A new type of command-line shell, written in Rust by an amazing team of top-notch programmers (and me). Check out the website to learn more about why Nushell is great; I think it’s a massive step forward from Bash and PowerShell.

I tend to focus on things like SQLite support, CI, and native Windows integration.

An experiment to see how far I can push a slim Windows application that uses C# for the hosting logic and web UI for the front-end.

I could embed web UI in a plain old .NET GUI app. But WinForms and WPF are big dependencies and they’re mostly unnecessary for web UI. Why not see how far we can get with an old-school Win32 message pump?

My personal music library system with a local-first Windows client and Linux server. It started out as a bored-during-the-pandemic project and now I use it daily.

The local-first functionality was a huge source of complexity; the library is essentially a distributed database that can be synchronized between any 2 clients (or a client and the server). But it works great.

Experimenting with better tooling for ad-hoc scripts written in C#.

C# the language is pretty succinct these days (top-level statements, global usings) but the project+build tooling still requires a bit too much ceremony. Here’s an attempt to fix that.

I wanted to explore UI ideas for ETL. Can we make complex data transformations as easy to use as spreadsheets? What if we had tools to quickly diagnose+fix common issues in data pipelines?

To answer those questions, I built an interactive prototype in React that parses JS formulas as they’re edited. More info here.

1. An Angular front-end that generates personalized letters in support of housing projects
2. A Serverless Framework back-end that uses Slack and AWS (Lambda, SES, S3, Athena) to review+send+analyze those letters

It’s been used over 1000 times, and most recently it was adopted by the BC Non-Profit Housing Association for their Build Homes Not Barriers campaign. More info here.

I built an interactive map of every property in Vancouver using Mapbox, Eric Fischer’s remarkable Tippecanoe, and a Heroku app to serve the map tiles.

Sadly, this died when Heroku’s free tier went away.
