David Tellis

I’m a customer-obsessed UX/Product Designer and Researcher with experience of 3 years, delivering 8+ MVPs and end-to-end design solutions across B2B and B2C platforms at scale.

I bring strong UX fundamentals—user research, usability testing, interaction design, and design systems—plus a foundation in front-end development that helps me collaborate effectively from PRD creation to implementation.

In my role as Product Designer at Turbostart (Venture Capital), I owned end-to-end design across multiple portfolio companies, built scalable design systems, and reduced design-to-dev turnaround by 30%. I drove measurable impact including 35% adoption lift and 40% workflow reduction, while leading user research, personas, and journey maps that shaped product launches.

I also leverage AI tools for rapid prototyping and micro-interactions, and I design responsive, pixel-perfect UIs for web and mobile with multi-platform accessibility and consistency (WCAG). I’m energized by diving deep into data, working backwards from customer needs, and shipping accessible experiences that raise the bar across cross-functional teams.
