VGI Injector: A Tiny HTTPS Download-and-Execute Binary in Zig

I needed a self-contained binary that downloads a program over HTTPS and exec's it — small enough to run in a FROM scratch container with nothing else. Go and Rust couldn't get small enough. Zig could.

Telemetry for DuckDB Extensions Without the Pain

I open-sourced the telemetry client I use across Query.Farm's DuckDB extensions. It's two files, one function call, and it only collects platform and version info.

Releasing vgi-rpc: An RPC Framework Built on Apache Arrow

I built an RPC framework for Python that uses Apache Arrow IPC as the wire format and Python Protocol classes as the interface definition. No .proto files, no codegen — just type annotations.

Acronym-Aware Case Conversions in the DuckDB Inflector Extension

The Inflector extension for DuckDB now supports configurable acronyms, so case conversions preserve terms like HTML, API, and URL as fully uppercase — configured through a native DuckDB setting.

What I've Been Working On

Full activity log →

I've been deep in infrastructure stewardship and ecosystem modernization over the past three months. February was a masterclass in coordinated upgrades—DuckDB 1.5 compatibility crusades across dozens of extensions, upstream Arrow enhancements across four language implementations, and shipping a complete production-ready vgi-rpc ecosystem with unified branding and documentation. The through-line has been taking mature projects to the next level: dependency management, cross-language standardization, and shipping polished developer experiences alongside performance archaeology and core database improvements.

  • Led DuckDB 1.5 compatibility across 40+ PRs spanning extensions like airport, shellfs, webmacro, and inflector while standardizing documentation across 29 repositories
  • Contributed upstream enhancements to Apache Arrow for custom metadata support in RecordBatch IPC messages and dictionary serialization APIs across JavaScript, Swift, Rust, and Go
  • Shipped Fair Weather Friend with PWA support, astronomical stargazing mode, and cycling/dog-walking specific weather features—transforming a utility into a delightfully practical tool
