What is a Product Builder?
Not a freelance dev. Not a PM. Not a designer. Someone who takes your idea and turns it into a live product, solo.
Product scoping
I turn a vague idea into a shippable scope.
Technical architecture
Modern stack, pragmatic choices, controlled tech debt.
Design & UX
Clean interfaces, smooth user journeys.
Frontend + backend
All the code, from React components to serverless functions.
Deployment & infra
Shipping, monitoring, CI/CD, production-ready.
Fast iteration
AI-augmented, I deliver in days what used to take weeks.
10 years of production XP. AI-augmented. Three ways to work together ↓
