About
Hello
I'm a computer engineer from Universidad de Chile, graduated with highest honors. I've spent the last few years building full-stack web applications end to end. I am most experienced at doing APIs in Express and FastAPI, interfaces in React and Vue, and the integrations that hold the two together. At Crazycake Technologies, I worked with clients directly from project planning through delivery.
My other passion is cybersecurity. I wrote my thesis on detecting hidden spy devices through packet sniffing. I've taught seven semesters as a teaching assistant, including a competitive hacking workshop, and built course material focused on cybersecurity.
