How We Build

A small team with AI agents doing the heavy lifting

We build with Claude Code as part of the team. Agents write and review code, run tests, and research data sources, while we decide what to build and check every change before it ships. That is how a small studio runs several products at once.

Plan

Spec with AI

Every feature starts as a written spec and plan, drafted with Claude and reviewed by us before any code exists.

Build

Agents write the code

Claude Code works across the codebase: Expo screens, Supabase migrations, edge functions and tests, in parallel when the work allows.

Check

Humans and agents review

Agent code review, type checks and test suites run on every change. A person approves what ships.

Share

We open-source our tooling

The Claude Code skills we write for our own work become public plugins for researchers and teachers.

One codebase per product

Every app ships to iOS, Android and the web from a single Expo and TypeScript codebase.

Lean backend

Supabase, Postgres and edge functions. No API keys in the client, cached reads, row-level security.

Built for local users

Bahasa Indonesia first, local leagues and cities, and apps that work on slow networks and respect privacy.

Open Source & Research

We publish what we learn

Claude Code plugins we use ourselves, and the research behind our products.
