Why FullDo

A SaaS is not just a website with a login

Recurring billing, account management, roles, security, availability, scalability: a solid SaaS needs a real architecture. I build a sound foundation from the start to avoid the technical debt that kills young products.

Solid architecture

A foundation designed to evolve, add features and support growth without rewriting everything.

Built-in subscriptions

Recurring billing, trials, pricing plans: monetisation from the design stage.

Security & availability

Accounts, roles, protected data and an infrastructure that holds up under load.

What I deliver

From idea to profitable product

01.

Scoping & MVP

I turn your idea into a first useful version you can launch quickly, to test the market without building everything at once.
02.

Accounts, roles & subscriptions

Sign-up, user areas, role management and recurring billing through Stripe: the heart of a SaaS.
03.

Dashboards & features

The business core of your product: the features that genuinely bring value to your users.

I grow the product at the pace of your customers: performance, new features, reliability.

Your questions

Clearing up any remaining doubts

A question that is not here? Write to me — a quick reply, from the person who will build your project.

An MVP (minimum viable product) is a first version that includes just the essentials to be useful and tested by real users. Starting there limits risk and budget: the market is validated before investing in every feature.

It depends heavily on the scope. I first price an MVP at a controlled cost, then further developments in stages. A free first conversation lets us scope a realistic range.

Through proven solutions such as Stripe: monthly or annual plans, free trials, secure payment and automatic invoicing. I configure whatever fits your model.

Yes, it is planned for from the design stage. I build a scalable architecture and scale the infrastructure as you grow.

You do, entirely. You keep ownership of the source code and your data. No forced dependency: I can support you over time, by choice rather than by constraint.
