Agent orchestration · AI infrastructure · fullstack products

I build AI-native tools and products by connecting the whole system: the model, the interface, automation, guardrails, and the person using it. 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: model routing, provider fallbacks, telemetry, and local-first workflows
• Voice-to-structure workflows: turning mental models into executable AI instructions
• Fullstack products with TypeScript, Go, Python, Next.js, and pragmatic data layers

These are floor values from a July 2026 verification, and still 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, security hardening, and CI. Full case study at the link.
• Bigswap v2: a Go and EVM event pipeline with RPC resilience, 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 thin wrapper that gives vision-less coding agents an image-understanding tool.
• Migrate: a scroll-driven 3D portfolio experience I built for a friend using Next.js, Motion, Lenis, and R3F.

These repositories are private; scope is shown here, and evidence is published as sanitized case studies on katsu.codes.
