CV
My name is Oleksandr Bielinskyi. I am the founder and CEO of Room15.Digital and SportStuff.com.ua, a lifestyle store for active people.
My core principle in work is simple: I do not aim to just meet expectations — I aim to exceed them. This applies both to my own standards and to the expectations of our clients. I believe this is what helps build strong partnerships and create results that genuinely move people and businesses forward.
For me, every project is a new challenge and an opportunity to grow. I pay attention to the details, take responsibility for the outcome, and see every task not just as work to be completed, but as part of a larger path of development.
A thoughtful approach, clear processes, transparency, and responsibility for the result are the foundation that turns ideas into real achievements.
Room15 Digital was built on these values — as a team that creates digital solutions capable of improving businesses and opening new opportunities for growth.
About Room15 Digital
Room15 Digital is an eCommerce Scaling Partner from Ukraine.
Since 2019, we have been providing technology solutions for eCommerce businesses of different sizes and levels of complexity.
Our team is based in Dnipro, Ukraine, and includes experienced product managers, business analysts, CRO designers, web developers, QA engineers, and DevOps specialists.
Over the years, we have delivered 150+ projects, built 15+ long-term partnerships, and gained more than 7 years of practical experience in digital product development.
Our Expertise

This gives us a practical understanding of what an online business really needs: traffic, conversion, product structure, catalog growth, analytics, automation, stable infrastructure, and long-term scalability.
At the core of our approach is CRO based on the ESR model — gradual, systematic improvement of website conversion. We also build clear SLA processes and support SEM promotion across SEO, AEO, GEO, SERM, and Local SEO.
Whether you are a startup or an established company, we help create the technical foundation for your digital growth.
