Brian Paul Salinas

Front end developer

Transforming ideas into pixel-perfect reality

Pushing the boundaries of web development with React, Three.js, and cutting-edge technologies. 5 years crafting immersive, performant applications for companies across Argentina and Mexico. When innovation meets execution, exceptional products emerge.

I'm Brian, a Frontend Developer who turns technical challenges into business opportunities.

Over 5 years, I've shipped high-impact products for Mercado Libre, Globant, and US startups—optimizing performance by 70% building scalable architectures, and leading teams to deliver pixel-perfect experiences.

I don't just write code; I build systems that scale, refactor legacy chaos into clean solutions, and create component libraries that accelerate entire teams.

From complex dashboards managing millions in assets to immersive 3D web experiences, I bring a rare combination: deep technical expertise in React, TypeScript, and modern architecture—plus the strategic thinking to choose the right tools and structure for long-term success. I help companies ship faster, perform better, and scale smarter.
