Each stage answers one question. Start at the one your idea is at.
| Stage | Answers | What It Is | The Code |
|---|---|---|---|
| Proof of Concept | Can it be built? | What it is: The riskiest part, working, in one week | The code: Throwaway: it answers one question |
| Prototype | Does it make sense to users? | What it is: The core flow, clickable, in one week | The code: Throwaway: it answers one question |
| MVP | Will people pay? | What it is: Sign-in, payments and the core feature, launched in six weeks | The code: Becomes the product |
| Full Build | What do users need next? | What it is: Launch, then week by week on feedback | The code: Grows with the users |
Some sell an "MVP in six days": that's a prototype at MVP prices.
One task at a time, toward real users in week 6.
The core feature, clickable on a live link
Sign-in, data and payments, one task at a time
Edge cases and errors handled, live for real users
Keep building on feedback, pause, or hand over
Long enough to launch something real, short enough to stay small.
| Rule | What It Means | Principle |
|---|---|---|
| Fixed Time | Six weeks is the budget; the scope shrinks to fit | Principle: Appetite, Not Estimates |
| The Core First | The one job users pay for gets built first | Principle: Find the Core |
| Live Is Done | Done means real users on it, not a demo | Principle: Production Is Done |
Founders who know the problem and need the build, not a co-founder.

A simple, predictable and transparent process that eliminates development headaches.
After subscribing, you get a dedicated task board. It becomes your roadmap.
Week one: the core flow, on the real stack and a live link.
You set the priorities. I build the MVP on it, one task at a time.
You review working software every few days. I revise until you approve.
You approve finished work. Week six goes to edge cases and the launch.
You report issues anytime; I handle them first.





One weekly price: six weeks to launch is $5,982, paid weekly. No quote, no equity.
A senior developer for your first version, without agency overhead.
$997 a week: six weeks to launch is $5,982, paid weekly. Stop after any week. The free build cost tool sizes your scope in weeks.
Six weeks, with the scope cut to fit: the smallest real product. The core flow comes first, in week 1.
Only when the risk is technical, like an AI result or an integration. Then a one-week proof of concept answers it first.
Find ten people who have the problem and would pay to solve it, then name the core feature in one sentence. The free lean canvas and feature priorities tools help.
No. I make the technical calls and explain the trade-offs in plain words.
JavaScript and TypeScript on the default stack: React, Next.js, Node.js, Firebase. On phones, usually as a PWA, installed from the browser.
You do: the code, the accounts and the keys are yours from day one, and so is your equity.
Work that isn't right, I revise until you're satisfied. Or cancel after any week, with no penalty.
The retainer carries on as SaaS development: each week builds on what users do. Or pause, or hand the code over.
Fill in the project form, about a minute. I reply the next working day; if it fits, with a first plan and a call invite.

MVP Development fits founders best: people building a product without a technical co-founder.
“No one makes the technical calls”: the calls and the code, every week.
“An idea nobody has clicked”: the core flow on a live link in one week, one payment.
MVP Development
“An idea, ready to test with paying users”: the smallest real product, launched in week 6.
“Ready to build the whole product”: launched in week 6, then built on real feedback.
“Phones, without three separate apps”: one app that installs from a link.
“An app stuck, unsafe, or left by its developer”: the bleeding stopped and a plan, in one paid week.
“A V1 that holds the product back”: V2 built beside it, until every user moves.
“A raise or a purchase on the calendar”: what diligence will find, ranked, in one paid week.
