This page draws its light in real time with WebGL 2, which this browser doesn’t offer. The work, as plain text:

Hanil Metal — company website · 617 sentences carried over, 0 missing
Digital catalog for an industrial power-components maker · one dataset, three outputs: kiosk, web and USB
GOLD BASE · prices computed from the live gold rate the moment you look
Medimajor · Bridge Kothai · 110 passing bid-RPC checks under concurrency
Escrow marketplace app for trading cards · 119 Deno tests gating every commit
mai-eventic · people design the layout; the AI only fills in the materials
Conatus · no admission odds shown without evidence
Exhibition booth event · 961 real participants, 0 SMS errors

Everything starts as one beam of light.

30 web and app projects, built end to end for real clients and my own ventures. AI agents write the drafts — I own the judgment and the verification.

Tap to send a photon

02 — Refraction

Light shows its colors only when it bends.

One beam goes in. Five kinds of work come out.

Prism angle

Swipe sideways to turn the prism

03 — Spectrum

Where it lands, decisions crystallize.

One crystal for every project — thirty in all. Nine are opened here.

05 — Method

Set the angle. Send the light. Measure where it lands.

JUDGE

Judge

I own the decisions: scope, data model, security boundaries, and what “done” means.

DELEGATE

Delegate

AI coding agents (Claude Code) write and deploy the code to my specs; parallel agents run research and audits.

VERIFY

Verify

Nothing ships on an agent’s word. Every check below is first made to fail on purpose, so a pass means something.

Checks that travel from project to project

01Automated verification harnesses
02A negative control for every new assertion
03RLS proven to refuse with anonymous rights
04Real submissions on the live site, not just local passes
05Bundle hashes and strings compared after deploy
06Hooks that block DROP, DELETE and force-push

06 — Recombine

Back to a single beam.
