I'm Cas Zandona, a product designer helping brands understand the impact of advertising campaigns at DISQO.

Before, I was improving the payments workflow for creators and businesses at Lumanu.

For the last 8 years as a product designer, I've learned to:

  • Never take a problem at face value - Always question and dig deeper
  • Welcome feedback, pushback, and questions
  • Accept when you are wrong and be prepared to compromise

My process

Whenever a problem (or solution) is presented to me, I like to get familiar with the problem and the knowledge space. This helps define a better solution.

Throughout the process, I like to involve product and engineering, as well as any internal stakeholders who are invested in the problem.

Ideally, research is done for every project, but we know this isn't realistic. I find any other way to validate ideas - whether it's talking to folks internally, looking at data, or launching and measuring it's impact.
