How I work

From the first question
to the running system.

01

Get close to the workflow

Talk to the people doing the work. Map the constraint, the data and what a useful result would look like.

02

Build the right system

Choose the smallest useful architecture: an API integration, a constrained voice flow, or agents with clear responsibilities and approval gates.

03

Deploy, observe, improve

Handle the edge cases. Make failures visible. Keep human escalation available, and iterate with the users.

Builder. Founder. Operator.

I’ve been on both sides
of the requirements document.

Co-founding CADEMA at sixteen put me close to buyers, quotations and fulfilment. Building the systems behind it taught me to connect technical choices to commercial reality. I use Claude Code and AI-assisted Python and TypeScript workflows, with architecture, integration and operational ownership as my contribution.

About my background ↗
Employment & collaboration

Looking for a builder
who understands operations?

Remote roles are my first preference. Based in Hungary, I can also work on-site in Hungary with English-speaking teams. I do not speak Hungarian.
