Independent software developer building privacy-friendly products for WordPress and the web

I'm Danny, founder of ibericode. I build and maintain software used by millions of websites, mostly in PHP, Python, SQL, JavaScript, HTML and CSS, with occasional work in Go, Rust and C.

Products

  • Mailchimp for WordPress: the #1 Mailchimp plugin for WordPress, actively used on well over 2 million sites.
  • Koko Analytics: lightweight, privacy-friendly and open-source analytics for WordPress. No third-party services.
  • ibericode/vat: PHP library for EU VAT validation and rates.

Open-source experiments

  • 1BRC: one of the fastest implementations of the 1 Billion Rows Challenge, in standard C99 with POSIX threads.
  • Nederlang: bytecode interpreter and virtual machine for a programming language with Dutch keywords, in Rust.
  • Advent of Code: solutions for 2015-2025, in C, Rust, Python, Go and PHP.

Previously

  • Fathom Analytics: I co-founded Fathom, built the original open-source version, and helped get the privacy-focused analytics business off the ground.
  • Browserpass: browser extension for pass using native messaging.

More code is in my GitHub repositories, and longer-form notes live on dannyvankooten.com.
