Latest Updates



I've been reorganizing my code snippets repo, and among other things I've updated my dark mode support for modern SvelteKit.

This supports SSR by persisting both the user's choice and the default setting in cookies, to avoid that "flash of light". Check it out here.

I also set up CI and websites for PromptBox and sqlweld, where they can easily be downloaded.


  • AWS announced a new S3 storage tier designed for low-latency analytics among other things. If I ever start working on Projects/Smelter again this will be useful. 7x the cost of normal S3 but I'm sure that's worth it for certain systems.
  • Placekey looks like a nice solution for address entity resolution. It has a generous free tier and cheap paid tiers as well. Heard about it on from the Mapscaping Podcast.



Got the first version of Glance up and running. A bit more work to be done on design and then I'll be ready to write more mini-apps to feed in all the info I want to see... at a glance.



Spent some time yesterday and today updating my sqlx JSON companion crate to support sqlx 0.7. I also added a type that makes it easier to get a Box<RawValue> out of the query.

Also finally added tests! And wrote up some notes on using JSON in sqlx.

About Me


I'm currently taking some time off, but previously I co-founded and spent nine years working on Carevoyance (acquired by H1 Insights), a sales acceleration tool that analyzes healthcare data and enables healthcare sellers to zero in on their best prospects and generate custom reports and insights with just a few clicks.

I spent most of my time there creating new data analyses, working on the backend API and database systems, and developing tooling to research data anomalies and automate repetitive tasks. I also successfully transitioned the entire frontend application from AngularJS to SvelteKit.

In the past I worked almost exclusively in C++ and various assembly languages. Now that I'm more in the web ecosystem, I'm mostly writing Javascript for work, using Rust when I can justify it, and grudgingly dealing with Python's package system for AI/ML work.

Before starting my own venture, I interfaced with advanced network switching chips at Arista Networks and worked on JTAG hardware debuggers and embedded operating systems at Green Hills Software. Running a small startup feels very different from working at these companies, and it has its ups and downs, but I love it.


I usually have a few side projects going on, and I have a selection listed on my projects page. There you'll find a bunch of data workflow stuff, a personal dashboard, an AI assistant to amuse my kids, and other things in various states of done-ness.

Sometimes I wish I could code all day and night, but when not hacking on something or spending time with my family, I enjoy good coffee, nature photography, reading nonfiction and sci-fi, and improving my nascent design and UX skills. I'm also active in my church and run the sound board there every few weeks.
