10 years PHP experience, 30 years general programming experience in C, C++ and some variants of assembly language. I especially enjoy writing software to interface hardware, for instance getting a Raspberry Pi to communicate with anaesthesia monitors over RS232 or Ethernet, or health tracking watches to talk with desktop apps over Bluetooth or USB. Reverse engineering communication protocols is also fun.
I have experience with Qt for desktop and embedded GUIs and custom widgets.
Most of my PHP experience is on the backend of custom web software where much of the work is writing SQL queries, number crunching and complex algorithms. I can make functional, practical web pages using HTML5, CSS, and Javascript, but my artistic talents are limited.
