Full-Stack Developer

Erik
Quesada

Building production SaaS applications with Next.js, React, and Python.

About Me

I'm a full-stack developer who builds SaaS products from the first line of code to full production. My time in technical support taught me how to spot real user frustrations and turn them into practical, scalable solutions.

My work centers on Next.js and React on the frontend, with Python and FastAPI driving the backend. I handle everything from Stripe payment integrations to real-time features with Convex to workflow automation that saves teams hours. I care about building systems that hold up when real users rely on them.

Right now I'm developing InvoiceHound, a full-stack invoicing platform for freelancers. I've also built enterprise email automation tools that cut setup time from roughly an hour to under two minutes. I write code that solves problems, ships quickly, and scales with growing products.
