Work Experience
Staff Engineer in Developer Experience
Convex
- Built best practices for the Convex platform, codified in npm libraries like `convex-helpers` for, e.g., migrations, rate limiting, Zod, and sessions, along with blog posts on stack.convex.dev.
- Developed open-source local-first sync implementations for collaborative document editing, both as a sync protocol for Automerge and ProseMirror, powering apps like labs.convex.dev/jotion.
- Designed and implemented AI Town (convex.dev/ai-town) based on a research paper. It was a novel serverless game engine with AI agents talking and storing memories in relational database tables and a vector database in collaboration with a16z.
Contract Software Engineer
Curative
- Increased user features to find COVID-19 testing and vaccines locations on an interactive map and configure location info shown on a detail page.
- Improved the software and fixed the bugs by initiating research interviews with nurses and scribes who used the software on a vaccination site.
- Built back-end APIs and used React and TypeScript to contribute to the front end.
Contract Software Engineer
The New York Times
- Built a Slackbot prototype for public launch to improve user-sharing articles on Slack, with custom unfurl showing curated content and top links.
- Created a cloud pipeline and storage architecture to orchestrate compute-heavy conversions with a flexible API optimized for ML iteration speed.
- Collaborated with design, senior editor, copy, and engineers to communicate goals and progress frequently, adapting the scope while learning from each prototype.
Senior Software Engineer
Dropbox
- Designed and built micro-service infrastructure to preview user content, migrated all traffic with 10+ thousand RPS, and refactored and deleted legacy code to improve the new service's availability, extensibility, observability, and security.
- Led the team technically and stepped in as a manager periodically while producing more code than anyone on the team.
- Led the previews team for years while collaborating with numerous units, from features and emails for the photo-oriented Carousel product to the cloud document Paper product.
