Computer science at Columbia University. I build backend infrastructure, observability, reliability, and data systems, with recent work across telemetry SDKs, MCP/agent tooling, data engines, API conformance, and CI.

53 external pull requests merged since July 2026.
| Project | Merged work | Impact |
|---|---|---|
| OpenTelemetry | Twelve JavaScript, Java, and documentation contributions | Corrects sampling and flush behavior, adds per-call timeout controls, documents exporter and .NET provider behavior, stabilizes benchmark CI, deprecates the OpenCensus shim API, and marks logger configuration experimental |
| Parallel Code | Sixteen merged improvements | Improves accessibility, review workflows, task coverage, UI reliability, and migration behavior |
| FINOS FDC3 | Eight conformance, documentation, and runtime fixes | Improves channel lifecycle behavior, error coverage, discovery reliability, and normal-scenario logging |
| CAMARA | Six API tooling and specification fixes | Strengthens OpenAPI linting, discriminator handling, notification conformance, access-token error guidance, version placeholders, and generated artifact stability |
| Polars | Two merged Rust fixes | Propagates the bigidx feature correctly and prevents a union-slice panic |
| Perspective | Persist datagrid column widths | Preserves plugin-owned column configuration across workspace save and first restore |
| FastMCP | Preserve raw CallToolResult returns |
Protects protocol-level metadata and structured tool-result semantics |
| Apache Arrow | Modernize Archery version handling | Removes reliance on a private setuptools_scm API and preserves release tooling compatibility |
| OpenInference | Four merged JavaScript and AWS SDK fixes | Enforces type-aware lint rules and prevents AWS SDK type-only imports from becoming runtime ESM dependencies |
