Sefik Mujkic is a Sarajevo-based product and UX designer with over 10 years of experience crafting digital tools for startups, enterprises, and B2B/B2C platforms.
He champions a research-led, human-centered process rooted in informed decision-making and systems thinking.
Sefik has led transformative projects like Symphony AI’s retail execution platform (boosting on-shelf availability by 11%), the AI-powered Siena support agent (driving $0 to $1.7M+ ARR), PIMCO investment tools, and digital services expansion for PetMeds (enabling 40% faster sales cycles)
Often working solo or leading small collaborative teams, he blends strategic thinking with interactive design and user insights to shape products people want — especially for early-stage ventures and non-profits that may lack internal design teams.
