Building things with
the kind of care that
makes agents
feel inevitable.
Luis. Industrial engineer, CTO at Mozt. I build AI systems for Latin American operations and write about what works.
Notes from the workshop.
Essays on building, on building with AI, and on the practice of doing both from Guatemala.

Meet Claude (and the era it opens)
What Claude actually is, the three primitives every surface relies on (MCPs, Skills, Plugins), the four rooms it lives in (Chat, Code, Cowork, Design), and why the execution layer is collapsing into the model.

Systems thinking is the bottleneck skill
Execution is collapsing into the model. The skill that doesn't collapse: identifying the right bottleneck, predicting where it moves next, and designing the shape of work around it.

Agentic orchestration: the manager pattern that's reshaping B2B AI
The most useful shift in AI right now isn't a smarter model. It's structure. Multi-agent orchestration gives teams a way to coordinate several AIs the way a manager coordinates a small team. Here's the honest map: patterns that work, costs that bite, and where LATAM operators have room to move.

Selected work.
A selection of the projects, ideas, and systems I've been building as an engineer, creator, and founder. How I'm learning, experimenting, and turning concepts into real solutions with purpose.

Who is writing this.
I am Luis Enrique Ton Liang. Most people call me Chijong.
Industrial engineer, co-founder and CTO at Mozt, fourth year at Universidad del Valle de Guatemala. Born in Guatemala in 2004. Most of the doors I have walked through I credit to faith more than to my own planning. At Mozt we build AI systems for operations across Latin America. Vita, our first vertical, is an AI receptionist for medical clinics.
Industrial engineering's mindset for systems and processes, applied to AI as a substrate for new products. Operator's instinct over architect's: ship before you over-plan. One shipped thing beats ten almost-shipped ones. This site is the workshop where I write about that work.

Currently open to collaboration.
I read every message. Best for project conversations, research crossovers, and questions about what I publish here. Slow on cold pitches.
