I rock and roll with a lot of tech.
I have my general "standard" set of tools, but in the past I've been no stranger to working with things that I wasn't quite sure about.
I try to stick with what I know. Generally, web work will be PHP, Laravel, mySQL/MirandaDB. Sometimes I'll add a splash of NodeJS in there and depending on the project, I'm no stranger to queuing, and caching subsystems, mailers, consuming APIs for breakfast, and rendering A+ scores on web speed tests.
For mobile apps, I like to roll with the native languages. On Android I use Java or Kotlin, on iOS I use Swift or Objective-C. When it comes to Games, I'll go cross platform with Unity and C#.
If you think you've got a project and would like to talk, send me an email.
