Full-Stack Developer & Systems Architect

I build accessible, scalable digital experiences for the web, specializing in complex systems and AI integration.

Architecting Ideas into Reality

From complex systems to cutting-edge AI, I build digital solutions that solve real-world problems and drive innovation.

A Journey of Building, Learning, and Leading

My career began in December 2019 as a full-stack developer, where I quickly learned the ropes of Linux, DevOps, and backend architecture. My first significant challenge was at Muttech Solutions, where I was part of the team that developed "SEC" (Sistema Especializado en Cobranza). This project was a masterclass in complexity, requiring the integration of Calls Over IP, dynamic reporting, and synchronization with major bank systems.

This experience laid the groundwork for my next major project: "Justicia Laboral." I single-handedly built this platform from the ground up, designed to streamline legal operations in Mexico. As the sole technical architect, I later led a full migration of the system to a modern stack, leveraging Next.js and Supabase to achieve significant improvements in speed, security, and availability.

I then brought this expertise to Finexitus as a full-stack developer. My primary role was to design and build an ERP solution from scratch, managing complex operations for investment contracts and renewals. The biggest challenge here was creating a seamless synchronization system between the ERP, the public website, a document signing API, and customer emails.

Recently, I have expanded my skillset by earning a "Data Science & AI" certification from Tecnologico de Monterrey. I immediately put this knowledge into practice at Finexitus, implementing AI solutions to drive business value and keep the company at the technological edge.

My journey has taught me a simple but powerful truth: your value is directly correlated with the real-world problems you can solve. I am a lifelong learner and am always seeking the next interesting and challenging project where I can turn an idea into a reality.
