I'm a Boston University Computer Science alumnus and an AI Agent Engineer building reliable agent systems and production-ready AI applications.
My work spans:
-
Agent systems: orchestration, tool use, skills, context, and session management
-
Reliability: automated evaluation, regression testing, observability, and failure recovery
-
AI applications: voice-first products, browser agents, desktop apps, and full-stack delivery
-
Engineering: Python, TypeScript, FastAPI, React / React Native, Electron, PostgreSQL, and Redis
-

I contribute upstream fixes around reliability, security, and cross-platform desktop behavior.
- MetaBot — merged fixes across direct-message invariants, skill bundle safety, managed-file path traversal, and installer state.
- t3code — merged fixes for stale OpenCode model restoration (#4095) and Windows desktop scrollbar / resize-edge behavior (#4097).
