Up until 2019 we did both custom development and our own standard packages for the Windows PC environment - mostly using MS Visual FoxPro. (We still have about 30 user sites running our packaged software in VFP, which we continue to support.) From 2020 we have developed skills and capabilities in the Python ecosystem. This includes: - Integration with the major SQL engines: PostreSQL, MySQL, MS SQL Server, and SQLite - REST API applications - using FastAPI - SQLAlchemy and Django ORMs plus using SQL directly - Python based websites using Flask and Django on Waitress servers - AI processing of photos: vehicle type recognition plus reading licence plates - ONVIF camera applications, including motion detection and PTZ - Applications for the Raspberry Pi environment including GPIO outputs
