For nine years I helped lead Square's Developer & Partner business, and the team behind it scaled the platform past $17B in annual revenue.
The record ↓Two decades leading developer platforms — at Square, a business the team grew past $17B; before that, the products behind Coyote's sale to UPS. Then the cost of turning an idea into working software fell to almost nothing. Strategy and building stopped being separate jobs. So I kept doing both.
Three roles — payments pricing and ML, the public platform, then a 200-person organization. The keynote was one day of it.

Helped lead Square's Developer & Partner business across three roles — from the payments-platform pricing & ML team, to the public Developer platform, to running the 200+ person organization behind a $17B+ product portfolio: public APIs & SDKs, the App Marketplace, developer monetization, and in-person & online payments.
Keynote speaker at Square Unboxed 2023, Square's developer & partner conference (keynote).
Built and led a 45-person product & engineering organization; delivered the web and mobile products that contributed to Coyote's $1.8B acquisition by UPS. Grew the first remote teams from 3 to 45 in two years.
Co-founded a software-engineering training non-profit whose 40+ graduates now work at Google, Palantir, Amazon, and Bloomberg.
Four issued patents in payments tokenization, interchange prediction, and logistics. Advisor to founders building early-stage product and payments companies.
Each of these I made solo, end to end, with AI coding tools — mostly on nights and weekends. Staying hands-on keeps me current on how software actually gets made.
The same kind of platform I helped run at Square — auth, webhooks, rate limits, logging, SDKs, a dashboard, and docs — rebuilt solo as a working prototype.

Consumer oximeters show a number and store nothing; clinical gear gives caregivers no live view and no usable record. ApneaWatch streams oxygen saturation over Bluetooth, watches through the night, and turns it into something a doctor can read.
