
The edge isn't that I can build apps — plenty of people can. It's the 18 years behind them:
- SAP Treasury & Cash Management — TRM, One Exposure from Operations, liquidity items, bank statement integration and BCM.
- Corporate treasury architecture — how ERP, TMS, banks and market data fit together, and which system should own which data.
- Finance-systems delivery — turning vague demands into clear delivery decisions: intake, scope, UAT, cutover and governance.
How I build
Small, focused products from real operational problems — shipped fast with a solo stack (Nuxt, Supabase) and AI in the workflow, but never letting AI make the product decisions. I build in public and write down what works, what I killed, and why.
Writing
I publish practical, first-hand notes across three areas: finance systems (treasury management systems, SAP treasury, architecture), product & systems delivery, and building AI products. If that's your world, the newsletter sends one practical pattern, decision or build lesson every two weeks.
