At HPE, I own SIMULAP, a Java\-based protocol testing platform used to validate telecom infrastructure before it reaches production\. My work sits at two layers most engineers only touch one of: the protocol layer \(SIP, LTE, Diameter, TCAP, TLS over SCTP/TCP/UDP\) and the systems layer \(JVM internals, concurrency, thread management, performance\)\. The work I'm most proud of isn't a feature \-it's a production incident\. A live telecom platform was pinned at 302% CPU with a hanging JVM startup\. Using Java Mission Control and thread dumps, I traced it to lock contention: threads busy\-waiting on a shared monitor, burning cycles with zero useful work\. Removing the contention point brought CPU down to 0\.7%\. That's the kind of problem I like \- where the fix requires understanding both the protocol traffic and the runtime underneath it\. Concretely, I've: Built LTE and SIP protocol plugins with TLS support over TCP/SCTP, Added IPv6 support to a Diameter implementation used in production, Redesigned data structures and thread management to resolve critical performance issues under concurrent load, Owned releases end\-to\-end: RPM packaging, Docker images, documentation, CI/CD via Jenkins Before this, I worked on HPE's OpenCall Media Platform \(SIP, RTP, real\-time audio/video\), where I optimized RTP stream handling and built traffic\-generation tooling to simulate real call, DTMF, and media scenarios at scale\. I'm looking for roles where protocol\-level networking knowledge and systems\-level debugging both matter, telecom software, backend infrastructure, distributed systems, or platform engineering \- ideally in Europe, Singapore, or Australia\. Open to relocation, visa sponsorship, remote, or hybrid\. Outside of telecom infra, I build systems projects for the practice: a Go\-based multi\-tenant AI security research prototype, and a multi\-agent reinforcement learning system for race strategy\.
