From the data model to production: the whole product.

Mobile apps, SaaS platforms and the integrations that hold them together. I do my best work when I come in before the architecture is settled.

I think first. Then I write code.

Before the first line, I sit down to understand what has to be solved. It sounds like lost time and it is the opposite: what gets decided in that hour saves the weeks it takes to pull apart something built blind.

I started programming in 2022. What has kept me going since is fairly unglamorous — good habits, reading, and a beach half an hour away when I need to switch off. I am looking for a company or projects where what I build actually gets used.

The real requirement

I push on a request until it makes sense. What someone asks for and what they need are rarely the same thing, and finding that out late means building the same screen twice.

route

A short plan

What gets built, in what order, and what stays out. I would rather argue about it in a document than in a pull request.

Consistency over intensity

A project does not get finished in bursts of energy, it gets finished with rhythm. Moving a little every day beats rescuing something on the last weekend.
