CHNAI LAB is the student product studio I founded in Phnom Penh. Seven product tracks, a live client storefront, and the systems that keep them honest — each labelled by what it can prove today.

About my work

Real products for the market I am from.

I'm Ka Vatana. I founded CHNAI LAB, a Cambodia-first student product studio in Phnom Penh, and I am a Year 1 Software Engineering student. I own the studio and build most of what comes out of it.

I want the public version of my identity to stay honest: I am not presenting myself as a senior developer. I am a student builder learning seriously through real projects, real community experience, and steady practice.

Work with me
  • Principle 01

    Evidence before status

    Live, local, simulated, and planned work are named as such. A demo is not a launch.

  • Principle 02

    People stay accountable

    A person owns product judgment, verification, review, and the decision to ship.

  • Principle 03

    AI stays bounded

    Agents get scoped context, never secrets, and everything they produce stays reviewable.

Current focus

What I'm focused on now

A snapshot of the work, studies, and responsibilities receiving my attention right now, beside the live map of everything I run.

“Ship working systems, document the tradeoffs, protect user trust, build with AI agents.”

What I can help with

Real builds, at the size I can finish.

I am a student, so I say what I can carry: bounded web builds, product validation, AI-native workflows, and student-team projects through CHNAI LAB.

Discuss a project
01

Web builds

Responsive sites and web apps in Nuxt or Next.js, with real verification, accessibility checks, and honest status pages.

Discuss this
02

Product validation

Interviews, the smallest useful slice, and a clear line between what is live, local, simulated, and planned. Cambodia-first.

Discuss this
03

AI-native workflows

Agents with scoped context and human approval for consequential actions, wired into real product work rather than demos.

Discuss this
04

Student-team projects

Bounded builds with CHNAI LAB: written scope, an accountable lead, and credit that holds up.
