About me

Understand the whole system before changing it

I work best when I can connect the functional problem with the code, infrastructure and day-to-day operations.

Maintainability over shortcuts

I prioritise clear, automated solutions designed to evolve without adding fragility.

Control before execution

I value safety, validation and reversibility, especially in automation and changes to live systems.

Progressive modernisation

I have experience with existing systems, migrations and incremental improvements that reduce risk.

AI when it adds value

I integrate models through APIs to solve specific needs, with structured validation and fallback mechanisms.
