Hi, I'm Calvin C. Chan 👋

Full-stack TypeScript & AI engineer building web apps, APIs, automated agents, and workflows.

I’ve spent 15+ years building software across the full stack — web and mobile apps, back-end systems, and the infrastructure that connects them. TypeScript has been my primary language throughout, and over time I’ve developed a strong bias for pragmatic, deployable solutions.

Today, I focus on AI-powered products and automation: agents that work on your behalf, workflows that run without hand-holding, and integrations that connect the tools you already use. Whether it’s a web app, a server, or an automated pipeline, I build things that are production-ready and fully deployable.

Available for freelance and contract work. If you need a senior engineer who can own a solution from design to deployment, let’s talk.
