Who I Am

I'm Miguel Ángel Nieto

Miguel Ángel Nieto

Love your data!

Hello There!

Welcome and thanks for visiting! Let's introduce myself.

I've got more than 15 years of experience in different IT positions. I've been System Administrator, Technical Account Manager, DBA, Consultant, Support Manager, Support Engineer and Technical Trainer providing services for very different kind of customers. For example banks, governments, startups, social networks, retailers, television channels, videogame companies and so on.

During these years I've had the opportunity to work in many projects of different sizes, using a large range of services and technologies. But one day I decided to concentrate all my efforts in one single field: databases.

Thanks to that decision now I work as Technical Services Engineer in the Core Team of MongoDB. My plan worked! Databases are my main field nowadays.

I live in Dublin (Ireland). I moved here pursuing new career opportunities and challenges after 6 years working remotely for Percona. Everybody warned me about the weather but it is not that bad!

Enough talking about work! What I do in my free time? When I get some vacation days I buy a flight ticket to some far away country to dive in the ocean. Following sharks, manta rays and whales around the world is my way to escape from the day to day routine. Electronic music festivals (I'm looking at you Tomorrowland), Trance music, Videogames, American TV Series and Sports are other ways I have to spend time. If I can mix them with beer, even better.

Have a nice day.
