For founders with a product to launch

You have an idea you've tested with real people, a budget and a date in mind. What you need now is a first version people can sign up for and pay for, built so it doesn't have to be thrown away six months later. That's what I build, as a senior full-stack developer with 15+ years of shipping web products.

You work with me directly. The person on the scoping call is the person writing the code, so decisions don't get lost between account managers and developers. If you already have a prototype made with an AI tool, start with AI prototype to production instead. If your product is about bookings or connecting buyers with sellers, see booking and marketplace platforms.

Scope first, then code

Most MVPs run over budget because the first release tries to do everything. Before any code, we agree on the smallest set of flows that proves the business: who signs up, what they do in the first session, and what they pay for. Everything else goes on a list for later, with a rough price next to each item.

Then I build on a stack that will carry you well past launch:

  • Nuxt and Vue on the front end, server-rendered where it helps SEO
  • Laravel and PostgreSQL, or Supabase when the product is simpler and speed matters most
  • Stripe for subscriptions, trials, invoices and plan changes
  • Tests on the flows that make money: sign-up, checkout and the core feature

You see working software on a staging site every week, so you can change priorities while it's still cheap to do so.

Proof

  • WithMaslow: a personality assessment platform with teams, social login, one-time-code sign-in and AI-generated insights.
  • CautElectrician.ro: a directory with public profiles, quote requests and moderated testimonials, built on Nuxt 4 and Supabase.
  • Smiles Casino: full-stack work on the player site of a US social sweepstakes casino, with a coin store, identity verification and prize redemptions.

What affects the price

SaaS MVP projects start from €9,000; you get a fixed quote after a short scoping call. The main factors are the number of user roles, how complex billing is, integrations with other systems, and whether you need AI features from day one.

Let's scope your first release

Send me a short description of the product, who it's for and when you'd like to launch. I reply within one working day, and after a short call you get a written proposal with scope, timeline and a fixed price. Get a quote for your MVP.

How we work

  1. 1

    Scoping call

    We go through your idea, users and budget, and cut the first release down to what proves the business.

  2. 2

    Written proposal

    You get the scope, a fixed price, a timeline and the stack in writing, before you commit to anything.

  3. 3

    Build with weekly demos

    Every week you see working software on a staging site and can change priorities before they get expensive.

  4. 4

    Launch and next steps

    I deploy, hand over the code and documentation, and stay on for fixes and the next features if you want.

Frequently asked questions

How much does it cost to build a SaaS MVP?

A focused SaaS MVP starts from €9,000, which covers accounts, Stripe billing, the core feature set and an admin area. Products with more user roles, integrations or AI features cost more. You get a fixed price in a written proposal after a short scoping call.

How long does it take to build an MVP?

Usually between six and twelve weeks from the signed proposal to launch. Scope decides it more than anything else, which is why the proposal lists exactly what ships in the first release and what waits for later.

Should I hire a freelancer or an agency to build my MVP?

With me, the person on the scoping call is the person who writes the code, so nothing gets lost between sales, project managers and developers. An agency makes sense when you need designers, several developers and a project manager at the same time. I can also work alongside your designer or an agency if you already have one.

Which tech stack do you use for SaaS products?

Usually Nuxt and Vue on the front end with Laravel and PostgreSQL behind them, or Supabase when the product is simpler and speed matters most. Both are mainstream, well documented and easy to hire for later. If your team already works in React or Next.js, I can build in that instead.

Will I own the code of my MVP?

Yes. The code lives in your repository from day one and you own it. I am happy to sign an NDA before the scoping call, and you get documentation so another developer can take over if needed.

Can you add AI features to my MVP?

Yes. Features such as generated summaries, insights or an assistant can be part of the first release or come right after launch. On WithMaslow I added AI-generated insights with Laravel AI and Gemini to the Laravel 13 API.
