About

I’m a Principal Product Designer with 10+ years of experience, working with startups and product teams to design and scale AI-driven, SaaS, and enterprise products. I help teams turn complex systems into clear, scalable user experiences — from early product discovery and 0→1 MVPs to Seed and Series A growth. My work sits at the intersection of UX strategy, UI design, and design systems. I focus on building products that are not only usable, but ready to scale — structurally, visually, and technically. I specialize in: – Design systems for SaaS and enterprise products – Complex workflows, dashboards, back-office tools, and AI interfaces – Product strategy, UX research, and cross-team alignment I’ve worked across fintech, healthcare, edtech, e-commerce, Web3, and B2B SaaS — often joining teams during high-impact moments: MVP creation, redesigns, and product optimization before or after launch. Certified in Interaction Design by Nielsen Norman Group (NN/g), I bring a human-centered, data-informed approach to every engagement. If you’re looking for a Principal Designer or Design Partner who can combine product thinking, UX leadership, and execution — let’s connect. 📍 Based in Ukraine · Open to remote work and relocation (US / UK) 🌐 dmitrysergushkin.com 📩 ux.sergushkin@gmail.com
