Services

SaaS from 0 to 1

From concept to first paying customer. I build the whole product — auth, billing, admin area, deployment — not just the demo version.

The starting point

The real effort sits between a working demo and a product you’d trust with real customer data and real payments: tenant isolation, billing, access rights, an admin area, a deployment that doesn’t interrupt the service on every release. That’s exactly where small teams and solo founders need the most support.

How I approach it

  1. Product architecture first: design the data model and tenant isolation so it grows with real customers.

  2. Plan the payment provider and billing from the start, not bolted on afterwards.

  3. Zero-downtime deployment and monitoring from release one, so the first paying customer isn’t the first outage risk.

What you get

  • A complete product instead of a demo — including auth, billing, and an admin area.
  • An architecture that survives the jump from first test users to real paying customers without a rebuild.
  • A deployment process that allows releases without downtime from day one in production.

Frequently asked questions

Before you ask.

Does the product idea need to be fully worked out already?
No. A rough concept is enough for the initial call — the actual architecture and data-model decisions are part of the first project phase anyway, not a prerequisite for it.
Which payment providers do you support?
Usually Stripe or Paddle, depending on whether VAT handling for digital goods (Paddle as merchant of record) is relevant. I discuss the concrete choice in the initial call based on the product.
Do you also build just parts of a SaaS product, e.g. only billing?
Yes, provided the rest of the architecture already exists and is clean enough to build on — I’ll assess that honestly in the initial call, with a short audit beforehand if needed.
