I build what I need.
Then I ship it.
Six products live across iOS, Android, and the web. Each one traces back to a real gap in a domain I actually live in — the clinic, the house, or the web.
A gap existed in accessible, portable clinical measurement tools. I built to fill it.
WristSkill
Wrist proprioception tracking had no lightweight, phone-based option — just bulky lab equipment.
Wrist proprioception assessment for clinicians and patients. Standard goniometers measure angle — WristSkill measures accuracy. Tracks six motion planes per hand with session history and baseline promotion.
AngleSnap
Clinicians measuring range of motion on screen had no purpose-built tool — a physical goniometer can't measure a screen.
Measure joint angles on any image or video in your browser. Click three points — proximal, joint, distal — instant reading: 55° (125°). All points draggable, nothing stored.

My family needed a better system than a whiteboard.
Shower Tally
LiveEvery family has a shower rotation problem. Nobody admits it. The whiteboard always breaks down.
A family shower tracker — the digital whiteboard your household actually uses. Every family member gets a card: Fresh ✓, Due Soon, or Overdue. Cards sort by urgency and sync across all devices via Firebase.
"Clean or not, the family knows."
Problems I kept hitting on the web — AI clutter, weak prompts, pricing games — each got its own fix.
WristSkill Labs Assistant
Every AI chat widget on the web ships your conversation to a server. This one doesn't have a server to ship it to.
An AI assistant that runs entirely in your browser — a deliberate tradeoff, not a ceiling. A compact 4-billion-parameter model runs on your own device via WebGPU, grounded in this site's content. Conversations never leave your machine; the only thing it ever transmits is a contact request you approve. The compact model — and desktop-first support — are the price of keeping it free to operate and private by design, chosen on purpose. The same architecture runs larger on-device or cloud-hosted models when a project calls for more.
SlopShield
AI-generated filler was everywhere — X, Reddit, LinkedIn — and it all looks the same at a glance.
Detect and filter likely AI-generated content while you browse. On-device AI via Transformers.js — no servers, no accounts. Four filter modes from subtle badges to full hide.
Promptello
Most people get bad AI results because their prompts are vague. Nobody has time to learn frameworks.
Turn rough ideas into structured AI prompts. Side panel picks the right framework automatically and drops the finished prompt into ChatGPT, Claude, Gemini, or Perplexity.
Prior Use Estimator
Used furniture and car listings are priced on feelings. Buyers had no data to push back with.
A negotiation aid for buyers of pre-owned furniture and cars. Describe the piece — or the car's odometer — and it produces a research-backed usage estimate with a confidence rating, plus a paste-ready negotiation brief to send the seller.
