Staff-level frontend engineer with ~12 years of building web products. I work on frontend architecture: component systems, monorepos, performance and accessibility. I also lead teams and build AI-powered product experiences.
- 🏗️ Led the frontend for a conversational assistant: streaming bot responses, rich action cards, in-chat webviews for web, Teams and Slack, and bot-to-human handoff
- 🧩 Moved a fork-a-new-copy component culture to one shared library: deprecated and removed v1/v2/v3 duplicates, and built an MCP-based Figma-to-code pipeline that reuses it
- ⚙️ Migrated Webpack 4 → 5 with codemods and cut tech debt by ~75%
- 👥 Managed pods of 5–6 engineers for 5+ years (hiring, reviews, promotions) and kept ~80% of the original team through my tenure
| Project | What it is | Under the hood |
|---|---|---|
| BecauseILiked | Tell it what you loved and why; get films, shows, books and games back with a reason each one fits | Next.js, Supabase + pgvector, embeddings + RAG with streaming LLM explanations, ~13.8k-title catalog |
| Thumbline · repo | Upload a song clip, get fingerstyle / arpeggio / flamenco right-hand sheets at three skill levels, with playback | Nx monorepo, audio processing to notation |
| VitalDelta · repo | Turns lab reports into trend charts, so you can show your doctor how your numbers move over time | Local-first: reports never leave your device; Chart.js |
I contribute to UI libraries, state managers, routers and design tools: accessibility, correctness and API work, each with a root cause, a failing test and a reproduction.
