My Ethos

- Simple, meaningful programs can help people.

- Noble programs deserve good results.

- Simple is the best.

- There is no time like the present.

My Story

Since I was young, I decided to try my hand at computer programming because I thought it would be a challenge and I was curious.

It was an itch, I guess. There was creativity in my bones and as it turns out, making things with programs was what I was made to do.

Until now, I’ve been completely devoted to satisfying my curiosity, sweating out the details, and appreciating program more and more.

I enjoy working on all types of projects, but the work that I get most excited about usually involves Unix/Linux projects, fixing broken systems, and making people happier than they were before.

While there is no shortage of ideas for what we can do with the web and new technology, I’m mostly interested in what we should do with it. I want to help people. I want to change the world a little bit. I want to do work that matters.

What I Do

I am a Unix/Linux/VoIP/SIP system programmer.

The disciplines I enjoy most on a project is a strategy, information architecture, and creative ways of innovation.

In other words, I like helping people solidify their ideas or needs, sketching out some helpful ideas, then delivering the best possible working program to them.

I like to contribute the code to the open source, and spending most of the spare time to the Asterisk(https://www.asterisk.org/).
