LangChain, Software Engineer (Frontend)

New York · Jan 2026 – Jul 2026

  • Owned the frontend for LangSmith’s trace filtering redesign: saved views, filter chips, nested filters, keyboard navigation, and switching between traces and runs.
  • Shipped Messages View and Threads Unification, a conversation-style inspection view with tool calls, subagent calls, LLM call navigation, and links into run details.
  • Built React and TypeScript interfaces for dense traces: virtualized run details, metadata inspection, scroll restoration, and filter-driven debugging.
  • Worked with backend, product, and UX on streaming message APIs, filter actions, and SmithDB-backed trace queries.
  • Supported reliability through on-call triage, customer bug fixes, end-to-end test debugging, and feature-flagged rollouts.

Google, Software Engineer (Frontend)

Washington, D.C. · Oct 2021 – Apr 2024

  • Raised product click-through by more than 10% with shopping frontend work, including Brand Picker and a preference-driven product carousel, in TypeScript and Java.
  • Integrated backend APIs and tightened data-fetching so personalized shopping stayed fast at scale.
  • Designed and ran A/B tests on personalization.
  • Improved localization with tooltips, dynamic layouts, and automated title translation.

Novative Solutions, Software Engineer

Virginia, remote · Jan 2021 – May 2021

  • Built internal email and shipping services in C# and .NET.
  • Built React dashboards for inventory and sales, and moved UI templates across Angular, jQuery, and React.

Insight, Data Engineering Fellow

New York · May 2020 – Jul 2020

  • Built Living Insight, a full-stack platform joining NYC open data with simulated real-estate data, using Python, PySpark, PostgreSQL, and React.
  • Embedded Tableau dashboards in that React app for regional analysis.

Clinical Co-Pilot, 2026

Clinical Co-Pilot sits inside OpenEMR. The model proposes a next step. Code assigns a state: evidence found, order pending, no matching record, or records conflict. A missing record is never treated as not done. A later pass checks documents against the chart and shows a citation or unverified. A red-team report found four access-control bugs; after the fix, a deterministic replay failed. The report viewer cannot start a scan.
