Agent orchestration · AI infrastructure · fullstack products

I build developer tools and products that connect a model, an interface, automation, and guardrails into one working system. I'm based in Surabaya, Indonesia, and open to remote junior or associate roles, paid internships, and collaborations.

• Agent orchestration with role-based subagents, ownership, audit gates, and constrained permissions
• AI infrastructure such as model routing, provider fallbacks, telemetry, and local-first workflows
• Voice-to-structure workflows that turn spoken ideas into instructions an agent can run
• Fullstack products with TypeScript, Go, Python, and Next.js

These are floor values from July 2026 and they keep growing. Current evidence lives at katsu.codes. Tokscale, 9Router, and other tool telemetry overlap, so they are not additive.

• EQ-Math: a deployed Indonesian math-learning product with role-based flows, strict TypeScript, SQLite, and CI. Full case study at the link.
• Bigswap v2: a Go and EVM event pipeline with RPC retry logic, scoring, Telegram alerts, and operational metrics.
• Spot Signal Lab: deterministic, paper-only research automation with Hermes cron jobs and SQLite FTS memory.
• Pi Vision: a small wrapper that lets coding agents without vision read images.
• Migrate: a scroll-driven 3D portfolio I built for a friend with Next.js, Motion, Lenis, and R3F.

The repositories are private. I show the scope here and publish sanitized case studies on katsu.codes.
