    EDUCATION, SKILLS, and EXPERIENCE I have a Bachelor's Degree in Computer Science and 8 years experience working on varied projects in a LAMP (Linux, Apache, MySQL, PHP/Python/Perl) environment. I also have a fair amount of experience coding in Java. In my college days most of my classes were taught in Java and I've had some opportunities over the years to use it both professionally and for personal projects. I'm fairly well versed in using the Swing graphical library (see the Stome project in my Portfolio below) for making GUI apps which work on Windows, Mac, or Linux. I'm also capable of writing multi-threaded code for responsive GUIs and fast performance where number crunching and analyzing large sets of data is needed. I am proficient at automating routine and repetitive tasks such as web crawling / scraping. I have written quite a number of crawlers in Perl in the past using the WWW::Mechanize library. Now I prefer to use Python for scraping tasks. Because Javascript use for generating dynamic content has become so common, simple HTTP client libraries (urllib2, curl, etc.) are becoming less relevant. Currently I use Selenium's WebDriver and the PhantomJS headless browser to navigate and fetch webpages and then I use lxml (the fastest DOM parsing library around) to parse the content. I'm also quite skilled at using regular expression pattern matching and extraction when needed. "The critical thing about the design process is to identify your scarcest resource." (Fred Brooks, "The Design of Design") DESIGN and COMMUNICATION Since I often write programs for myself, I am in the habit of designing things in a way that I would want to use them. However, I do encourage user feedback, because I've found others often see things in a different way than I do. It is the user who will ultimately be using the product, so it needs to be tailored to their personal tastes more than my own. Communication is key. I do my best to make sure I understand clients needs and also seek clients who are good communicators because I've found those relationships tend to work best. In application development, whether it be native or web-based, I concern myself primarily with the user's experience and so I do everything I can to make things work quickly and as expected. I'm a minimalist, so I make simple, user friendly interfaces. In web development, I use AJAX/JQuery when possible to provide a dynamic web experience. To me, everything is about the user interface. It's got to be intuitive and responsive. I work hard to meet this objective. "You have to work hard to get your thinking clean to make it simple. But it’s worth it in the end because once you get there, you can move mountains." (Steve Jobs) "When the solution is simple, God is answering." (Albert Einstein)  less

I am positive, proactive and motivated enough to set a goal with the intention to fulfill it. For the last 3 years I have been developing web apps related to CRM/ERP or any other administrative/organizational purpose on PHP/HTML/JavaScript, however, I would love to be involved in a video game development.

I do not feel as if I was bound to a specific technology, any professional should deliver a great job no matter what technologies are used. Describing me in few words, I am honest, thoughtful and persistent. I try to be kind whenever I can, I always say the truth, even in situations that could affect me, I take promises very seriously, so, I don't promise that easy, it would be unfair to say that I am a perfect person, like any human I make mistakes, and, when it happens, I recognize them, I apologize and I try to learn from them, I usually don't react violently and I have no criminal record.
