04 — Process
How a project actually runs.
01
Discovery
We talk through goals, audience, and constraints. I write a short scope doc you can sign off on before we start.
02
Design
Wireframe, then high-fidelity in Figma. Tight feedback loops so the visual direction is locked in before code.
03
Build
Production code from day one. Preview deploys per branch, daily updates, no surprise reveals at the end.
04
Ship
Launch, monitor, iterate. I stick around for a free support window and keep the docs updated for your team.
05 — FAQ
Common questions, answered.
Most landing pages ship in 2–3 weeks. Web apps and SaaS dashboards run 6–12 weeks depending on scope. I'll always give a clear timeline before we start.
06 — Let's build
Have a project?
Let's talk.
I take on a few projects each quarter. If yours sounds like a good fit, send a quick brief and I'll respond within 24 hours.
