Colton Sweeney · Full Stack Engineer
I help businesses turn ideas into web apps and sites that load fast, work everywhere, and are built to last — shipped with the polish your customers notice and the quality your team can maintain.
Why work with me
POINT 01
I optimize for the numbers your business runs on — page speed, conversion, and search visibility — not just how the site looks in a demo.
POINT 02
You work directly with the person doing the work. Clear updates, honest timelines, and no handoffs that lose the details along the way.
POINT 03
I write typed, well-structured, documented code, so the site stays easy to change long after launch — whether I maintain it or your team does.
Selected work
01Most AI features on this site call a hosted API. ai.coltoncs.com is the opposite: a gated LLM and image-generation platform running entirely on a home PC I own and administer — two models served concurrently on a single RTX 3090, a chat interface, a ComfyUI image pipeline, and a Cloudflare Tunnel and Access policy that make it reachable from anywhere without opening a port.
02Raleigh's historic places were spread across separate preservation, National Register, and historic district datasets with no single public view. Open Raleigh is a map-first community archive of roughly 9,000 sites — including over 1,000 already demolished — with search, faceted filters, a moderated contribution workflow, and all of it republished under CC BY 4.0 through a documented public API.
