How it works

Three steps. No long process.

  1. 1

    Book a call

    Pick a time above. We spend 30 minutes on what you're building, the constraints, and whether we're the right fit.

  2. 2

    We scope it

    We send a short written proposal — fixed scope, timeline, and price. No surprises.

  3. 3

    Build & Ship

    You get regular updates to the process until we finish the code you own.

About

Hi, I'm Kolten.

I've spent the last 5 years shipping software, working solo with founders and small teams. I do the design and the engineering, so there's no hand-off gap and no telephone game.

I work with a small number of clients at a time so the person you talk to on the call is the person writing the code.

  • 5+ years building for the web
  • Design + full-stack in one person
  • Fixed scope, fixed price — no hourly billing
  • You own the code and accounts from day one
FAQ

Questions people ask on the call

How long does it take?

A brand-new project usually takes about two months from kickoff to launch. Smaller builds and add-ons move faster. You'll get a real timeline in the proposal before anything starts.

Who owns the code?

You do — from day one. Everything lives in your GitHub, your hosting, and your accounts. No lock-in and nothing held hostage.

Do you do ongoing work?

Yes — some clients keep me on a light monthly retainer for changes and new features after launch. Entirely optional.

What if we're not a fit?

Then I'll say so on the call and point you somewhere better. The 30 minutes is free either way.
