Selected work

Sulo

My company

sulomotion.com
A picture board made in Sulo for a speech practice game Sulo's RTM billing screen with demo patients
What it is
A home exercise platform for pediatric therapy clinics. Therapists create illustrated exercises and picture boards in seconds, parents log progress from home, and the clinic sees how the week went before the next visit. It also handles Remote Therapeutic Monitoring billing.
What I built
The marketing site, the Expo mobile app and most of the internal admin tool, plus work across the React web app, the Node backend and the AI features.
Stack
React, TanStack, Tailwind, NestJS, Postgres, Claude and OpenAI models, AWS, Expo, Astro.

RenCaptur

Client work for a wound care company

RenCaptur web console patient list with demo patients
What they needed
Clinicians had to document wounds at the bedside, often without a reliable connection, and then review healing over time from the office.
What I delivered
The whole system, solo. A phone app for wound photos, measurements and dictated notes that works offline and syncs later. A web console for chart review, healing trends and team access. An admin tool to set up clinics. Access is scoped by role and by patient, and every export is logged.
Stack
Expo and React Native, Convex, TanStack Start, Claude, Docker on AWS.

SecretDocs

Client work for a wound care company

secretdocs.io
SecretDocs secure viewer showing a test contract with watermarks
What they needed
A way to share sensitive documents with staff without losing control of who sees them.
What I delivered
The whole product, solo. Documents open in the browser with watermarks. Organizations have roles and email invites, every request is checked on the server and backed by row level security, and an audit log records activity with search and CSV or PDF export. It now runs as its own product at secretdocs.io.
Stack
Next.js, React, Supabase (Postgres and Auth).
