Over the past few years, I have collaborated with Karolina on several websites. I greatly appreciate her professionalism and expertise. Communication with her is always direct, factual, and effective. During our initial meetings, she often provides valuable insights and suggestions regarding specific solutions. Beyond clarifying the project brief, I never had to worry about any details—each site was delivered on time and with full functionality. What surprised me the most was the site’s performance. Although we didn’t explicitly discuss it during our requirements gathering, Karolina delivered perhaps the best-optimized site I have ever tested using Lighthouse. There are many more examples like this. Each project resulted in a well-crafted website that left me feeling that my investment was worthwhile.

Karolína was in charge of creating the website of our group of interpreters. She handled everything perfectly – from the graphic design to the site’s construction to the hosting. Communication with her was quick and seamless. All our requirements were met 100%. We are thrilled with the outcome and regret not utilizing Karolina’s services earlier.

What are they saying about me?
Karolína is a professional in the field. Not only she does have a great understanding of WordPress itself, but she can design solutions that you will appreciate. We organized the biggest WordPress conference in the Czech Republic together, and thanks to that, I know that I can rely on her 100%.

I contacted Karolína to revise a website’s status with a varied edits history. We deployed the website on a new template, got rid of unnecessary stuff, and made it faster. Karolína’s attitude was excellent. She dealt with every glitch and also devised several technical solutions that significantly improved the website. During the job, I understood that she understood her job damn well and gained maximum confidence.
