Independent product engineering
Software for the parts that have to be right the first time.
Key custody, ledger settlement, and review workflows that carry legal weight. I design and build them, and most of it ships as software other people put their name on.
Selected work
What I do
01
Product engineering
Architecture through release, including the parts nobody demos: migrations, auth, audit trails, the release itself.
02
Cryptography and ledgers
Key custody, signing ceremonies, XRPL integration, and the security review that has to happen before any of it is live.
03
Review and rescue
I read an existing codebase and tell you in writing what will break, what it will cost, and what I would do first.
Writing
Notes on custody, ledgers and shipping, published on Medium. Read them here.
Have something that has to be right?
Tell me what it is and what is at stake. If it is not a fit I will say so and point you somewhere better.
