JOSH ALPERTSOFTWARE ENGINEERFRONTEND & APPLIED AI

Building fast, reliable products that people enjoy using.

I'm a frontend engineer in Los Angeles. I led frontend work on FOX.com and TheUSFL.com, co-invented a patented AI game engine, and care a lot about the small details that make an interface feel right.

How I build

Three habits that show up in everything I ship, including this site.

Fast by default

Performance is a feature. At FOX, I led an optimization effort that raised Lighthouse performance scores by 75%.

Measured, not guessed

Good UX decisions come from evidence. At FOX I worked on setting up A/B tests on Optimizely so changes could be tested before the team committed to them, and I carry that habit into everything I build.

Accessible to everyone

Semantic HTML, full keyboard paths, and real contrast. Every animation on this site turns off when your device asks for reduced motion.

U.S. PATENT · GRANTED JUNE 2025

Just-in-Time Game Engine for Game World Development and Gameplay

Instead of shipping a pre-built world, the engine creates it as you play. AI models generate places, characters, and events in real time, while a structured knowledge store keeps each player's world consistent between sessions.
