Prototyping on your own code
Code Hackathon – 2 days
Two days to make real progress on a real issue within your own repository, with an expert coach for each team. Your teams leave with a prototype of their code and a methodology they can reuse starting the following Monday.
Price upon request, starting from €2,000 excluding VAT per day · Written proposal within 24 working hours, without obligation.
Work on your code, not on an exercise.
A code writer truly shines on a real-world project, complete with its history, conventions, and existing debt. The Hackathon lays the groundwork for your repositories and then advances a concrete topic: new feature, migration, test coverage, or internal tool.
