About Tony O’Brien

I started Sourcecode in 1991 to challenge myself as a developer and business man. I wanted the freedom to follow my passion where ever it might lead. There was never any thought to expand or take on other employees. Since 1991 I have  been involved in a variety of projects with many companies offering expertise in areas including: 

* All manner of ServiceNow design, development, customization, and administration. 

* VB/C#.Net, ASPx.Net, C/C++, linux and QT, Java and Javascript.

Database design and programmatic interfaces for Microsoft SQL, MySQL, Microsoft Access and others as well as deep experience with the accompanying database utilities such as Enterprise Manager and WorkBench.

Real-time Windows multi-threaded services for communications and database interactions.

* Graphical User Interface (GUI) design and implementation using WinForms, WPF and other frameworks.

Design, planning, implementation, and maintenance (SDLC) of custom applications integrating elements such as database, GUI, communications and report generation. 

Design and implementation of ASPx.Net ‘web portals.’

All Windows work has been accomplished within the Visual Studio IDE and associated source code vaults and Installers (i.e. MSI.) 

Netbeans based Android smart phone and tablet applications.

Particular expertise in designing and developing iris-recognition applications.

Other areas of expertise include implementing infrastructure software to automate manual processes and “real-time,” embedded (microprocessor, micro-controller) software development.
