Weeks, not months.

My process is built for speed without cutting corners.

1

Scope

Define the product, map the architecture, identify the MVP core. 2-3 days.

2

Build

Design, develop, and integrate. Backend, frontend, AI, automations — in parallel. 2-4 weeks.

3

Ship

Deploy to production, set up monitoring, launch. You get a live product, not a prototype.
