Product engineering across AI automation, backend systems, native software, and interactive products.
Python and TypeScript · deterministic checks + AI assistance · local-first where it matters
Follow new projects and updates from @kiku-jw.
My recurring workflow is simple:
messy input → deterministic checks + AI assistance → report, repair, transcript, export, or control loop
I own the path from product framing to tests, documentation, deployment, and the final artifact a person can inspect.
- KikuAI — exploring the next narrow product around a recurring problem, an accessible first user, and a result that can be checked before the system grows.
- Hutmates — contributing to a team-built cooperative game across Unity/C# gameplay, physics, multiplayer diagnostics, QA, and presentation.
- Hourleaf: Ministry Hours — local-first ministry time ledger for iPhone and Apple Watch.
- FitKiku — read-only Apple Health connector for personal AI agents.

- StudyNav — Unofficial Study Tools — local-first study helpers for supported public JW.org and WOL pages in Chromium browsers.
- Page Media Downloader — Chrome/Brave extension for page-exposed images and direct media, without DRM or paywall bypass claims.
Store publication is evidence of shipped distribution, not a claim of adoption, revenue, or product-market fit.
- PATAS — audit-first pattern discovery and rule management for historical message and moderation exports.
- ReliAPI — retries, caching, circuit breakers, rate limits, and cost controls for HTTP and LLM workflows.
- ClipStash — native local-first macOS clipboard history utility in Swift.
- Untwine — deterministic diagnosis and safe repair for Articulate XLIFF import failures.
