I’ve been working with WebRTC since 2012, less than one year after they were started the discussions about design and develop its specifications, being one of the pioneers of this technology in Spain.

I got involved on it while developing ShareIt!, the first serverless P2P filesharing application written fully in client side JavaScript, and with whom I won the “Most Innovative Project” award at the spanish national VII Free Software Universitary Championship. To develop it, I also needed to create DataChannel-polyfill, the first working implementation of WebRTC RTCDataChannel API, four months before it was available in experimental versions of both Chrome and Firefox browsers, using for it WebSocket connections instead of a SCTP connection as transport layer.

Thanks to both projects, I was invited to do a keynote in the first Spain WebRTC summit, hosted at Madrid Polytechnic University in November 2012, and got a paragraph talking about my work at HTML5 for Masterminds book, written by John D. Gauchat. After that, I was invited to work at eFace2Face, and later I joined the Kurento team for two years, where I was responsible for design and develop the Node.js, Javascript and HTML5 APIs for Kurento media server.

In the next years, I’ve been working as WebRTC Expert for multiple projects, including the two start-ups where I’ve also been working as CTO, UnifyMe and lingbe. But since short before it started the Covid-19 pandemic, I got contracted each time by more companies to work as freelance WebRTC Expert, so in December 2020, I decided to work full-time offering my services as WebRTC Architect and consultor, and as Mediasoup Expert, in addition to develop my own WebRTC and streaming projects.
