    Consultant, Project Manager, Full-Stack Dev, Sysadmin and Designer

    Canada - Last active: 11/18/2014 - Tests: 3

    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.

    Mobile App Developer

    United States - Last active: 11/01/2012 - Tests: 1 - Portfolio: 2

    Looking to work on great cross-platform mobile projects, focusing on Appcelerator Titanium. Over the past 4 years, I have changed my focus from building clean, high-performance enterprise and consumer web applications to doing the same for consumer mobile Apps. I strongly believe in the Titanium platform, because of its ability to build cross-platform apps using honest-to-goodnes native UI for each platform. I am Titanium certified, a Titanium Titan, and work closely with Appcelerator in many aspects. I use, and have helped shape some of the best practices for the platform. I have good experience with building Native iOS applications, and have excellent experience with Java, and as such bring a fundamental understanding of how Titanium code actually runs and works on each platform. I am *not* a JavaScript developer trying my hand at mobile development. You will get apps that work and perform just like you expect. I do all of my own work, am a US citizen, and am available for independent consulting and training. I can also come in and clean up and convert existing, underperforming projects, and bring them up to the latest SDKs and best practices.

    I am an extremely skilled, motivated, and highly knowledgeable IT professional with 15+ years in the IT industry. I am also an EC Council Certified Ethical Hacker, and in addition to security services, I provide a vast array of technical solutions to both businesses and individuals. From network/server/workstation planning and implementation to advanced troubleshooting and traffic analysis, I am THE answer to your technical demands. Add to this the fact that technology isn't just my profession; it's my passion, and you will discover why my clients have been with me for years and wouldn't consider switching. I absorb and become well-versed at any issue thrown my way, and will get to the bottom of whatever roadblock I encounter. Who I am not: your average neighborhood tech geek, a rep from a fly-by-night shop, or someone sending proposals to any listing that appears. I choose my applications very carefully, and make sure I have budgeted enough time to complete the task required. I also do not apply for jobs that I'm not 100% certain I can handle. Due to these and many other reasons, I have built a solid name for myself locally, and will do so here as well. You'll be glad you chose to have done business with me, and I look forward to meeting your technological challenges head-on.
