    Full-Stack JavaScript, NodeJS, Zend Certified PHP + More

    New Zealand - Last active: 17 hours ago - Tests: 4

    I am a Senior Software Engineer with over 8 years professional experience. I am from New Zealand currently living in Thailand, my time is flexible and I am happy to work hours to fit your needs, I'm easy going & take responsibility for my work. For the last 4-5 years I have been working in a small team as the Lead Developer on a large scale web application primarily written in JavsaScript with heavy usage of the Sencha ExtJS framework on the front-end, NodeJS on the back-end and Cassandra as the database. I keep up to date with latest technologies and consider myself a very quick study able to pick up another language or technology in a very short amount of time as needed. My key areas of expertise are: * Front-end JavaScript - Sencha ExtJS - Sencha Touch for native and web based mobile development * Back-end JavaScript with NodeJS * PHP - I am a Zend PHP Certified Engineer (http://www.zend.com/en/yellow-pages/ZEND012419) * MySQL, MongoDB and Cassandra databases - Special note of experience of expertise with Cassandra NoSQL database for scalability and high availability * General Linux Administration - I have been a full time linux user for my day to day computing since 2006 and have configured many web servers and other services on different linux distributions. * Cloud hosting - Experience with Rackspace Cloud & Amazon Web Services I also have experience with Bootstrap, Kockout, SilverStripe, Java, C#, HaXe, HTML/CSS, Git/Github and many more acronyms, libraries and frameworks. Work Policy: * All my work is version controlled meaning at anytime it can easily be returned to a previous state. * I try to deliver the best quality possible, but this is often a trade-off between time & budget. I will help find the best balance for the specific project situation. * I'll be honest, if I am out of my depth I will tell you or if I see how you can save time/money even if that means less billed hours for me I will make suggestions.

    Software Engineer

    United States - Last active: 07/31/2014 - Tests: 5

    Quick learner with an attention to detail, an eye for solving problems that cross organizational boundaries, and a high propensity for asking questions to understand the underlying goals. I excel when I am pushed to master new concepts, and I am not afraid to participate in project aspects that are outside of my nominal domain. I strive to maximize my contributions wherever possible. I am a software developer with experience in relational database management, Java HTTP server maintenance, JavaScript web application design, and automated CI testing. When necessary, I am capable at acquiring domain expertise and providing guidance for the organization. I am comfortable communicating specific knowledge to both broad and targeted audiences, and I am always looking for better ways to keep stakeholders up to date. Above all, I'm looking to help out and do new and interesting things. If you've got something in mind, let me know.
