Software engineer at IBM building developer tools, data APIs, and agent infrastructure.
PhD in Statistics & Computer Science. Former forensic statistics researcher. R package author and maintainer.
I build tools that help people see their data, and agents that help them act on it.
Right now I work on IBM's Developer and Operator Experience team, mostly around Langflow, the Astra DB Data API, document ingestion, and the practical edges of agent tooling: SDKs, MCP integration, model-provider abstractions, tool-use policy, and production ergonomics.
Before that I was at DataStax, Daisi Technology, and Omni Analytics Group. Before that, I did a PhD at Iowa State on statistical methods for matching fired bullets to the guns that fired them, using 3D surface scans, reproducible analysis pipelines, and statistical visualization.
- Langflow core - SDK and Flow DevOps API work, MCP auth resilience, provider cleanup, and the small reliability fixes that make open-source tools feel solid.
- Agent safety and tool policy - contributing to ToolGuard and bringing policy-aware tool use into Langflow.
- Document parsing and ingestion - integrating IBM's Docling into Langflow and Astra DB workflows so PDFs, Office docs, scans, and slides become useful context without bespoke glue code.
- Forensic statistics projects - occasional work on bullet-matching tools,
.x3ptopography, and browser-native visualization like Bullet Lens.
