Colby Leed

Summary

Full-stack software engineer with production experience delivering responsive web applications, protected backend APIs, third-party integrations, relational databases, and cloud deployments. Built a paid SvelteKit, Go, and PostgreSQL client platform end to end, and contributed across Node.js, React, MongoDB, AWS, and Stripe on a startup team.

What I'm looking for

I am particularly interested in backend-leaning and full-stack roles that involve APIs, integrations, data, and production systems.

If your team is building in that space, I would love to hear about it.
