Full-stack engineer building thoughtful systems across SaaS, logistics, and marketplaces.

Four-plus years of professional experience, with a focus on TypeScript, React, and Node.js — and a growing pull toward cloud infrastructure (AWS, Terraform) and AI-powered tooling. Recently, I've taken an interest in cutting down on unnecessary frameworks, packages, libraries, and abstractions while shipping lean, performant software that's easy to reason about.

How I work

I want to be the guy where, the whole time I'm on the team, things just run smooth and the hard parts never become anyone else's problem.

STILL WORKING ON ITSEE SYSTEMS
Current focus
  • 01Building and shipping RouteKing, my own SaaS.
  • 02Making the app I build at work genuinely easy to use, and faster to work in.
  • 03A Jira integration that lets non-engineers tag a ticket and have Claude Code research the codebase and help build the product.
