Pepe Ruiz - Profile picture

Who am I?

I am Pepe Ruiz, a Full Stack developer focused on AI and intelligent solutions. My path into technology is not traditional: I began in Audiovisual Communication and Branded Content, where I learned to shape compelling narratives and approach problems from a creative angle.

Those storytelling and creative thinking skills now inform how I build digital solutions. I design scalable web applications that combine Computer Vision, Retrieval-Augmented Generation (RAG) systems for content generation, and Deep Learning models, using technologies such as React, FastAPI, PyTorch and LangChain.

My approach

Years working directly with people taught me the value of listening, understanding real needs, and solving problems with empathy. These human-centered skills complement my technical expertise and help me build software that truly connects with its users.

I thrive in agile teams and collaborative environments where I can combine technical craft with deep user understanding.

What I do

I have delivered AI projects with measurable outcomes: Computer Vision systems achieving 98% accuracy for automatic video detection, sentiment analysis engines with an F1-macro of 95.8% for toxicity detection, and enterprise content generation platforms built with RAG and multiple LLMs.

I am motivated by creating digital experiences that pair state-of-the-art technology with user-centered design to solve real problems in an intuitive and effective way.
