Services

What you can order, what it costs and how long it takes.

Landing page

from €400
1–2 weeks

One page with one job: getting the visitor to act. Suited to a product, a service or an event, when you need to launch quickly and start collecting enquiries.

  • Design and build from scratch, not a template
  • Works down to a phone screen
  • Contact form with email notifications
  • Basic SEO: titles, descriptions, structured data
  • Deployed and connected to your domain

Web application

from €1200
from 4 weeks

When a page is not enough: user accounts, saved data, business logic. Calculators, dashboards, catalogues, booking and internal tools.

  • Sign-up, login and user accounts
  • Storing data and working with REST APIs
  • Interactive interfaces: boards, filters, calculators
  • Backend on Node.js or Python when needed
  • Deployment and full handover of the source code

    Tell me what you need. I ask about the goal, the audience and examples you like. Free and with no obligation.

    Fixed estimate

    You get the scope, the price and the deadline in writing. Nothing starts until you agree to them.

    Work in the open

    You see the result as it is built, not only at the end. Two rounds of revisions are included in the price.

  4. 04

    Launch

    I deploy the site, connect your domain and hand everything over. Fixes are free for 30 days after launch.
