## Summary

Tim has two live products that he built alone and still runs. VidlyAI is an AI video editor with about 3,000 sign-ups. Eventful is a multi-tenant event calendar SaaS. Before software, he spent almost 30 years in hands-on technical work he owned completely: Army biomedical equipment specialist, clinical engineer at Stanford, and owner of a motorcycle shop for 17 years.

In his own words: "I do my best work when I'm fully immersed in something and it's mine to own, and that's been true my whole career."

## Software projects

### VidlyAI (vidlyai.com): sole developer, Oct 2024 – present

An AI video editor that turns raw phone clips into captioned vertical reels. About 3,000 people have signed up.

- **Architecture:** Spring Boot/PostgreSQL API, React web app, Capacitor iOS and Android apps, and a Python video worker.
- **Pipeline:** nine stages. faster-whisper does word-level transcription, OpenCV tracks faces, and speaker detection combines mouth-movement scoring with a WeSpeaker voice fingerprint. Claude returns an edit decision list, which code validates against the source clips, with a safe fallback if the plan is bad. FFmpeg renders the result.
- **Edits without reprocessing:** each reel is stored as its edit decision list, so a user's edits re-render without re-running transcription or calling the model again. Cached render segments reuse unchanged work.
- **Reliability:** the API and worker communicate through a PostgreSQL job queue (FOR UPDATE SKIP LOCKED) with worker heartbeats and stale-job recovery. A reconciler fails stalled jobs and refunds the user's credit exactly once.
- **Deploys:** GitHub Actions, gated on 331 engine tests, with automatic rollback.
- **Audio:** RNNoise neural denoising raised the voice-to-background gap from 14.5 dB to 20.4 dB on a speech-in-crowd test clip.
- **Earlier feature:** an AI story feature produced more than 10,000 videos before it was removed.
- **Stack:** Java, Spring Boot, PostgreSQL, React, Capacitor, Python, faster-whisper, OpenCV, FFmpeg, Claude API.

### Eventful (useventful.com): sole developer, Jan 2026 – present

A live multi-tenant event calendar that a city or community group can embed on its own website.

- **AI flyer scanning:** upload a photo of an event flyer, Claude reads it, and the event form is pre-filled for a person to review.
- **Spam protection:** public submissions use a honeypot field, signed form tokens, rate limits, and an admin moderation queue.
- **Stack:** Next.js 16, TypeScript, PostgreSQL with Prisma, NextAuth v5, Claude API.

### Field Day: software engineer, ASU capstone, team of five, Jun 2024 – May 2025

An offline-first progressive web app for wildlife researchers running capture-mark-recapture studies in places with no connectivity. Sponsored by an ASU biology professor.

- **Stack:** React, Vite, Tailwind, Firebase/Firestore.

### Freelance web work

Websites and tech work for clients, including the City of Manteca.

## Career before software

- **Owner and operator, motorcycle shop (2002–2020).** Started it with no formal training, ran it for 17 years, then sold it to go back to school for software engineering.
- **Clinical engineer, Stanford / Lucile Packard Children's Hospital (1994–2001).**
  - Worked on an infant nitric oxide delivery system.
  - Assembled and calibrated medical device hardware used in a clinical trial published in the New England Journal of Medicine.
  - Later ran clinical engineering at Mount Zion Hospital as its only clinical engineer.
- **U.S. Army, Biomedical Equipment Specialist (MOS 35G), June 1991 – August 1994.**
  - First soldier to score 100% in biomedical equipment training, which led to an assignment at Walter Reed Army Medical Center in Washington, D.C.
  - Received two Army Achievement Medals.
