I lead engineering, data & product at atm.com

I also spend a lot of my time working on on data tools

• Sidequery
  • a collaborative web & macOS data analysis and visualization tool with SQL notebooks & beautiful charts
    • Compatible with Claude Code, Codex CLI & Gemini CLI & your existing AI subscriptions
• pynb
  • a macOS native alterantive Python data notebook that is semi-compatible with Jupyter

Making analysis more reliable for both humans and machines is my passion!

Python Packages

• dlt-iceberg: a dlt destination for Iceberg REST catalogs (Nessie, Lakekeeper, Polaris, Glue)
• Sidemantic a multi-format metrics layer for Sidequery (and others!) to define reusable metrics to be used across analysis tools
  • Supports metrics in LookML, MetricFlow, Cube, Superset, Rill, Omni, Boring Semantic Layer Snowflake Cortex, Hex & Malloy formats
  • Works with DuckDB, MotherDuck, PostgreSQL, BigQuery, Snowflake, ClickHouse, Databricks & Spark SQL
• sqlmesh-openlineage: OpenLineage instrumentation for SQLMesh

DuckDB extensions

• acp: an Agent Client Protocol client that exposes a table function & parser extension to support querying with Claude Code, Codex, etc.
• poached: a utility extension for building IDEs on top of DuckDB
• yardstick: an implementation of Measures in SQL (arXiv:2406.00251)

AI Agent Tools

• memex: a CLI and agent skill for indexing and searching Claude Code + Codex CLI transcripts.
• agentexport: a CLI, agent skill & hosted API for exporting the current Claude Code + Codex CLI conversation to a public share URL. End to end encrypted!
• Ghostree: a fork of Ghostty with git worktree management integrated
