About me

Frontend Architect & Engineer

Mathematician • Cosmology & Systems

Hey! I'm Marco Romero—a Frontend Architect with a background in Mathematics. I view software engineering through the lens of analytical structure, geometric abstraction, and system performance.

Currently, I lead frontend architecture at Grupo Salinas, where I design resilient micro-frontend ecosystems, enforce strict Core Web Vitals budgets, build automated verification harnesses, and mentor engineering teams.

Beyond The Code • Personal Passions

Cosmology & Science

Fascinated by astrophysics, general relativity, and non-Euclidean geometry. Mathematical thinking drives how I structure systems.

League of Legends • Vi Main

Avid Summoner's Rift competitor. Big fan of Vi—bringing high-impact, direct execution both in-game and in codebase architecture.

Music & Soundtracks

Heavy rotation of Latin Mafia on repeat during deep coding sessions and architecture design.

Systems & Applied Logic

Applying analytical problem-solving and structured logic to simplify complex frontend codebases and eliminate technical debt.

“Inherited Will, the Destiny of the Age, and the Dreams of its People... these are things that cannot be stopped. As long as people continue to seek the answer to freedom, these things will never cease to be!”

— A Motto for Continuous Growth & Adventure 🏴‍☠️
