About

The short version

I'm Luis Enrique Ton Liang — most people call me Chijong. I'm a fourth-year Industrial Engineering student at Universidad del Valle de Guatemala, graduating in 2027.

I build AI-powered B2B products. Right now my main focus is Mozt, a WhatsApp-native automation product for clinics in LatAm, where I lead the technical and product side. Outside Mozt, I work on local AI infrastructure (Sunny), interdisciplinary research (the Guatemalan MONIAC), and tooling that compounds the value of the time I spend building.

The thing that actually ties my work together is the intersection of three layers: industrial engineering's mindset for systems and processes, AI as a substrate for new kinds of products, and the operator's instinct for shipping rather than over-planning.

Current focus

Mozt is the priority. Beyond that, I'm building publicly — this site, the blog, and the projects on it are part of the same bet that real work, shown openly, compounds faster than polished credentials.

How I work

Delegate code, own decisions

I delegate precise code to Claude Code. I spend my time on architecture, decisions, and verification — not boilerplate.

Shipped beats almost-shipped

One shipped thing beats ten almost-shipped things. Build-in-public is a forcing function for that.

Ideas survive concrete pressure

I take ideas seriously when they survive a real user, a real dataset, a real deadline. Until then they're hypotheses, not commitments.

Background

UVG, Industrial Engineering, class of 2027. Second place at the Winter Simulation Conference 2025 in Seattle with a multi-agent RL approach to container port logistics. Co-founder of Mozt. Based in Guatemala City.
