About · CV

I am Bella Kristóf. You talk to the person who writes the code.

A self-employed web developer. I build custom websites, back-office systems and automations for Hungarian small and medium-sized businesses.

I have been building with PHP since 2018. I worked on the backend of the mobile apps for Hungary's largest music festivals, the redesign of MUPA.hu and high-traffic systems for the Hungarian education sector. After that I spent almost four years in an international development team working on the e-commerce platform of a retail chain. Since August 2026 I have been working as a freelancer.

There is no project manager and no subcontractor: you talk to the person who plans, writes and launches the system – and who still knows every line of it after launch.

I work with Laravel, React and PostgreSQL, writing custom code without templates or plugins. That keeps the website fast, makes the internal system follow your processes exactly, and leaves it open to further development at any time.

If your website brings no inquiries, or daily admin takes too much of your time, let us look together at where you can gain the most.

      How I work05 / 05

      1. 01

        Business first, technology second

        I do not build a “modern website”; I build more inquiries, less admin and processes you can see through.

      2. 02

        Fixed price, clear schedule

        No hourly rate and no surprises after the quote. If the scope changes, we agree it up front.

      3. 03

        It stays yours

        Domain, code, data, access – all in your name. Portable at any time.

      4. 04

        Straight talk

        If a feature is not worth it, I say so. I only build what actually pays off for the business.

      Let us talk about your business.

      A free, no-strings conversation. No slides – concrete suggestions you can use even if you do not continue with me.
