Gómez I build web platforms that hold up in production.
Over five years designing and deploying software for critical industries — from airlines to clinics. Microservices in NestJS, microfrontends in React, and pipelines that automate everything that can be automated.
01 — About me
Engineering with a focus on product and execution.
I'm an electronics engineer by training and a full-stack developer by vocation. Since 2020 I've worked on critical platforms where every millisecond counts and code must be built to last.
I'm comfortable moving between a React microfrontend, a NestJS service, and a GitLab pipeline. I enjoy solving scalability problems, optimizing asynchronous flows with RabbitMQ, and leaving architectures the next team can extend without fear.
When I'm not coding, I read, research, and keep learning — because the next useful tool is always one course away.
— built with coffee, curiosity, and automated tests.
