Portfolio.

Two years of merged PRs across the Open edX enterprise stack — LMS/HRIS integration resilience (Canvas, Moodle, Degreed, Cornerstone, Blackboard), a system-wide provisioning-admin role and RBAC migration, learner-credit request endpoints with Braze triggers, SSO/SAML cleanups, and catalog filtering improvements.

Led seven engineers on the React Native app for the largest US blue-collar jobs platform. Took rendering from 20fps to 50+fps, upgraded RN 0.64 → 0.68, and shipped user-connection features behind LaunchDarkly. Added Detox + GitLab pipelines on a custom runner.

Set up TypeScript for freeCodeCamp's new UI component library — sample components, stories, and Jest config updates to support TS end-to-end.

Shipped a private, easy-to-use mobile app for earning, learning, spending, and saving Bitcoin. Built from mockups to responsive UI, wired up APIs, and added Detox end-to-end coverage. Referred from a previous client (Sifir.io).

Designed and coded an open-source Bitcoin wallet in React Native. Optimized animations with D3.js to keep the bridge lean, built privacy/anonymity options, and reworked UX for mobile-first accessibility. The owner doubled my rate twice in a week.
