    As a full-stack developer with transferable skills and close attention to details, I am able to handle projects from start to finish with minimal supervision because I have an excellent general sense of what a product should and shouldn't do. I’ve designed and implemented many software systems. In most of the positions I’ve held, I’ve been involved in the full life-cycle of the project, from requirement analysis, initial design and implementation through to deployment and production support. My strongest technical expertise currently lies with Python (Django, Flask), PHP (Zend Framework, Laravel, Yii, FuelPHP, CodeIgniter), JavaScript (jQuery, AngularJS, Ember.js, Node.js), mobile apps (PhoneGap/Cordova and Corona SDK) and responsive web design with HTML5 and CSS3. I have also worked with a range of other languages and technology stacks, including Ruby, Perl, Shell scripting, Java, C#, Go, Lua and more.  less
