My name is Casey Ydenberg and I have been building websites and web applications for over 11 years. In that time, I have built, maintained and deployed applications with a wide variety of different languages and technologies:

  • JavaScript ecosystem: especially TypeScript, d3, React and Preact, Node, and Deno
  • HTML/CSS, different CSS preprocessors and tailwind
  • Python: Django, Numpy, Biopython
  • PHP: Laravel and WordPress
  • MySQL and PostgresQL
  • NoSQL databases: especially CouchDB

See my full CV.

After multiple years of freelancing, I'm capable of covering the whole stack, although my deep expertise lies in crafting rich frontend experiences.

Prior to 2014, I was a research scientist. While I loved the lab, I discovered that I was better at communicating my work - both in person and in writing - than I was at actually doing it.

My passion lies in bringing these two career paths together: using web browsers to present complex science accurately and in a way which respects the principles of good user experience, responsive design, and progressive enhancement.
