Hi! My name's Kevin. I'm an autodidact software developer, speaker and blogger. I'm CTO with the talented team at Resource Guru where we build the best team scheduling tool on the web :). I've been working remotely full time since 2016. I live in Newcastle upon Tyne, UK, having previously worked as a Lead Ruby and JavaScript developer at Platform45 in Johannesburg, South Africa.

I primarily use neovim on macOS with a highly customized vim config. Vim lets me file frequently repeated actions behind mnemonic key mappings so I can focus more on code and less on the keyboard and mouse. My preferred hammers are TypeScript, Go and Ruby.

I've been writing software for as long as I can remember, first on my Dad's Commodore 64 before learning QBASIC on DOS, followed by Pascal, Delphi, C and PHP during primary and high school years. My professional career started off in the .NET stack, writing C# with .NET 3.5 and 4.0, as well as working on data intensive OLTP and OLAP systems using Microsoft tooling such as SQL Server and Analysis Services. I progressed into Ruby and JavaScript in 2011 with Ruby on Rails. Since then I've spent countless hours honing my skills on the journey to mastering the art of software development.

I believe a good craftsman should be willing to teach and mentor others. I regularly attend and speak at usergroup events and conferences. I was a regular panelist on the ZADevChat podcast from 2015-2017 with Kenneth Kalmer and Len Weincier.
