I originally (and always will be) was a C programmer, wrote my own relational database from scratch in C, and then in about 2018 began serially investigating Redshift sub-systems full-time, to write a book. That book became this web-site, where I publish my investigations, and ongoing cross-region benchmarking and version tracking and so on.
