Duncan Smith
I build apps for work that keeps coming back: finding information, reviewing recordings and keeping up with reports. By day, I work on quality systems for medical devices. I also help teams put private AI to work with their own documents.
Selected projects
SolScribe
Docker · WebFind what was said without replaying the recording.
Word-level timestamps take you back to the audio behind a passage in the transcript.
Prism
macOS · Windows · LinuxFind your notes, files and mail from one shortcut.
One shortcut searches fifteen sources, including files, notes and mail, and brings the results into one list.
16 projects, including Dolly, WinClip and Fluid Timer. View all apps →
Experience
I build and support my own apps alongside my work in medical-device quality systems.
Independent developer
Own products, alongside the day job
I design, build, ship and support my own software, from the database to the installer.
DeviceWatch
- Raises a critical alert as soon as a MAUDE report arrives that the FDA has coded as a Death, without waiting for the narrative or the AI analysis.
- Analyses up to 600 Death and Injury narratives a day in a single Message Batches call.
- Checks its audit chain every day, with immutable audit trails, access controls and session timeouts for Part 11.
- Publishes about 2,000 free stat pages for the top device categories and manufacturers.

SolScribe
- Transcribes 99+ languages with automatic detection, word-level timestamps and hallucination filtering.
- Ships a public multi-arch server image for amd64 and arm64. The same binary runs an MCP server.
- Writes each background job in the same transaction as its row, so a crash can't strand a transcription.
- The README lists every outbound connection a self-hosted server makes and what each one receives.

Prism
- Searches fifteen sources from one command palette.
