Why & How

Use this app to customize your Cyberpunk 2077 experience and immersion.

It modifies the game configuration files for player movement & other gameplay characteristics.


I build this app entirely using test driven development, since the first code line.

A huge advantage, shown almost immediately, when having to re-design the architecture due to additional unexpected complex customisations.

Without the tests, there would have been less freedom to change the architecture to conform with new requirements.

The CI/CD pipeline runs on GitHub’s Windows 2019 servers.

It consists of running linter, unit tests, building the pyinstaller and the Windows executable app.

It builds pyinstaller natively, to lower the probability of TotalVirus Scanning marking it as false-positive virus. A requirement from NexusMod commitment to testing each file uploaded against viruses.
