Rockstar🎓
Top SchoolRalph Meijer is an experienced software engineer and owner with over 18 years building distributed, real-time and federated communication systems, currently serving as VP of Technology at Netdata and Chair of the XMPP Standards Foundation. He combines deep protocol and backend expertise (XMPP, WebRTC, real-time signalling) with hands-on systems work across companies from startups to Elastic and VEON, driving architecture, security, and operational reliability. Known for bridging technical and non-technical stakeholders, he translates product, legal, and design requirements into pragmatic engineering trade-offs that balance privacy, performance, and maintainability. Ralph is an active open-source contributor—having contributed to high-profile projects like Logstash and Twisted—and has practical experience hardening cloud proxies, TLS migrations, and large-scale logging and metrics pipelines. He mentors small engineering teams, leads federation and migration efforts, and retains a curiosity for low-level protocol details born from years chairing standards work. Based in Veldhoven, Netherlands, he pairs formal CS training with a long track record of shipping resilient, privacy-conscious communication platforms.
