Resume/C.V.

My work focuses around object-oriented application design and development for Mac, including Mac desktop, iPad and iPhone. Mac software design and development has become my passion. I have a keen attention to detail and a strong aesthetic sensibility. I guarantee the quality of my work and my clients' satisfaction.

My process to writing quality software is more than just hacking code. Good design is critical for an app to be successful and easy to maintain. This requires following well-established design principles: the same principles employed by Apple and other design-centric companies. Quality software must include careful attention to detail and the overall user experience, a solid architecture, coding best practices, and great artwork and graphics design.
Service Description
I'm a senior software engineer and UX designer with many years experience in software development on both commercial and open source projects (see http://sourceforge.org/projects/aztsearch for an example of one of my open source projects). I received Bachelors and Masters degrees in computer science, mathematics and business administration at the Universtiy of Calgary, Alberta, Canada.

I'm also interested in social applications of technology. Particularly open source technologies applied to transparency of government, participatory democracy, connecting people and ideas, collaboration, information access and representation, individual privacy, and more recently, Bitcoin. All within a Mac OS X, Cocoa, Objective-C, and iOS context.

Some of the technologies I've worked with over the years include Objective-C, Cocoa, AppleScript, Java, C++, C, Scheme, Android Platform, Perl, HTML, XML, JHTML, Qooxdoo JavaScript/Ajax Framework, PHP, Javadoc, Xcode, Eclipse, JUnit, Swing, SWT, CORBA, MySQL, SQLite, Oracle, JDBC, Git, GitHub, Bugzilla, Subversion, CVS, Apache Web Server, ATG Dynamo Web Server, Servlets, Unix, Shell Scripts, OS X Admin, OpenGL, OpenInventor, NeXTstep, OpenStep, Mathematica, and Agile/SCRUM development methods.

Generally, unique and interesting applications of technology with a distinct design-focus is often enough to pique my interest. Feel free to drop me a line to discuss your Mac/iPad/iPhone project requirements.

A text-to-speech translation system provided the user with the required aural information in the form of synthesized speech. Technologies included Objective-C, NeXTstep APIs, Interface Builder, Project Builder, NeXT platform, and graphics tablets.

Graduate supervisor for Master of Science degree. The topic of my M.Sc. research, "Feature-Based Face Detection," involved obtaining detailed information on the location, shape and structure of various landmark facial features such as the mouth, nose, eyes, and eyebrows without user intervention. A variety of computer vision techniques were employed, with several novel contributions to the discipline. In addition, a number of techniques for tracking lip movement were also examined. This work has a large number of practical applications, most notably in the areas of face recognition and human-computer interaction.
