/// About me

Building systems that
scale & connect

I'm a Technical Program Manager with nearly two decades in mortgage and financial services technology. I specialize in enterprise integrations, API/middleware architecture, and SaaS platform delivery.

Most recently I managed the Exchange Service Network at Dark Matter Technologies — a SaaS integration backbone connecting hundreds of LOS clients to third-party vendors via REST & SOAP APIs, OAuth 2.0, and MISMO 3.4.

Outside enterprise work, I'm an indie developer building Fuerza Home Services — a bilingual on-demand marketplace for home trades in Texas — and AI Transparent Notes, a desktop productivity app.
