Leading a team of 8 engineers to build crypto accounting and tax products across consumers and enterprises. Day-to-day, I touch every part of the stack, lead technical decisions, and make product decisions.

Current Project:

Leading and building an embedded crypto tax solution inside of the top crypto exchanges.

Completed Projects:

• Architected and implemented our next generation app architecture. Led to over 4x speed up in page load times. 3x increase in developer velocity. https://www.cointracker.io/blog/introducing-cointracker-2-0

• Old architecture: one app with a tightly coupled backend/frontend architecture built with Python and Jinja

• New architecture: decoupled GraphQL API server in Google Cloud, multiple React web apps running on the edge in Cloudflare, a monorepo hosting all client apps (consumer web and mobile app, enterprise web app, marketing apps).

• Built a enterprise subledger for crypto accounting from 0 -> 1 in 4 months. Led product decisions and engineering. https://www.cointracker.io/blog/cointracker-enterprise

• Add wallets flow in mobile. Used by 60% of our users.

• Rebuilt Auth flow in mobile app.

• Handle DDOS attacks and security attacks on the edge and application layer.
