I will build your full stack mvp web app for startups


About this gig
Ship your MVP in days, not months.
I build full-stack MVP web apps for founders and startups who need to validate an idea, pitch investors, or land the first paying customers fast. No bloated agencies, no 3-month timelines, no "we'll circle back next sprint."
What you get:
- A production-ready web app deployed on a live URL
- Clean React + TypeScript codebase you fully own (source code included)
- Authentication, database, and the core workflow that makes your product valuable
- Responsive design that works on desktop, tablet, and mobile
- A real product you can demo, share, and start collecting users on
Why founders pick this gig:
- Speed: 7 to 21 days from kickoff to live URL, depending on scope
- Modern stack: React, TypeScript, Tailwind, Supabase/Firebase the same stack YC startups ship on
- Founder-friendly: I've built dozens of MVPs. I know which corners to cut and which to protect
- You own everything: Full source code, no vendor lock-in, no monthly "platform fees"
Best fit for:
- Solo founders validating an idea
- Startups preparing for a demo day or investor meeting
- Product managers testing a new feature outside the main product
- Agencies who need a reliable technical partner

FAQ
How fast can you deliver?
Starter MVPs ship in 7 days, Growth in 14, SaaS-Ready in 21. Need it faster? Add the Extra Fast Delivery option and I'll prioritize your project.
What tech stack do you use?
React + TypeScript on the frontend, Tailwind for styling, Node.js/Next.js on the backend, and Supabase or Firebase for auth + database. Modern, fast, and easy for any developer to pick up later.
Do I own the code?
Yes. 100%. You get the full source code, deployed to your own GitHub repo and hosting account. No lock-in.
Can I add features later or hire another dev?
Absolutely. The codebase is clean, commented (on Standard/Premium), and uses industry-standard patterns. Any React developer can continue the work.
Do you handle deployment?
Yes — I deploy to Vercel or Netlify. If you want a custom domain connected, add the Deployment + Custom Domain extra.
What if I need changes after delivery?
Each package includes 1–3 rounds of revisions. Extra revisions are available as an add-on.
Do you sign NDAs?
Yes, happy to sign your NDA before we discuss details.
What do you need from me to start?
A short brief describing what your product does, who it's for, and the 3–5 core screens/features. A wireframe or reference app helps but isn't required.
Can you design it too, or do I need a designer?
I handle the design. It won't be a custom brand system, but it'll look clean, modern, and on par with any well-built SaaS product. If you have a designer, I can implement their Figma files.
What happens after the gig ends?
You get the deployed app, source code, and a handover message. For ongoing work, I offer retainer/maintenance outside of Fiverr — just ask.
