How I work
From quote to deploy.
Four steps, no hidden stage. You know what happens, when, and what it costs before I write the first line.
Conversation
You tell me the problem (or send a link to what exists). Within 24 business hours I come back with questions or a proposal.
Fixed proposal
Scope, deadline and price in writing within 3 business days. No surprises on the invoice.
Build with preview
You follow along on a preview URL. Adjustments happen during the build, not after.
Deploy + 3 months
Live on your domain, code in your GitHub, invoice issued, and 3 months of adjustments included.
You get
- fixed scope
- a deadline
- code in your repository
- contract and invoice
- 3 months of adjustments
