I build experimental products at the intersection of AI, Web3, games, and developer tooling.
My work usually focuses on practical user-facing prototypes: miniapps, on-chain interaction flows, AI-assisted interfaces, local automation tools, and game systems that can be shipped, tested, and improved in public.
- Based in Indonesia
- Working mostly with TypeScript, React, Next.js, Solidity, Python, and local AI tooling
- Interested in Farcaster miniapps, Base, autonomous agents, MCP workflows, ComfyUI pipelines, and game UX
- Building in public under the

| Area | What I am building |
|---|---|
| On-chain apps | Farcaster miniapps, Base ecosystem tools, wallet-aware UX, and live contract integrations |
| Games | PurrFarm — cozy farming loops, Web3 primitives, and mobile-first game UX |
| AI tooling | Local AI workflows, ComfyUI interfaces, MCP-assisted development, and agent-ready pipelines |
| Developer resources | Reusable guides, templates, and toolkits for builders working with games, Web3, and automation |
| Project | Description | Stack / Focus |
|---|---|---|
| isometric-game-skills | Agent-ready toolkit for isometric game systems, sprites, terrain, and pipelines | Python · ComfyUI · Game Dev |
| Base Checker | Base wallet scoring and miniapp-style wallet analysis | TypeScript · Base · Farcaster |
| Purr-Verify-MCP | MCP workflow support for repo verification, proof capture, and agent-driven checks | MCP · GitHub · Automation |
| Purr-github-MCP | GitHub-focused MCP workflow for cleaner repo operations and agent-assisted development | MCP · GitHub · Developer Tooling |
I prefer shipping small, real, testable iterations over polished mockups. Most of my projects are built around live integrations, practical UX, and reusable infrastructure that can survive beyond a demo.
I care about clean product direction, minimal fake data, real wallet flows, mobile-first UX, and tooling that helps builders move faster without hiding the actual engineering work.
