My company, API Skeletons, works through Upwork where I build custom applications for my clients.
I have worked in PHP and MySQL since 1999. Before moving to the web I worked in PowerBuilder using Oracle, SQL Anywhere, Sybase, and MSSQL. I have been programming since I was a teenager on a Commodore 128.
I am an expert at API architecture. Most recently I have moved to GraphQL exclusively. In REST I built APIs to Richardson Maturity Model level 3 , HATEOAS , with Hypertext Application Language as the JSON dialect.
