My name is Leo Adhemar R. Tan and I live in the Philippines. If it’s not a sunny day here, then it’s raining. All year round. Regardless of the weather, I prefer to stay indoors and spend my time in front of a screen consuming content, engrossed in a project or learning something.

I am currently employed full time as a Systems Engineer working on complex software application systems for the Air Navigation and Air Traffic Management industry. This job allows me to travel to customer sites for installation and training in countries like Germany, Papua New Guinea, Myanmar and the United States.

Since I prefer to keep myself busy during my free time, I have engaged in a variety of Freelance online work revolving around the WordPress ecosystem. I enjoy this activity and I consider it my way to relax after working at my day job. Working in the Enterprise and in Freelancing allows me to enjoy the benefits of both worlds and I count myself very lucky and blessed that I am able to do this.
