WebRTC

I’ve been working with WebRTC since 2012, less than a year after discussions started around designing and developing its specifications, which made me one of the pioneers of this technology in Spain.

I got involved with it while developing ShareIt!, the first serverless P2P file-sharing application written entirely in client-side JavaScript, which 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, using WebSocket connections instead of a SCTP connection as the 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 my work was mentioned in the 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 designing and developing the Node.js, JavaScript, and HTML5 APIs for the Kurento media server.

In the following years, I worked as a WebRTC expert on multiple projects, including the two start-ups where I’ve also been working as CTO, UnifyMe and lingbe. But shortly before the COVID-19 pandemic started, more and more companies began to hire me as a freelance WebRTC expert, so in December 2020 I decided to work full-time offering my services as a WebRTC architect and consultant, and as a Mediasoup expert, while also developing my own WebRTC and streaming projects.
