Booking systems and web apps that hold up in real use.
I’m Daniel, a React and TypeScript developer in Brașov, Romania. I build the whole thing: the booking flow, the payments, the admin screen and the tests that keep them honest. I work in English, German and Romanian.

How a project runs
You describe the job
Through the inquiry form or by e-mail. A short call is usually enough to understand it.
You get a written plan
What I will build, how long it takes and what it costs, before any work starts.
You see it working early
A preview link you can open on your phone, not screenshots. Your feedback goes into the next version.
Launch and handover
Tested on phones and with a keyboard, hosted on accounts in your name, with notes on how to run it.
For hiring teams
I’m looking for a role building React and Firebase apps. The quickest way to judge my work is the code behind this site: the security rules, their tests and the CI that runs them.
I work with AI coding tools, Claude Code among them, and I own what ships: the plan, the review and the tests.

About
I live in Brașov. German and Romanian are my native languages, and I work in English every day. I study at Politehnica Bucharest, in the German-language stream.
I care about the parts people don’t see: what happens when two customers book at once, when a payment arrives late, when someone uses a screen reader. I also founded GoActive Bucharest, a youth group that runs Erasmus+ exchanges, and built its website.
