Finstack

a platform for borderless money transfers, p2p payments, and crypto exchange. the most complex thing i'd built at the time, and the first project of mine that moved real money.

a client wanted one platform for global transfers, p2p payments, crypto exchange, and live rates.

supposed to be a one-month job, took two, real money moving through it meant no room for bugs.

taught me idempotency the hard way and what a difficult client relationship looks like up close.

there's a version of me before finstack and one after. the after version charges more.
