I love engaging into the latest tech and trends as I learn about them through reading ThoughtWork's Technology Radar, checking out developer reports from different tech sites, and by talking to different engineers I meet on meetup events (Hooray for!). Recently, I've been exploring tools such as Puppet and Terraform, and I'm playing around with the amazing products Amazon Web Services (AWS) offers. They can't seem to run out of new interesting features and products for me to play with :)

I've also fallen in love with Python for the longest time now, which leads me to focus most of my free time this year in mastering the language. I owe Python big time for saving me minutes off my life, as I use it to automate life's boring stuff.

Apart from programming, I spend my leisure time picking my brain for logic and creativity by studying Chess. If I'm not playing on the board, you'll probably see me hanging out in Medium or asking tons of questions in Quora.

My end goals are to travel the world to meet all kinds of awesome people, teach the youth, and to improve the education system in the Philippines.
