Luka is a UX designer with 10 years of experience building digital solutions and more than 5 on mobile platforms. He has designed mobile and web solutions and led teams for clients ranging from small startups to large U.S. and EU companies with multi-million audiences. He is a Lean mentor and uses qualitative and quantitative research methods to validate assumptions and design products that achieve results and improve users' lives.
Redesigned a platform's business-facing app structure to clarify the conceptual model, redesigned the existing components, and designed new features to ensure usability and value for users (iOS and web).
Prioritized the design and development of the platform's customer-facing side, based on data analysis, to ensure product growth (retention and activation from AARRR model; iOS).
Researched user habits and based on insights, introduced simple personalization (context, history, and prediction) as the first step in increasing the retention and activation.
Optimized the team's process—improving speed and flexibility in the design phase (structure, symbols, reviews), and providing a clear input for the development phase (guide, specs, prototypes, & assets).
Initiated user research practice (direct bite-sized personal contact with customers through WhatsApp).
