“Working with Sovol and Miloš was such a great experience
They deliver what they promised and they even over deliver
I love that they communicate, so you know where you stand, and you understand what you can expect.
the quality of things they produce is just amazing too!
Sovol is very creative and branding is his strong suit
While Miloš is technical yet still with a designer background which creates such a perfect combo.
Absolutely great people to work with, they are professional professionals, and take their job seriously.
Would 100% work with them again🙏🏼”
Mila PavlovaClient Success & Project Lead, New Designers
“Every once in a while you find someone on Upwork that not only does a great job, but is also very enjoyable to work together with on a project. Milos fits this perfectly. He delivered everything we requested with high quality and fast turnaround. We will certainly be happy to hire him again on future projects. Our requirements were difficult and he did an excellent job in completing the task creatively. He did everything and made it a fun process. Thanks again!”
Joseph EpsteinCEO, Wonderful Dental
“I had the pleasure of supervising Sowol during his graduation internship at Studio Vi. He impressed me with his strong visual design skills, strategic thinking and genuine curiosity. He combines thorough research with creative ideas and consistently translates them into polished, practical outcomes. Throughout our collaboration, Sowol became a highly independent and reliable designer who took real ownership of his work and responded thoughtfully to feedback. His branding, digital designs and UX work delivered lasting value to our team and were implemented in real projects. He is also a friendly, helpful and dedicated person who is a pleasure to work with. I would gladly recommend Sowol to anyone looking for a thoughtful, talented and dependable creative team member.”
Sam de VriesDesign Lead, Studio Vi
“Milos took on a project that another freelancer was overwhelmed with. He completed the task 100 % and I am happy with the result. His English level and programming skills were very good. I will definitely hire Milos again.”
Marian HarderFounder, Ekarian UG
“Miloš is truly a rare gem. Extremely passionate about his work and very eager to learn. He is a real jack of all trades, UX, front-end, back-end, he is proficient in all of those. Miloš has impressed me many times, both as my student and my colleague at New Designers. The speed in which he learns new things and gains deep understanding of a new subject is something I don't see very often.”
Wouter van den HeuvelTech Lead, New Designers
“I had a great time supervising (or rather, work together with..) Miloš during his graduation internship at E-Flight Academy. I handed him a problem that had defeated several students before him: redesigning our flight booking system. It looked simple from the outside, but underneath it was a maze of real operational constraints: weight limitations, restricted instructors, late-cancellations, charging schedules, peak hours, aircraft in maintenance, and several invoicing flows all tangled together. What set Miloš apart was how he worked. He didn't get stuck at desk research. He went straight to our operations team, instructors, and students, proactively, again and again, until he genuinely understood how the system needed to work in practice. Next to being a great designer, Miloš has strong technical skills and was a great help in setting up the system technical architecture. During his project we already implemented most of what he delivered and expect to use essentially all of it: a significant improvement on what we had. Smart, independent, technically strong, and genuinely good with the people around him. Would I hire him? Without hesitation. Any team would be lucky to have him.”
Matthijs CollardCo-Founder, E-Flight Academy
“Would highly recommend Milos. Fast learner, can operate in non structured/growing environment.”
Amy KleinChocolate Executive, De Bonte Koe
“I had the pleasure of coaching Miloš, and from day one, his energy and dedication stood out. He was always the first to show up, and his positive attitude made a real difference in the team dynamic!
Over our time working together, Miloš made incredible progress in both project management and coding. He went from structuring his work more effectively to leading key aspects of projects with confidence. His ability to break down complex problems, stay organized, and push forward, even when things got rough, was truly impressive.
What I admire most about Miloš is his eagerness to learn and grow. He’s not just looking for quick solutions, he’s invested in understanding the bigger picture and improving every step of the way. I have no doubt he’ll bring this same drive and enthusiasm to any future challenges he takes on.”
Andreas Kruszakin-LiboskaDesign Engineer, New Designers
“We've been working with Miloš on several projects, and we are very happy with his services.
He is prompt and very involved.
What stands out to me is the thoughtful approach throughout the process.
Instead of simply executing the brief, Miloš takes the time to flag design issues and alignment inconsistencies along the way. His willingness to question, reflect, and apply critical thinking ultimately improves the final outcome.
I truly value partners who don’t just follow instructions but actively contribute their expertise to make the work better. This level of care and professionalism makes a real difference.”
Corina CulevaFounder, Zoe Rowyn Bridal
“My experience working with Sowol was so joyful! I contacted him so we can work a brand style book for a project i had in mind. And i have to say, from the beginning to end he asked the right questions, listen carefully and developed concepts and ideas with patience until we arrived to final form. It was smooth, and original! I trust on his skills and creativity as such point that some of the ideas I wasn’t considering as “solid” made it to the final design work purely because he adapt the concept smoothly. I would recommend working with Sowol to anyone who wants a smooth and nice creative process with a talented human being. He guided me all the way! He listened, if I have questions he was patient and took the time to explain, and if there is anything in the process that feels like is not working he manages to find a path and deliver some sleek concepts, taking the time to draft original proposals that are based, with patience and charisma! I would definitely love to work with him again!”
