How it goes.
I work with a small number of clients at a time. That means you get my full attention, direct communication, and a site that actually reflects your business.
Understand
One call, a written brief, access to the codebase. I come back with a scoped plan, a price, and a start date — usually within 48 hours.
Build
Short feedback loops. You see a deploy preview every few days. No week-long dark rooms, no surprises at hand-off.
Ship
Code merged, measured, documented. I stay for two weeks after launch to keep the numbers honest.
Let's get
specific.
The fastest way in: book an audit. It gets me into your codebase in five days, with a report you can act on. Everything else grows from there.
