Guilaume B.

I'm a passionate developer with more than 7y of experience in the JS ecosystem. I've built complex system with NodeJS and React for multiple startups. Always looking for a better way to code things, I closely monitor technological developments on HN and other sources to find the right tool for the right project.
I've also built two SaaS products and I try to see the big picture of every project. I do not stop at the code but always focus on the product to make the best decisions.

Some of my areas of expertise:

• Live and On Demand web video (HLS, Dash, RTMP, MSE)
• Realtime web system (WebSocket, WebRTC)
• Backend scaling (worked on products with 300k+ simultaneous users)
• Cloud cost optimisation (AWS, Google Cloud)
• React, NodeJS, Redis, PostgreSQL
