- Protect critical areas with tests
Ways to start
Code & architecture review
An independent look at code, architecture and delivery – with prioritized risks and concrete next steps.
A defined development package
A new application, a feature, an integration or the modernization of a clearly scoped area – even without an in-house development team.
Interim technical lead
Technical decisions, reviews and support for your team – until the responsibility is back in-house.
An extra engineer on your team
I work alongside your developers on the tasks ahead – with your tools and your processes.
