My most recent work over the last 8 years has been focused on APIs and microservices written in Go lang. Over the years I have worked in a few languages and have had experience writing code in all the 'C' languages: C, C++, C# and Objective-C. I've worked with most of the major SQL engines: SQL Server, MySQL and Postgres. I've wouldn't say I was a full stack engineer but have had experience with HTML, Javascript and most recently the JS frameworks React and Vue. I don't mind the front-end but more comfortable with the back-end.
