I build custom web applications and automation systems that save teams time and ship fast.

Over the past decade I've worked across the full stack — from architecting backends and data layers to polished React frontends — including engineering work at Contra itself, where I built search and payments features used by hundreds of thousands of freelancers.

What I do best:

• Custom app development — taking products from idea to production with Node.js, TypeScript, React, and Next.js
• AI & workflow automation — LLM integrations, AI agents, and automations that eliminate repetitive work and connect your tools
• Full-stack engineering — APIs, databases, integrations, deployments, and the architecture decisions that keep them maintainable

I work directly with founders and teams, communicate clearly, and deliver production-quality code — not prototypes that fall over. Based in Calgary, Canada, working with clients worldwide.
