Accomplishment: Commissioning of OCTYS VB2 Line 9 - August 2025 (awarded the OCTYS Trophy by RATP) CBTC system and integration testing: execution of test scenarios from a simulated PCC and a train HMI, in the OCTYS environment Use of testing tools: BAQUS and MobaXterm for executing automated scenarios and monitoring system behavior in real-time Simulated train driving: use of the onboard HMI to simulate driver actions (KCO/VT, alarm acknowledgments, manual/auto driving) Reading and interpreting technical specifications (PAS, PAE) to understand the expected behavior of the CBTC system Multi-level functional validation: interaction between PCC, SIG, onboard, HMI subsystems, and invariants Accompanying drivers onboard during functional tests to observe anomalies Coordinating with PCC teams and coordinating field tests

Ensure the safety of the SAET railway automatic system – New York Subway Verification and validation of configuration data (DCSYS) before their integration into the automation software database, using dedicated tools. Guaranteeing consistency between field data and database data, to ensure system integrity and compliance with safety requirements. Contribution to the reliability and safety of the communication-based train control (CBTC) system deployed on the New York subway lines. Exploitation of the invariant data construction specification from as-built data (DCSYS)

Carrying out various tests for the qualification of a prototype hybrid gearbox Conducting complex tests on test benches and vehicles to validate the performance and reliability of the prototype.
