My passion is software development. It became my profession and my way of living. In the last two decades I have been developing several products for macOS and MS Windows like MaxBulk Mailer, a bulk email software, iCash, a personal finance software, FTP Disk, a FTP client and all kind of related products like eMail Extractor, eMail Verifier, eMail Bounce Handler, Loan Calc and Web Dumper. All those applications are available for download here.
For web site development I use PHP and mySQL a lot. PHP allows you to execute code on a web server and mySQL to store information. I have created all kind of service pages for the Maxprog company web site, a PayPal IPN Handler and an advanced Mailing List Manager called MLM. MLM provides some very important features like remote list handling, subscription management and click-through tracking to MaxBulk Mailer.
Running a software company implies responding to thousands of support requests per email or thru online forums, writing documentation, manuals, tutorials and FAQs. All the system including the store front and all the services including the site itself has to be monitored permanently. Finally you have to do the paperwork, but this is another story. I do all that as well with the help of my wife and a great accounting advisor.
