Open source

Open source is part of my day-to-day work: maintaining my own tools, trying them in practice, and contributing improvements upstream. Early experiments and visualizations live in Labs.

Dotfiles

Actively maintained

My everyday development environment

My largest ongoing personal open-source project is the environment I work in. These dotfiles bring together Neovim, tmux, zsh, terminal tools, and coding-agent configuration across macOS and Linux.

I keep improving the small things that shape a working day: finding information, moving between sessions, carrying configuration between machines, and giving agents consistent instructions. A Makefile installs the configuration and converges the tools toward the setup I use.

This is an opinionated personal environment. Read the installation steps and scripts before applying it to your own machine.

Viewrule

Experimental

Used on this website

How do you give a coding agent useful design boundaries—and check whether its UI stays within them?

Viewrule combines written design rules with executable browser checks for layout, density, context, and accessibility. It captures both page overviews and native-scale detail so large screens do not conceal small defects. Agents receive findings tied to the rules; human feedback helps refine the constraints.

It includes a CLI and a Claude Code plugin. This website uses it to check its rendered pages. Passing those checks means the configured constraints passed; it does not establish that a design is good or automate every accessibility judgment.

Selected open-source contributions

Selected changes to tools I use, alongside earlier foundational work. Dates indicate when changes landed upstream, not ongoing maintainership or release availability.

bqls

Merged

Added type details to completions and richer field and table hovers in this BigQuery language server. Fixed completion panics on unfinished queries and false diagnostics for timestamp parameters in snapshot queries.

Typed completions and query diagnostics

hotreload.nvim

Merged

Replaced interval polling with filesystem-event watchers and limited watching to visible buffers in this Neovim plugin.

File-watching improvements

focus.nvim

Applied upstream

Added terminal-size thresholds that choose equal-sized Neovim splits on larger terminals and give the focused window more space on smaller ones. The maintainer applied the change directly with my authorship preserved; the pull request was closed rather than merged.

Adaptive split sizing

Original pull request

umya-spreadsheet

Merged

Made the defined-name setter public so dependent Rust crates can create and rename Excel-style named ranges.

Public named-range API

copilot-api

Merged

Preserved Anthropic thinking content as text when translating messages to the OpenAI-compatible API, fixing malformed requests that returned HTTP 400 errors.

Thinking-block translation fix

jnv

Merged

Added configuration-file support for custom keybindings and styles, using the XDG configuration-directory conventions.

Configuration-file support

Sinatra

Merged

Changed default parameter escaping in the bundled rack-protection integration and added a regression test. Both changes were merged upstream.

Parameter-escaping fix

Regression test

fog-aws

Earlier foundational work

I helped get fog-aws started: a Ruby library for working with Amazon Web Services, usable on its own or through Fog. The project lists me as an author alongside Wesley Beary. My involvement was in its early development; I have contributed little in recent years.
