I build payment systems, AI workflows, and products that make complicated work easier to handle. I like being close to the interface, the machinery underneath it, and the people who have to use and run it.
pstack for Codex — open-source agent workflow library for Codex. Install it, activate poteto-mode, get evidence back.
MoneyOS — bank payments, programmable assets, and settlement in one operable system.
ARYZE · in production · aryze.io
Exchange and market infrastructure — quote to settlement across venues, routes, and liquidity.
Developer platform and delivery — APIs, deployment automation, and recovery paths from change to running release.
Cadence — sprint planning for small teams that keeps ownership and change history visible.
Personal AI employee — saved progress, durable decisions, results checked before completion.
Digital sales systems — interactive product pages that explain complex technology and where it fits.
- Open finance and payments
- Stablecoin and programmable asset infrastructure
- Money and operations systems
- Agentic systems
- Product engineering
I start with the problem and look for a useful first version. Cut scope, reuse a foundation when it fits, keep the decisions understandable to the next person who has to run the result.
About these pages — said once.
