Hi there, nice to meet you, I'm Guedes
My name is João Guedes, I'm a backend engineer with a background in security currently working at Uphold. Welcome to my corner of the web, this is the portal to everything Guedes. It's where I keep my work, the snippets I don't want to google twice and the odd ramblings about whatever project or adventure I've dragged myself into lately. Stay as long as you want!
