Hi, I’m Simeon, a Staff Product Designer based in Varna, Bulgaria, specialized in User Experience for Enterprise Software.

15 years of Design. Creator. Family-centered.

Mortgage management

I led the design of this mortgage management platform, which streamlined complex loan processes for lenders and borrowers, improving user satisfaction and boosting overall efficiency by 40%.

Pre-employment screenings

I designed a pre-employment screening platform that enabled the client to increase workload capacity without expanding their team, resulting in new contracts and a 25% improvement in operational efficiency

I completely redesigned the tenant renting experience, reducing contract signing time to under 10 minutes, leading to a significant boost in conversion rates, accelerating new stock onboarding by 30%.

I had the incredible opportunity to work closely with Simeon on several initiatives, including our pioneering Gen AI features. He is not just an exceptional professional but also a creative individual with innovative ideas that truly stand out. He goes beyond just finding solutions; he delves deep into understanding the business and customer needs, analyzing every possible angle before arriving at the best approach.

His experience and deep knowledge of the product design process have consistently resulted in outstanding designs that meet both business objectives and user needs. Working with Simeon has been a pleasure and a fantastic learning experience for both of us. I highly recommend him to any company. He is a hidden gem, and any organization would be lucky to have him on their team.

I had the pleasure of working with Simeon for over two years at Quantive, where he served as a Senior Product Designer. He consistently demonstrated exceptional design skills, drive, and responsibility during this time. Simeon's dedication was evident when he successfully designed a new product experience from concept to completion, in just over six months that extended our main strategy execution software with AI-enhanced planning and decision-making capabilities. This achievement is a testament to his ability to manage projects independently and deliver outstanding results.

Throughout his tenure, Simeon was a cornerstone of our team. His vast experience and expertise were invaluable, and he was frequently sought after for guidance and recommendations by his peers. His collaborative spirit was particularly evident in his interactions with our engineering team, where he fostered a productive working relationship.

He’s always on track with the latest technologies and methods, and ready to share everything he knows with the team. His design process is a great example for the whole team. Simeon has all the qualities and energy to face any new design challenge. I’m thankful for everything I learned from him.

Simeon is one of the best designers I have ever worked with. He operates quickly and consistently produces high quality work. Most importantly, he productively challenges your assumptions about what your product should look and feel like. I hope to have the chance to work with Simeon again in the future. If you have the opportunity to hire him, do it.

Simeon is one of the best designers I have worked with in my career. I worked with Simeon for more than a year and he has the unique ability to design quickly in high fidelity. You can him a project scope and he'll come back a day later with thoughtful hi-fidelity designs. I've never seen anything like it. Most importantly, he always puts the user first and challenges my product-thinking with questions/feedback that make the team better. That's the type of communicator I want on my team. I hope to work with Simeon again.

I had the pleasure to work with Simeon on couple of apps that demonstrated key company technology. Simeon worked tirelessly with product and engineering departments to initially define and then refine the design. He is always striving towards perfection and the results are there. For our time together on the same project he not only showed deep understanding of UX and the product specific domain, but also excellent self-organization and helpfulness. As a mobile engineer I can say that Simeon made my job a breeze by making so many things clear and detailed in the app’s design. For my time in the industry it’s rare that I’ve worked with such focused and positive person.

Simeon was part of a small team at Smiley Media that built a social web browser application that generated 70k+ registered users from all over the world. Simeon was a member of the original team and about 90% of the user-facing designs were created by him. Before hiring Simeon, Smiley Media looked at the portfolios of literally hundreds of designers. We were truly lucky to have such an outstanding designer on our team.

Not only did Simeon deliver good work on time, the work he delivered was impeccably well organized. Thanks to this, the amount of time required for our dev team to apply design changes to the application was minimal and we were able to move quickly. Simeon was always very eager to take on complicated and involved tasks. And he *always* maintained an optimistic, positive attitude.

In addition, Simeon provided design change ideas to test in production. More often than not, the ideas Simeon suggested proved to increase user engagement and desired behavior - backed up by statistically significant data.

After 18 months of working with Smiley Media, the skill & devotion Simeon demonstrated made promoting him to Design Team Lead a very easy decision. I would certainly work with him again. I whole-heartedly vouch for Simeon’s professional and personal character. Honestly, he’s one in a million.
