I created numerous websites using different technologies for the last 10 years.
I use Drupal CMS for content heavy websites with more than one authors. I created the old webpage of my department that I took my master's which is Istanbul Technical University, Architectural Computation. I also created the webpage of my research group in SUTD using Drupal, informeddesign.sutd.edu.sg:
I used Drupal for the old website for a media agency, kaset film.
I developed my professional website (this one) using Drupal as well. But I tried a few mock ups using React and Gatsby, you can see one in ozgunbalaban.com.
Lastly, I am the webmaster of Seltek Group's website, www.seltekgroup.com which is a cosmetics company that has an online store.
