    Front to End Web Development with Human Touch

    United States - Last active: 11/24/2014

    My career goals is to serve your website needs. My view is that website development is three parts - design, development and management. I am willing to do all three of those things for you in a friendly and communicative manner. I taught myself how to program at the age of 13, and taught myself web development during college while working one of the three jobs I had at the time. All my jobs since college have been web development gigs. I do this work because I love it! My portfolio is a bit small because most of my gigs have been corporate business-to-business jobs and are signed away on NDAs. However, I assure you I am professional, top notch, and will do my best to get you the best website that you want.

    A energetic guy willing to help and make some money in the way.

    Brazil - Last active: 12/29/2014 - Tests: 2

    I'm thinking and playing with computers since I can remember. I’ve got my first computer when I was 12 years old. Luckily, this wasn’t a good computer this fact drove me through the programming world, because I spent my of my time coding small solutions just to have fun. Since them, I knew that I wanted to be a programmer for life. I took my first programming class when I was 14, finished my first college-level course with 16. In my last year in high school, I found a job to work building PDV software in a local company, but I resigned because I was dreaming about university. I started a Computer Science major in 2010, which opened my way to work in many fun projects. I helped to plan and build an online platform to connect hundreds of students and professors in order to help them to get founding for their projects. I also worked with investments, mobile apps, and many other small web applications. Until 2012 when I earned a scholarship to study abroad. In December 2012, I landed in Canada and had amazing 16 months, which I could study Computer Science at the University of Calgary, work as a summer student building new solutions for an Oil and Gas company, and I also had a blast connecting with people. I can tell from my past experiences that my greatest skill nowadays is to adapt and learn from new environments in order to solve any kind of problems. If you have a problem and you need help we can have a talk, I would love to help.

    Bioinformatician

    United States - Last active: 4 months ago - Tests: 6

    PhD-level Bioinformatician, with more than 7 years of experience analyzing human and non-human biological datasets. The types of datasets I previously worked with include Next Generation Sequencing (e.g. RNA-Seq, ChIP-Seq), cDNA microarrays, MS3 Proteomics, and Genome-Wide Association Studies. In addition to data analysis work (R, python, or perl-based), I have been involved during the last 2 years on website development projects (Django, Ruby on Rails, Backbone, Twitter Bootstrap, AWS). I also frequently develop web scraping and visualization tools. One of my main goals on oDesk is to enhance my knowledge and contribute to interesting projects, which do not necessarily have to be biology-oriented.
