What I'm looking for

I'm looking to build stable, scalable, well-structured web solutions for corporate or government environments, contributing across frontend, backend, authentication, integrations, automation, and deployments.

I've built and improved internal web applications for Tu Casa Express and Instituto Mexicano del Seguro Social (IMSS), working across React, Angular, Node.js, Express.js, and TypeScript. At Tu Casa Express, I integrated REST APIs, implemented MSAL/Azure AD automated login, and managed Azure Repos and IIS deployments.

At IMSS, I optimized internal applications, managed large data volumes using security best practices, deployed systems on OpenShift, and improved stability and response times through refactoring and automation. I also created technical documentation, user manuals, scripts, and operational support materials.

Earlier, I developed MVC-based internal systems and database structures using PHP, MySQL, MariaDB, and Spring Boot. I also supported WordPress sites, built responsive landing pages, and improved UI/UX for commercial digital campaigns.
