Here is a small smaple of work that I've done for different clients. If any of these sound like they may be applicable to your project, please feel free to inquire about details.
This website was built for the Field Kindley High School Class of 1993. Although it was done for very low cost, the site was tested on several browsers and utilized two persistent databases. The site quickly increased in popularity, and displaced a leading commercial class reunion website as the preferred forum for the event planning and distribution of contact information. The dynamic parts of the site were generated with Python, and used that language's built-in object serialization technology. Please check out the screenshot below for a closer look at the site.
This client hired Maxint Consulting to install and configure a number of Linux servers to replace problematic Windows-based systems in their Internet Service Provider business. They requested a new Linux installation, and the configuration of a DNS system and a mail server. I provided them with the latest Slackware Linux distribution, along with the Bind DNS server, and an upgrade to the latest version of the Sendmail email server. The Sendmail upgrade was done because they also requested mail server customizations that required Sendmail to be be re-compiled in order to activate additional features. The special additions consisted of a virus scanner and a specially written mail filter to limit the number of emails that individual users could send per day. My relationship with this client is ongoing, and will probably result in more projects in the future.
Prior to the formation of Maxint Consulting, this client, an oil refinery, hired me to produce a database and corresponding data entry application to store periodic gas chromatography information. They requested that the application be written in Visual Basic, since that was the language used for all of the plant's other custom projects. The application was intended to replace a set of Excel spreadsheets that were copied and edited from day to day in order to create tables of new values. Since it would be used by only one or two lab technicians, I used Microsoft Access for the database, in order to avoid unecessary issues with running a separate database server. The data entry application was written as a stand alone program using Visual Basic 6.0 and Data Access Objects, so the system could be easily scaled up to a real, ODBC-connected relational database in the future. Its additional features included statistical outlier detection to help signal typographical errors.
