My place in the company
As Head of Telephony Engineering, I architected and implemented a full SIP carrier infrastructure from the ground up, building it with failover redundancy, round-robin load balancing and Least-Cost Routing (LCR). A significant portion of my role involves managing carrier relationships and ensuring interoperability between our platform and upstream providers.
Launched RocketCell, a UK Mobile Virtual Network Operator (MVNO) backed by EE’s network infrastructure, providing mobile connectivity that integrates directly with the RocketPhone platform.
I developed a fully cloud-scalable PBX solution built on modern cloud-native architecture spanning GCP and Hetzner Cloud. This platform is designed for horizontal scaling to meet customer demand as the business grows.
