“I had the pleasure of working with Sebastian on several projects at Codelitt. His strong team-oriented mindset stood out—he consistently reached out across departments to align his designs with broader goals. Sebastian actively sought feedback, led brainstorming sessions, and skillfully integrated diverse perspectives into cohesive designs. His dedication to the team's success greatly impacted our project outcomes. I would gladly work with him again and believe he would be a valuable asset to any team.”

“Sebastian is a very proficient designer who demonstrated his capabilities through the quality of his design work. He is an all-around Product Designer with skills spanning from strategy to execution, from systemic design to implementation, from brand to atomic design. His experience is demonstrated not only in his deliverables but also in his attitude and extreme maturity to understand user needs and business drivers—a resilient person who gets things done by involving his team and clients.”

“Sebas is the kind of product designer that you'd like to have on your team. He's a smart, thoughtful person that never shy's away from doing the leg work necessary to get the job done. He's a proficient designer with great experience in most stages of a product's life-cycle (from early stakeholder interviews to wireframing the experience and managing a design system). He will take on any challenge with resilience, courage, and a sense of humor.”

“I've had the chance of working with Sebastian for many years in multiple projects. Each projects was in a different industry, and Sebastian never ceased to amaze me. His design systems are top notch. He works hard to really understand the problem he is solving, and solves it the best way.
Sebastian is very organized and communicates very well. It was a pleasure working with him and I do hope to have the chance of working with him again soon.”

“I worked with Sebastian on a multi-month software project, where he was the lead product designer on the project. Working with Sebastian was a great experience - he's a detailed, collaborative designer with a knack for breaking down problems and creating simple solutions to them. The project we worked on was a relatively short timeline, so simple solutions were key, and he did a great job of understanding the user need behind a feature, collaborating with the engineering team to make sure his solution was right-sized, and presenting our proposed solution to the client. He went the extra mile on the project as well, helping out with QA and user onboarding documentation, which I really appreciated as PM of the project. He's a good communicator, adaptable as requirements change, and diligent in his designs - I'd gladly recommend Sebastian to any teams in need of product/UX design.”

“Working with Sebastian has truly been a pleasure. He brings a strong design vision, deep knowledge of design principles, and an incredible ability to communicate and share ideas with the team. His understanding of the importance of design systems, and his collaborative approach to implementing them across design, product, and development teams, sets him apart.
Sebastian always adds value to any meeting by bringing potential solutions or sharing best design practices—you can count on him to elevate the conversation. And beyond his design skills, it’s his genuine humility and eagerness to help others that makes him such a fantastic teammate. No ego, just dedication and a passion for great design.
Anyone would be lucky to have Sebastian on their team!”

Apart from being a great designer, Sebastian is also an incredible team player—always ready to lend a hand, eager to learn new things, and constantly bringing fresh ideas to the table.
If you’re looking for a product designer who’s creative, strategic, and a genuinely great person to work with, I can't recommend Sebastian enough.”
