Frontend Developer at Uploadcare

It was a pleasure to collaborate on our @uploadcare/nextjs-loader with Konstantin. He is heavily experienced in Next.js and React stacks, keeping abreast of their updates. Knows everything about responsive images. It was easy to communicate with, and I felt like we were on the same wavelength. So I can highly recommend Konstantin for any front-end project.
