Client: Kontron Group
Position: Software developer engineer
Summary
Summary
Kontron Group is a company specializing in the field of railway telecommunications. They develop all the necessary technologies for GSM-R and FRMCS, both on the side of hardware and software. The BTS-R, the most represented element of the chain with more than 2000 units in France, is constantly being developed and new functionalities are regularly implemented. Each of them requires the completion of more than 80 tests, called "pre-integration sanity tests" to ensure their proper integration.
My objective was to develop an application that automates these tests, reducing the time required for their verification by over 80 hours and eliminate any risk of verification error.
