I'm based in Barcelona, although I'm happy working for anyone
located anywhere (as long as we can find a time to meet).
< / li >
< li >
My career has focused in Data teams and positions, playing roles
such as Data Lead, Data Engineer or Data Science Researcher. I've
also tinkered quite a bit with many areas and technologies outside
of data, but not in professional, production-grade settings.
< / li >
< li >
Having said that, I have a lot of weird interests that might mix
somehow, including:
< ul >
< li >
Austrian economics and its societal and political implications
< / li >
< li > Bitcoin< / li >
< li > P2P and privacy friendly applications< / li >
< li >
Self-hosting and lowering the cost of people using advanced IT
on a personal level
< / li >
< li > Riding motorcycles< / li >
< li > BBQ-ing< / li >
< li > Being annoyingly contrarian< / li >
< li > 3D printing maps< / li >
< li > Teaching< / li >
< li > Film photography< / li >
< li > Tinkering with bicycles< / li >
< li > Calisthenics< / li >
