At CJ Dev, I developed responsive portfolio architectures and web applications focused on modern web and accessibility standards. I implemented interfaces and interactive components using React, JavaScript, HTML5, and CSS3.

As an AI Quality Analyst at T-Maxx, I evaluated Large Language Model responses for accuracy, formatting, and logical reasoning. I also audited structured outputs such as JSON for compliance with technical guidelines.

Through AI Training Platforms, I evaluated and transcribed audio recordings for AI training projects, checking recordings against reference scripts for audio quality and compliance.

I also evaluated AI-generated personal finance and investment content, applying knowledge I developed independently. I'm studying for a B.S. in Information Technology & Digital Innovation at Universidad Politécnica del Valle de México.
