I've built digital experiences for established organisations, startups, and everything in between. The focus stays the same: systems that scale, solving the communication problems that actually matter, and keeping performance first throughout the entire process.

// About

Shipping a feature is easy. Keeping it fast for 500,000 users isn't.

Clean architecture. Real performance. No shortcuts that come back later.

I engineer digital experiences that work for the people using them and the teams maintaining them. Start with what users actually need, map flows, test early, build interfaces that don't need manuals.

The work spans Frontend Architecture, API Integration, and Fullstack development. Clean code for real conditions. Messy ones. If users get lost or the client can't update content without breaking something, that's a problem.

That mindset carried through real-time trading systems at Bittrex, a SuperApp serving 500K+ users at Farmacias Guadalajara, and a shared architecture that cut duplicate work by 90% across three product lines at Sissa Digital. Same principle every time: the interface is the easy part — the system behind it is where the real engineering happens.

Performance at Scale

500K+ active users, a 45% lift in mobile conversion, consistent 60fps — performance work that shows up in the metrics, not just the Lighthouse score.

Systems, Not Screens

A shared architecture reused across 3+ product lines, engineering standards rolled out team-wide, onboarding that doesn't depend on tribal knowledge.

Real-Time & Resilient

A custom WebSocket lifecycle abstraction powering live order books and price feeds — data ingestion decoupled from render, animations offloaded to the native driver.

What I Don't Do

  • —I don't ship a UI without understanding the data behind it.
  • —I don't add abstraction the team doesn't need yet.
  • —I don't call something done until it holds up on a slow connection.
