About · Budapest

One engineer, end to end.

Trained in mechatronics, shipping software since 2015: flight simulators, an investment bank, rail freight, education, e-commerce and art fairs. I'd rather own a problem end to end than hand it off.

Cerberus Technologies is my company, not an agency. The person on your first call writes the code, runs the pipeline and answers for production.

How I operate

Four habits you can count on.

    1. Scope in writing first

      Constraints and success criteria are agreed in writing before any code.

    2. Smallest design that works

      Architecture sized to the need, not to my CV.

    1. CI from day one

      Tests, pipelines and infrastructure as code from the first commit.

    2. You keep everything

      Code, IaC, monitoring and docs stay operable after I leave.
