2-4 Week Sprint
Idea-to-Prototype Sprint
Working software in 2-4 weeks. Built to grow into your MVP.
Working software, built by a senior engineer with agentic AI. Not by agentic AI alone. Fixed price, no surprises.
Fixed price, set once we scope it over email. A simpler build costs less, a more complex one more.
You have an idea. Maybe a sketch, maybe a Notion doc, maybe a voice memo. You want to see it actually work before you raise, hire, or commit to a roadmap. Most agencies quote $25K and three months. Vibe-coding shops will give you something that breaks the moment a real user touches it. Neither is what you actually need. You need a working prototype, built like real software, ready to demo and ready to grow.
In 2-4 weeks you walk away with a clickable working prototype on a live URL. Real auth. Real data. Two or three core flows you can demo to investors, partners, or users. The full GitHub repo is yours from day one, on a standard stack any engineer can maintain. Everything runs over email, so the project never waits on a meeting. I love this kind of work and I do it at this price because agents make it possible, not because I cut corners.
I built Fitly AI with this exact workflow: 52 AI tools behind a ten-layer orchestration engine, all in production. And because your prototype is real software on a standard stack, the Prototype-to-MVP Sprint continues on the same codebase instead of starting over. Read the Fitly case study.
How it breaks down
What happens
Scope, data model, and wireframes
We scope the prototype over email: feature list, user journeys, data model, wireframes. We agree on what is in this sprint and what is deferred to MVP. Prefer to talk it through? A Zoom works too.
Agents implement, I review and QA every build
Agents scaffold the application against the agreed scope. I review and QA every update, harden edge cases, and make every architecture and product call. You get regular progress updates over email so you can watch it come together.
UX pass, error handling, live URL
Final UX polish, error handling, mobile responsiveness. Deploy to a live URL you can share with investors and prospective users.
Live Zoom demo, GitHub transfer, what-next plan
A live demo over Zoom when it is done. Full GitHub access. A written what-next review covering what is working, what is missing, and where this could go next.
Deliverables
What you walk away with
Live deployed URL
A real URL anyone can click and try. Hosted on standard cloud infrastructure. Yours to share with investors, prospective users, or anyone you want to show the idea actually working.
Full GitHub repo, day one
You own the code from the moment we start. Standard stack: TypeScript, Next.js or Angular, Postgres. No proprietary platform. No vendor lock-in. Any senior engineer can pick this up and continue.
Two or three core user journeys
The flows that actually matter to your demo: signup, the main feature, one supporting flow. Built end-to-end so a user experiences the idea, not just sees screenshots of it.
Written what-next plan
A written summary of what shipped, what is working, what is missing, and where the prototype can go next, plus a live demo over Zoom to walk you through it. Everything you need to brief an investor, a teammate, or your next engineer.
Also included
- Real authentication so you can demo logged-in flows
- Database with a real schema, not just hardcoded mocks
- Responsive design that works on phone and desktop
- README and setup docs so any engineer can get the project running
- Written handoff summary with what-next recommendations
Who it's for
This sprint is built for
Inventors with an idea you have been turning over for months and want to see actually run
Solo founders without a technical co-founder who need a real prototype before raising or hiring
Product teams validating a new direction before committing engineering budget
Anyone who has been quoted $25K and a three-month timeline and wants a sane alternative
Sound like you? Email me what you're building and I'll come back with a written scope.
Email me about this sprintWhy this is fast
Agentic AI is the leverage
What used to take a 3-person team three months now takes one engineer plus agents in 2-4 weeks. Build speed went up roughly 100x. The real win is iteration speed: I can refactor and re-ship a feature inside a day, so we converge on what actually works fast.
What I do vs. what agents do: This is not vibe coding. It is my normal product development cycle (scope, design, build, review, harden, ship), executed at 100x build speed. I review and QA every update and build the agents produce before it ships. 25 years of judgment shapes every architecture call, edge case, and product trade-off.
AI stack used in this sprint
To get started quickly
What I need from you
- Your idea in any form: sketches, voice memos, notes, a Notion doc
- A short email thread to scope the prototype (a Zoom works too, if you prefer)
- Decision-maker availability so I can email or follow up quickly when blockers come up
- Any visual or brand references you have (skip this if you do not have any)
After the sprint
Two paths from here
Hand it off
You walk away with a working prototype, the GitHub repo, a written what-next plan, and a live demo over Zoom. Run user tests, show investors, decide what to do next. No retainer, no obligation.
Keep me on
Continue into the Prototype-to-MVP Sprint to take this to first paying users, or stay on with me as a Fractional CTO retainer for ongoing iteration on whatever ships next.
