David Kellum, a software engineer, web content, database and search technologist currently based in Seattle, WA. Random photograph at right, so you can find him in a national park or coffee shop near you, post pandemic. Meanwhile, he can be reached via email to: dek@<here>.

As far as code you can look at, he started various open source projects over the years, and has contributed to many others. See SyncWrap for a take on nimble yet repeatable provisioning and deployment automation. Iūdex is a continuous/revisiting web crawler, feed aggregator and text processor. Most recently in the Rust language, see marked, body-image, blocking-permit, olio and tao-log.

He has also made contributions to: (Rust) Cargo, tokio, http, url, (Java) Jetty, JRuby, Rubygems, Bundler, Fishwife and Puma. These and other sources can be found on github.
