At IBM

Core Langflow maintainer. Building agent tooling used in production.

Open source

Creator of Verity and Aeroza. Open, transparent, community-first.

Statistical rigor

PhD in Statistics & Computer Science. Forensic methods and reproducible analysis.

Location & time

Lake Stevens, Washington. Working across software, data, and decisions.

Selected work

Systems built to hold up under scrutiny.

Co-lead

Langflow

The open-source, visual framework for building AI agents. 147k+ stars. I'm a core maintainer.

I help shape Langflow at IBM, with a focus on agent tooling, MCP, the SDK, and the production details that make open-source software dependable.

Creator

Verity

Forensic surface comparison as calibrated evidence: transparent likelihood ratios — not black-box 'matches' — from 3-D scans of bullets, cartridge cases, and toolmarks.

An open forensic-comparison engine that reports calibrated evidentiary strength instead of hiding uncertainty behind a binary match.

Creator

Aeroza

Programmable weather intelligence: real-time radar, geospatial queries, streaming APIs, signed webhooks, and probabilistic nowcasting.

A developer-first weather platform for live radar, geospatial queries, streaming APIs, signed alerts, and public forecast verification.

Let’s talk

Let’s build things that stand up to scrutiny.

I’m always up for a conversation about AI agents, developer platforms, statistical graphics, or forensic statistics.
