Websites and web apps for small and medium businesses

A website for your business, no middlemen.

I design and build websites and web apps for businesses. Throughout the project you talk directly to me, not to a salesperson or a subcontractor. You know the price and the deadline before we start.

01 — Packages

Choose the scope, know the price up front.

  • A

    One-page site

    A single page with your offer, contact details and a map. For a business that wants to be easy to find on Google.

  • C

    Web application

    Online booking, a client portal, a calculator or an internal tool. We agree on the scope together and I quote after a conversation.

02 — Process

From the first conversation to a live website.

  1. Conversation

    You tell me what your business does and what you need. I ask about your goals and budget.

  2. Quote

    You get the price and the deadline in writing before you pay anything. You pay half up front and half on delivery.

  3. Design and build

    Every two weeks I show progress on a preview, so you always know where the work stands.

  4. Launch

    I launch the site on your domain and show you how to edit the content yourself.

  5. Support

    For 30 days after launch I fix bugs and answer your questions.

03 — Experience

Experience from large projects, at the scale of your business.

Since 2021 I have built web applications for companies in more than seven countries, including ITV and Roche. For your project I choose technologies that fit your needs and budget, and I work on it just as carefully.

04 — Contact

Tell me what you need.

A few sentences are enough: what your business does and what the website should include. I will reply within 2 business days with questions or a first quote. The conversation is non-binding.

What does your business do and what should the website include?
