About Me
Hi, my name’s Evan and I’m a software engineer. I am Malaysian and am currently situated in the UK.
Aside from spending my days writing code and tinkering with interesting pieces of software, I also enjoy searching for good food to eat and lifting semi-heavy weights.
I have mostly worked on backend systems throughout my career but am capable working in a full stack capacity.
