Jesús Leganés-combarro is a senior software architect with over 15 years of hands-on experience building and rescuing high-performance distributed systems, specializing in WebRTC, real-time streaming and AI-driven pipelines across Europe, the US, India and the UAE. He combines deep systems-level engineering (C++, Rust, Python, Node.js) with technical leadership experience as CTO/Deputy CTO, improving scalability, latency and maintainability where architectures have become fragile. Notable achievements include dramatic latency and memory reductions at scale (e.g., optimizing a media server handling 60k sources) and integrating codecs and low-bandwidth audio strategies for satellite and narrowband links. An active open-source contributor and WebRTC guru, he has contributed to well-known projects such as node-webrtc and mediasoup and worked on Wasmer and kurento utilities. Jesús also brings a strong teaching and mentoring background—689 hours of training across bootcamps, corporate programs and even robotics for children—helping teams adopt best practices, testing culture and measurable CI/CD improvements. Based in Abu Dhabi, he targets principal/staff architect roles where performance, reliability and interdisciplinary engineering rigor are mission-critical.
