Hi!
My name is Jonny Arnold.
I am a software engineer. By day I even get paid for it.
I spend the majority of my time making cool stuff with computers, talking about software or playing computer games.
It’s safe to say I’m a geek. But hey, that’s cool now. Right?
Why Me?
I am passionate about software. Just ask my long-suffering wife. I am more than happy to sit (in a pub) and talk at length about the nuances of programming languages with you or discuss the latest technologies. I like training people and giving presentations because it means I’m not the expert any more; it gives me someone else that I can talk to about things I’m interested in.
I am a generalist. Hand me a problem and I will use the most appropriate tools to solve it, rather than bending my favourite tools to fit it. I’ve completed projects in several programming languages (Python, TypeScript, JavaScript, Ruby, C#) and dabbled in a few more (Lua, Rust, C++, Clojure, Scala) to make sure that when I get given a problem I know the best way to solve it.
I talk to people. I spend time getting to know you: primarily because I find it interesting to hear about your life, but also because it makes working with you a lot easier. Close relationships are valuable, especially when working in teams. People have called me friendly; I think I’m just interested in people.
It’s not just programming. I have skills in a wide range of fields, acquired in my spare time or during other projects.
