Bringing the platform into production
I took over delivery work on Swisscom’s next-generation virtual routing platform during its later development stage. I helped bring the remaining development work into production and have continued working on technical and operational improvements.
The platform uses vMSR to replace a legacy virtual routing environment. Getting it ready involved working with software and network engineers, infrastructure and operations teams, product colleagues and technology vendors. I worked through dependencies and technical escalations, supported migration planning and helped troubleshoot production issues.
Supporting customer migrations
The migration programme spanned more than 1,500 enterprise customers. Before a cutover, the network, platform and orchestration systems all had to be ready, with operational support available if something went wrong.
I supported planning and cutovers, investigated problems across those systems and fed findings back into platform improvements. With many migrations running in parallel, we also had to account for capacity and the dependencies between migration steps.
Improving the migration tool
Alongside the routing platform, I worked on a tool used to carry out customer migrations. I simplified deployment and setup, maintained its production code and environments, and improved the engineering workflows around it.
These improvements contributed to an approximately 40% cost reduction.
Testing shorter interruptions
I contributed to validated live-migration testing that reduced customer disruption from approximately 4–5 minutes to 10–15 seconds under the tested configuration.
