#### Summary
Since August 2024 until March 31, 2025, I worked as IT Architect at Strukton.
* Introduced architecture-driven work practices,
* starting with the development of an Enterprise IT architecture aligned with the business,
* to be integrated with domain and solution architectures based on business processes according to BPMN 2.0.
* This resulted in the delivery of an enterprise IT architecture document.
* In the area of domain architecture, contributions were made to application integration.
* In addition, activities were performed focused on
* application rationalization,
* initiating projects for software refactoring,
* and introducing innovative software technologies, including graph databases.
From early 2019 until May 31, 2024,
* I was involved via IDC-Metri as a program and domain architect at ProRail for the GSM-R Fit for Service program and its subprojects:
* core relocation,
* GRI,
* and VR-2.
* The results achieved include:
* re-tendering of the GSM-R management and maintenance solution;
* successful migration of the management and maintenance solution from Mobirail to Nokia and Cellnex for the GSM-R network;
* implementation of a new GRI solution (telephony) for Traffic Control;
* and relocation of the GSM-R core and GRI environment from KPN data centers to those of ProRail. The VR-2 project, focused on the replacement of telecom masts, is currently still ongoing. After completing the GSM-R Fit for Service program, I also served as solution architect for the ERTMS program from October 1, 2023, until May 31, 2024.
Since 2008, I worked as a consultant at IDC-Metri.
