David Ellis

I’m a software engineer in San Antonio, Texas. I build software to solve practical problems, working across backend, frontend, and infrastructure.

My personal projects include programming languages, parsers, and tools for working with data. This site collects those projects and my writing.

The name comes from my dislike of lawn work. Every time I finish mowing, I announce that I’ve conquered or vanquished the lawn.
