Full-stack & mobile engineer · Founder, Project Yoked LLC
Parker, CO · Open to select freelance and collaboration
I build end-to-end products: web and mobile clients, APIs, data layers, and the operational pieces around them (performance, caching, observability, deployment). I’ve been writing code for 15+ years and lead product engineering as CEO/Founder of Project Yoked LLC.
Focus areas
- Product-grade React and React Native / Expo applications
- FastAPI and Python backends, PostgreSQL, Redis, and pragmatic cloud usage (AWS, containers)
- Open source libraries where reusable pieces deserve a public home
