Every page is optimised to load fast even on mobile, where most visits happen.
Direct communication
No middlemen: you talk to the person writing the code and receive clear updates throughout the project.
Careful design
Tidy interfaces, clear hierarchies and attention to detail: form always follows function.

How it works
Five steps, zero surprises
01
Listening
We start with a call: goals, audience, constraints and budget. If the project doesn’t make sense, I’ll tell you straight away.
02
Proposal
You receive a clear proposal with scope, timelines and cost. No hidden items and no surprise quotes.
03
Design
We define structure and interface. You see the project before a single line of final code is written.
04
Development
I build the project in verifiable blocks, with online previews so you can follow progress step by step.
05
Launch and support
Publishing, final checks and assistance in the following weeks, to start off on the right foot.
Frequently asked questions
The answers you need before starting
It depends on complexity. A custom showcase website starts at €800, a structured backend or web application at €800-1,000, technical SEO at €400. For a tailored quote, write to me: you’ll get a first assessment within 1-2 working days.
A simple website takes 2-4 weeks. A structured web application takes 6-12 weeks. We define the exact timeline together in the proposal, with milestones and planned reviews.
Absolutely. You don’t need to know what a database or an API is. I translate your needs into technical solutions. You only need to know what you want to achieve.
I offer monthly maintenance plans from €50 to €100 that include security updates, backups, monitoring and email support. Larger changes are agreed as a separate piece of work.
Yes. I work iteratively and frequent updates are part of the process. Minor changes are included; significant changes are agreed together.
TypeScript, Node.js, C# with ASP.NET Core, React, Next.js, PostgreSQL, MongoDB, Docker and Git. I choose the stack based on the project, without imposing unnecessary technologies.
It depends on the current schedule. For urgent work we agree timelines and cost before starting, without promising deadlines I can’t meet.
