Ria Walla

I am Ria Walla, a digital marketing student at Algebra University, currently in my 3rd year of studies.

My journey in the world of marketing began in the student association “Economic Clinic”, where I was part of the Marketing&PR team. After that, I joined 404 Agency as an intern, and I am currently in the Brand Communication department of the Degordian agency as a Social Media & PR intern. In addition, I lead the TikTok team at the University of Algebra and work as a demonstrator in some of the courses in the 2nd year of undergraduate studies. And when I’m not studying or working, you can find me competitively dancing or planning my next trip.
