ChapHealth: Medical Discount Marketplace Startup

I was the lead Joomla CMS and platform consultant for this budding startup venture, providing advice and guidance on system architecture and coding practices. I was responsible for the ACL system design in relation to the project data objects and actors, and I provided UML for architectural elements and spearheaded the building of a specialized library build for a system to start to maximize code re-use.

Responsibilities ranged from performance to functionality, look, and feel.

Improved content loading times by 65%, through resource compilation, lazy loading, and restructuring advertising unit delivery. Facilitated the interface and wrote the API for access of content to for a social mobile application.

Built a complete photo management application for scrolling, commenting, and "liking" photos. Also built out new profile pages and content representation that aggregated data and social relationships.

JRumblr: Facebook for Joomla - Authentication, Registration, XFBML rendering and wall posting

JFacebook for Joomla represents a good deal of my open source project involvement. The application gives other Joomla developers and site administrators the ability to load the Facebook PHP and JavaScript SDKs, a PHP and JavaScript application structure that they may use to deploy their own applications, Facebook registration, configuration of the website's OpenGraph representation for accurate interaction with the Graph API, and loading of xFBML through the JFacebook HTML classes.

The JFacebook for Joomla application has been purchased over one thousand (1000) times. I've helped and provided support to over 500 websites using this package.

Astronomers Without Borders

I've been providing application development and general web presence services to AWB since Oct 2011. Some of the highlights of my work include custom application development using Zoo Framework, a complete redeployment of a site into Joomla 2.5, selection and integration of a subscription management extension, and consulting support for various implementations.

Ellesmere X-Ray Associates: External E-presence and Intranet
I did full external and intranet site deployments in Joomla 1.5. I custom built a file navigation extension using mooTree and deployed a highly functional gallery component for the intranet site and selected and populated the appropriate content construction kit for their needs on the external site. I customized their Gantry framework template to their exact specifications and implemented their Google Maps/Location finder.

Naturus: Subscription Service for Futures Traders

I brought the Naturus web presence from a grouping of static webpages and disjointed dynamic pieces to a consistent codebase under the Joomla! umbrella. I did a full site deployment, selected and customized the subscription application, and wrote a number of custom integration pieces, notably InfusionSoft API and the BeanStream Payment Processing API with specific Joomla! membership objects. I also configured the original learning management system for the service.

Inspiration Cosmetics

I came in to pick up the pieces of this project and deliver a working platform for the client's business goals. My responsibilities included:

- Managing the transition from the last environment and the last development team
- Managing and prioritizing launch-related tasks
- General troubleshooting and bug fixing
- Planning for future growth and scaling
- Mobile camera application workup for iOS


I was the technical lead for this startup.

This application is to help users from all sectors to collectively come up with ideas, group those ideas into options, and finally collectively assess those ideas through an exercise called paired comparison.

It's a full SaaS implementation where users have their own dashboard to hold their issues, questions, and the engagements that they run with their audience. There are a number of graphical and logic tools to help assess the results, and help guide the user through the process.

Its technology stack is LAMP, with Joomla! 3.x and Koowa Rapid Application Framework.

Formtools - Custom Form Building Package

This custom client project allowed them to move their guided exercises and checklists from downloadable PDF forms to a web-based interface complete with admin management and a flexible customer user experience. We had several design discussions and broke out the major domain entity objects: Projects, Tools, Exercises, and Answers.

The component also needed to provide scoring based on exercise completion, answers given, and percentage completion.

There also needed to be customizable feedback for each multiple-choice question.

This PHP application makes heavy use of the Formbuilder.js library to let the administrator build out the Tools (forms) by dragging and dropping the form elements into place.
