Design
Architecture, state machines, data models, service boundaries, and PRDs detailed enough for AI to implement correctly. UI design with Aura.build, Magicpath, and Kombai.

What I do
Build
AI writes the code in Qoder IDE, Factory Droid, Zed, or Windsurf (Devin). I review every line, security-scan it, and own the result.
QODER · DROID · ZED · WINDSURF (DEVIN)
Ship
Deployed web apps, a Flutter desktop app with 943 passing tests, and a filesystem daemon with 240 passing tests. All real codebases you can inspect.
VERIFY · TEST · DEPLOY
Four codebases worth inspecting.
ThumPiks
SaaS thumbnail studio: two editors — quick and full canvas — with twelve AI tools: model-tiered image generation, inpainting, face swap, auto-layer decompose, CTR scoring, and video frame extraction. Stripe and Polar billing on a credit system with a real free plan. Live in public beta at thumpiks.com.

gateINITIATIVE
Filesystem enforcement daemon for AI-driven development: watches every file change, evaluates it against gates defined in your own documentation, and alerts, logs, or reverts violations. IDE-, VCS-, and CLI-agnostic, with tamper-resistant state and ReDoS-hardened rule parsing. The case study covers the first audit it caught — in its own repo.

Asyndence
Desktop focus timer built around ultradian rhythms — it treats recovery as part of the work, not a failure of it. Guided breathing with ambient soundscapes; local-first storage with optional encrypted sync. BLE + HRV biometrics are built and tested — rolling into the guided recovery flow next.
943 TESTS · GITHUB / Asyndence
New Media Tek
B2B consultancy site I co-founded and built end to end: Astro 5 static shell, a custom visual CMS with live preview, and an AI chatbot capturing leads into InsForge. Security-hardened through a Playwright-driven audit — CSP, XSS sanitization, rate limiting, and two-layer prompt-injection defense with guard prompts held in Netlify Blobs. Pages degrade to hardcoded copy if the database dies.

Hi, I’m Kelly. Product Engineer in Honolulu. I design systems and use AI to build them.
Every project starts as a spec detailed enough for AI to implement. I make the architecture calls, AI produces the code, and I verify, test, and ship it. I do that with Qoder IDE, Factory Droid, Zed, or Windsurf (Devin) for code, Aura.build, Magicpath, and Kombai for design, and a local AI stack I run myself that powers Hermes and OpenJarvis, two agents I use daily.
Off-screen I experiment with plant-based recipes the same way I work through code: change one thing, test it, keep what works. I watch anime for the visual storytelling, which is where a lot of my UI instincts come from. I follow football for the chess match underneath the game, the schemes, the adjustments, and for the fun of watching with friends and family!
