I'm mainly a curious person, so anything goes.
I'm an expert at cloud server managing, specially with AWS and GCP.
I have worked with servers running linux and windows.
I know a lot about SQL and NoSQL databases.
I'm an expert with MYSQL and ElasticSearch, but also have worked with many others.
I also have a lot experience using PHP, and also C++ and Java.
It's not my wrongest skill, but I can handle myself using HTML5, CSS and JS.
