I will build your saas mvp as a full stack web app with auth and database


About this gig
An MVP is not a smaller version of your product. It is the one workflow that proves someone will pay, built properly enough to survive the next six months.
Most MVPs fail on the second point. They demo well and then cannot be extended, because auth was bolted on and the database grew by accident.
WHAT YOU GET
- One product, deployed on your own domain and hosting
- Real auth with roles, not a shared password
- A database schema designed up front
- An admin view so you can see what users are actually doing
- The repo, a README and a walkthrough recording
STACK
Next.js and React on the front. Node or Python behind it. Postgres or Supabase. Deployed on Vercel, Railway or your own account.
BEFORE YOU ORDER
Send me the one thing your product must do. If you send me a feature list, I will send back the three features that matter and the reasons the rest can wait. That conversation is free and it is where most of the value is.
WHAT I DO NOT TAKE ON
- Marketplaces with escrow or payouts
- Anything trading, gambling or crypto
- Fixed-scope work with an unmovable deadline under two weeks
Send me details of the project you have in mind

FAQ
How long does an MVP really take?
Two to four weeks depending on package, and that is real rather than optimistic. Anyone quoting a full SaaS MVP in five days is either rebranding a template or about to miss the deadline. My dates are padded and I usually deliver early.
What exactly counts as one workflow?
The single path a user takes to get value: sign up, do the main thing, see the result. For a booking product that is search, book, confirm. Tell me yours and I will confirm in writing whether it fits Core before you order.
Do I own the code and can another developer take over?
Yes, entirely. You get the repo, a README and a recorded walkthrough specifically so a different developer can continue without me. Lock-in is not a business model I want.
Can you add payments and subscriptions?
Yes, on MVP plus billing. That covers Stripe checkout, the webhooks and the subscription states - trial, active, past due, cancelled - which is the part that usually breaks after launch.
What if I want changes halfway through?
Small changes are absorbed. Anything that changes the agreed scope gets quoted before I build it, never invoiced afterwards. You will always know the number in advance.
Will it scale when we grow?
It is built to carry your first few thousand users without rework. Beyond that you need infrastructure decisions that depend on real traffic patterns, and I will tell you what to watch for in the handover.
Can you work with a designer I already have?
Yes, and it makes the result better. Send Figma files and I build to them. If you have no designer I use a clean component library rather than inventing a design system on your budget.
What hosting will I need and what does it cost?
Vercel plus a Postgres or Supabase instance, usually free to about 25 dollars a month at launch. It goes on your own accounts so you are never locked to mine.
