    Spain - Last active: 1 day ago - Tests: 7 - Portfolio: 3

    I'm an expert in GNU/Linux systems and other UNIX flavors. I have experience in CDN deployment, Cloud Computing, High Availability, Monitoring and Video Transcoding and Streaming. I've been working with GNU/Linux since I was 14, what makes more than 10 years of experience so I have a good background in its evolution, tools and administration. I also use to implement tools in shell script and python and I use to code my applications in python. In the last 6 years I've been working as systems administrator and Integrator for an IPTV company that offers streaming and web services. I directed projects regarding software distribution and upgrades automatization, product deployment architecture design and products monitorization. I co-designed and co-deployed the cloud computing platform for the company, its CDN with High Availability, its telephony system and other projects. I really like to learn new technologies, test its capabilities and see what can they do. I like to meet new people, work with them and share knowledge and opinions.
