Gardener of Systems
Hello, I'm Zen.
For years, I struggled to describe what I do because every answer felt incomplete.
I'm a software developer, but that isn't the whole story.
I'm an entrepreneur, but that's only one expression of my work.
I've worked in agriculture, education, technology, construction, nonprofit initiatives, and community development. At first glance, they seem unrelated.
Projects in motion. Each lives at its own subdomain until it’s ready to graduate.
AI literacy for Filipino teachers and students at Leyte National High School and beyond. Bringing the next literacy gap into reach for the kids most likely to be on the wrong side of it.
A family foundation in formation, built to outlast any one of us and to direct support toward the next generation.
A small beach-farm homestay in Eastern Samar. A place to come for the scenery, stay for the wonder.
ZenOS is a cognitive operating system that enables humans and AI to collaborate through interdependence. It organizes work around explicit intent, evidence-backed knowledge, versioned workspaces, specialized agents, and transparent delegation.
A clean, calm one-bedroom stay in Parañaque for staycations, quick city errands, and overnight layovers before an early flight.
A boutique virtual assistant agency for coaches and therapists, organized around Bayanihan, Malasakit, and Pakikisama as operating values rather than slogans.
In Waray, balay means home, and mana means what is handed down - an inheritance. A home meant to be passed on. The name holds a belief we have come to live by: we do not own the earth. We hold it for a while, and we pass it on.
Construction and solar work, in partnership. Past projects, plus a calculator for residential solar costs in the Philippine context.
Ugnayan Systems builds the connective layer that lets a small or mid-sized organization's separate systems - records, inventory, messaging, scheduling, audit - work as one coordinated whole, operated by an AI assistant that staff actually talk to.
