01Method
How I work
Up front, the plain facts: I work with AI tools. That is what makes small jobs affordable. Everything is still checked by hand, and every piece here carries its check note.
- 1
Clarify
You fill in a short request form. I write down what is to be made and name a fixed price and delivery time before I start.
- 2
Build
AI tools supply drafts and code. Selection, structure and decisions stay with me.
- 3
Check
I look at the result, count and test. The check note says what has been checked and what is still open.
- 4
Hand over
You receive the finished files with a short how-to. One or two rounds of revisions are included in the package, and the price stays fixed.

04Context
Plainly said
Concept projects
Every piece shown is a concept project for an invented company. There are no client logos, reviews or quotes here.
Use of AI
I use AI tools for drafts and code and say so in every offer. Whatever I could not check myself appears as “Still open” on the entry.
Check note
The note says what I looked at, counted or tested. It is not a promise for every environment: some files, for instance, have so far been opened in LibreOffice but not yet in Excel.
Your data
Your data stays with you. All I need is a small anonymised sample without personal data. Finished scripts run on your own computer.
