Owen Eldridge

I’m a full-stack engineer working on money in regulated industries: payments infrastructure, and now pharmacy claims.

Most of my work is about correctness in money and claims data. I establish what the data supports, find where it stopped being true, and say clearly what hasn’t been measured yet. I came up through the operations side of consumer finance before I wrote software for a living, so I knew what the numbers meant before I built the systems that carry them.

I write Go, TypeScript, and a lot of SQL at work, and run my own homelab outside it.

Off by 36.00, and 36 divides by 9: the usual sign of two swapped digits. Wednesday was keyed as 1,240.00 instead of 1,204.00.
