I have spent the last few years working with the Magento 2 platform. Certificates prove my practical skills. I think that to get to know a good programmer, you should look at his code. Nevertheless, the certificates are an additional confirmation of skills.

Working with Marcin was a delight, and I truly hope that this was only one in many more opportunities to come in the near future. He is a talented Frontend Engineer (with strong UX and programming things understanding) and inspirational Team Leader, always willing to take on any task or help others with theirs. He is also a great communicator, collaborator, and extremely passionate about what he is doing.

I hereby confirm that Marcin Kwiatkowski has worked for us on various web projects in the field of coding websites. A fast growth of my company forced me to outsource some projects based on coding Sketch designs to HTML 5 / CSS 3 / jQuery. This is why I approached Marcin who has been successfully and efficiently providing support for our company INFIGO. Since Marcin is very flexible, our communication went smoothly from the very beginning and we have quickly found common ground. The delivered code meets my high expectations and Marcin has an excellent eye for detail, he's very accurate, and work according to web standards, such as W3C and WCAG. Additionally, all projects are done on time, within the previously specified deadline and budget. Therefore, I can sleep peacefully when we work together. Our cooperation brings satisfying effects and I hope to stay in contact with Marcin and keep receiving the high quality services he provides. I can sincerely recommend Marcin as a professional partner in terms of coding websites - front-end development.

Marcin Kwiatkowski offers a transparent system of cooperation and a flexible system of payments. I purchased the hourly packet and I am very pleased with that possibility. Every change on my website was first discussed and then, after implementation - detailed in a separate mail - report. With that, I knew exactly what I paid for and how many hours were left in the packet. In my case the entire cooperation was online, by mail and by telephone. When words were not enough, I received graphics with proposed changes, which was very helpful. It is noticeable that Marcin Kwiatkowski has a lot of experience and is well-oriented in newest trends when it comes to the graphic design and systemic solutions. My first website is for sure not the end of our cooperation.
