Fullstack Developer
Mariano Enzo Quiroga
Specialist in design and build high-performance web architectures, prioritizing scalability, maintainability, and sound technical decisions.
About me
I'm Mariano, a fullstack developer focused on solving complex problems at scale. I move comfortably across the stack, designing systems that grow without breaking. I work with the JavaScript/TypeScript ecosystem end-to-end — React, Next.js, Angular on the client; Node.js, NestJS, Express, and AdonisJS on the server. Based in Argentina, I collaborate with demanding remote teams.
