Harold Thétiot is a seasoned technology leader and CTO with 17 years of experience building scalable real-time and web systems, currently leading Sylaps to deliver secure WebRTC-based video conferencing solutions. His hands-on background spans full-stack JavaScript, Node.js, WebRTC, CDNs and high-scale infrastructure—Redis, Cassandra, PostgreSQL—and includes machine learning tooling like TensorFlow and CUDA for media processing. He has driven engineering at Netflix, Netvibes and Kaazing, contributing to massively distributed CDNs and front-end frameworks such as MontageJS and networked-aframe (adding WebRTC video streaming). An operator who still codes, he combines DevOps, reverse engineering and security expertise (pen-testing, encryption, TURN/STUN/SDP) with product leadership and a track record of shipping offline-capable and service-worker-enhanced web apps. Based in Pays de la Loire, France, Harold mixes entrepreneurial grit (founder/CEO roles) with deep systems craftsmanship across media, streaming and real-time communications.
