SaaS products
A full-stack developer who builds the first version to last
Abdur Rehman is a full-stack developer who builds SaaS first versions meant to last: login and roles, per-customer data separation, Stripe billing, an admin panel and background jobs, with AI features where the product needs them. He has built FindRE, PropVPS, Scribeside and Crane Plan Pro this way.

This is for you if
- You have a validated idea and need a first version real customers can pay for.
- You want one engineer who can own it end to end: product, backend, billing and deployment.
- You have been burned by an MVP that had to be rewritten as soon as customers arrived.
What you get
The parts every SaaS needs
Login with roles and optional two-factor, data separated per customer account, and an admin panel for users, plans and settings.
Billing that works
Stripe subscriptions or credits with a customer portal, and webhooks that handle renewals, failures and cancellations properly.
Your core features
Built in small slices with a staging link after each one, so you test as we go instead of at the end.
Launched on your accounts
Deployed to Vercel, Railway or AWS on your domain, with handover docs and the code in your GitHub.
What should a SaaS MVP include?
Only what a paying customer needs to get the core value, plus the plumbing you cannot skip: secure login, data separated per customer, billing, and a way for you to manage users. Everything else waits until real customers ask for it.
Cutting features is fine. Cutting security, billing correctness or data separation is how MVPs get rewritten.
What tech stack do you use for a SaaS MVP?
Usually Next.js with Supabase or a Node.js and PostgreSQL backend, Stripe for billing and TypeScript throughout. It is a stack that ships fast, scales further than most startups ever need, and is easy to hire for later.
Can you add AI features to the MVP?
Yes. Summaries, chat, document extraction or an agent that acts on the user’s data, using Claude or OpenAI with usage limits and cost tracking, so your AI costs scale with revenue rather than ahead of it.
How do you hire a full-stack developer for a SaaS MVP?
Look for one person who can own the whole product: the interface, the backend, billing and deployment. For a first version that matters more than depth in any one layer, because the risky parts (payments, permissions, data separation) sit where the layers meet.
Then check the work rather than the résumé. Open a product they built and pay for something in it. Ask how they handle a failed renewal, a customer who must not see another customer’s data, and a job that takes longer than a web request allows. Give a short paid scope before a long one, and make sure the code and the accounts are yours from day one.
Hourly rates vary widely with seniority and region, which is why I quote a fixed price for an agreed scope instead of billing by the hour.
Where I’ve done this
PropVPS
Stripe subscriptions that trigger automatic server provisioning.
Scribeside
An AI medical scribe with two-factor login, audit logs and credit-based billing.
How it runs: Lift request, then Collision check, then Shareable plan.
Crane Plan Pro
Lift-planning software with a collision engine and PDF lift plans.
He has unfortunately ruined my standards for every other developer.
How a project goes
Scope the first version
We agree core features, user roles, plans and what launch looks like, in a short written scope.
Lay the foundation
Repository, database, login, roles and per-customer data separation.
Build in slices
Each core feature ships to staging for you to try and give feedback.
Billing, testing and launch
Stripe wired in, critical flows tested, then deployed on your domain with a handover.
Questions people ask
Straight answers. If yours is not here, ask me.
Ask me directlyI read and answer every message.Why Next.js and Supabase?
They let me ship fast without cutting corners: proper login, row-level security and a PostgreSQL database that grows with you. Most of my larger products run on a custom Node.js and PostgreSQL backend instead, and I build that when the product needs it.
What happens after launch?
You get handover docs and a walkthrough, and I am available for ongoing work on the next set of features.
What if my idea needs more than a first version covers?
Send me your feature list. I will suggest what belongs in the first version and what can wait, then quote that scope.
How does pricing work?
After a short call I send a fixed quote for an agreed scope, so you know the cost before work starts. Larger builds are split into milestones.
Do I own the code?
Yes. The code lives in your repository and runs on your accounts. You own the code, the accounts and the data, so you are never locked in to me.
