Developer tools for data teams

Serious tools for serious data.

I build database tooling for Netezza and SQL workflows — desktop IDEs, a VS Code extension, native drivers and fast spreadsheet libraries across .NET, TypeScript, Rust and Python.

02 / LIBRARIES & DRIVERS

The toolkit underneath.

Drivers, parsers and file-format libraries that power the apps — and stand on their own.

03 / STACK

Languages and platforms.

Native protocols over bridges: most drivers speak the database wire protocol directly.

03 / APPROACH

Clarity is a feature.

Database work is already complex. The tools around it should make state, intent and results easier to see — from the editor through drivers and SQL toolkits to spreadsheet I/O.

Context — schema-aware workflowsControl — explicit actions and feedbackContinuity — the editor stays the workspace
