I offer freelance contract web development. My experience in brief:
PHP / MySQL - since 2005
HTML / JavaScript - since 2002
UI / UX / OOP - since 1995
I have been a contractor for a number of companies, including 2 years for Qualcomm (2015-7).
I have taken training courses in Laravel and WordPress (2018), though my commercial experience is in vanilla PHP.
I have integrated with numerous PSPs (payment service providers), and implements APIs, and code to utilize them.
I have also used Java in recent years for a science project of my own.
i do backend and functional frontend work; my skills are more on the functional / back end aspects.
Drawing on my long experience in this industry, I have a sense of what makes for good UX.
