Hi, I'm a Delphi developer with more than 30 years of experience (yes, since the times of Borland's Turbo Pascal). The past 20 years I was fulltime employed (in-situ) by two international organizations; the Inter-American Tropical Tuna Commission (San Diego, CA, USA) and the Food and Agriculture Organization of the United Nations (Victoria, Seychelles). I'm currently retired, and doing some freelancing work to stay busy and up-to-date.
I also have extensive experience designing and implementing SQL databases (more than 20 years), and developing database-centric applications (with Delphi and .NET).
I'm sure I can help wih your project, and re-design your POS in a way that would neet your new requirements.
If you think you may be interested in my services, please send me a message, so we can further discuss details of your project.
Best regards,
Marco García
