Rockstar🎓
Top SchoolDragos Vingarzan is a founder and hands-on software engineer with 11+ years building mobile core networks and a track record of shipping production-grade IMS, EPC and 5GC systems from research prototypes to commercial products. He founded Neat Path Networks after leadership roles at Twilio and UNIBERG and earlier built OpenEPC/OpenIMSCore as a Fraunhofer research lead, blending deep protocol-level expertise (SIP, Diameter, IMS, VoLTE/VoNR) with product-building instincts. As a contributor to the widely used Kamailio SIP server he’s fixed IMS modules and improved P-CSCF handling, demonstrating attention to interoperable, open-source telecom stacks. Based in Berlin, he pairs a Dr.-Ing. in Telecommunications with entrepreneurial drive, uniquely comfortable architecting carrier-grade control planes while still digging into low-level debugging and module fixes.
