I'm Santiago, a full-stack developer from Colombia focused on e-commerce systems — the kind of software where a broken checkout costs a client real money, so it gets built carefully. I handle the whole stack: database design, API architecture, payment integrations and the interface people actually click through.

I keep business logic separated from framework code — services live as independent modules, so testing and maintaining a project doesn't mean untangling it first.

Outside of client work, I follow football closely and spend time in video games — two things that, unsurprisingly, taught me a lot about handling pressure and iterating fast.
