Daniel Garcia

I'm a fullstack engineer who cares about getting the details right and has a good time doing it. Six years in, mostly TypeScript and Node, building everything from APIs, services and the data underneath them to the React, Next.js and Angular front ends on top. I like code that still makes sense a year later, owning a system end to end, and teams where people joke around between deploys. Hand me a domain I've never seen and I'll be delighted — picking up new things is half the fun.
