About me
I have more than 5 years of experience developing custom web and mobile solutions, working with companies from the retail, betting, agriculture, and technology sectors. I’ve contributed to projects as an external consultant and in-house developer, improving performance, implementing scalable tools, and designing responsive user interfaces for clients and teams. My background includes hands-on experience with React, Next.js, Tailwind CSS, mobile development with Expo and React Native, and backend solutions with Node.js and GraphQL.
External Consultant
Currently
As an external consultant, I have contributed to several projects. Starting with my latest and current project, the AWS Community Day Mexico 2025 website in which I designed and developed the site until its deployment in production. In Bamagro, I designed and developed an administrator and a responsive client site, using PostGraphile for the backend and Vite with React for the frontend. At GetCannected, I participated in the development of a mobile app with React Native and Expo for patient management, although the project was assigned to another team. At Ennuma, I was in charge of refactoring the code and adding new features before the project came to an end.
