Z Panem Danielem pracuję ponad 6 miesięcy. Wcześniej pracowałem z agencją. Muszę powiedzieć że jestem mile zaskoczony z obecnej współpracy. Znacznemu polepszeniu uległa jakość wykonywanej usługi, czas skrócił się o połowę a koszty spadły trzykrotnie. Z czystym sumieniem polacem Pana Daniela to bardzo kompetentny i uczciwy specjalista od Shopify.

Współpraca z Panem Danielem to naprawdę czysta przyjemność. Do każdej sprawy podchodzi bardzo rzeczowo, potrafi wprowadzić proces i urealnić efekt, który chcemy osiągnąć na naszej platformie. Dzięki jego wiedzy i doświadczeniu rzeczy pozornie niemożliwe stają się osiągalne. Pan Daniel doskonale wie jak działać w automatyzacjach, kodach strony i wielu innych rzeczach (aplikacjach, szablonach). Na szczególne uznanie zasługuje również sprawna komunikacja oraz nastawienie na efektywność działania. Polecam współpracę z Panem Danielem! :)

Dan has been a real asset in helping us navigate the backend of our Shopify site. He’s assisted with design adjustments, development work, and troubleshooting, and has been consistently responsive and thoughtful in his approach. We’ve appreciated his ability to understand what we’re trying to accomplish, the limitations of a small business, and to translate that into practical solutions without overcomplicating the process. Having someone reliable to turn to when issues come up or when we’re refining how the site functions behind the scenes has made a meaningful difference. Strongly recommended.

Top-notch collaboration! Communication was always fast and seamless, and the knowledge of Shopify was absolutely impressive – I received a clear and accurate answer to every single question. Task execution was lightning-fast, with no unnecessary delays. You can tell this is someone who knows the subject inside and out. I wholeheartedly recommend them to anyone looking for a reliable and highly competent specialist!
