At Etops, I redesigned core fintech interfaces to improve task completion speed and usability. I also systemized components and clarified design patterns to reduce UI inconsistencies.

At Globalcell, I led end-to-end UX/UI design for the eSIM platform across web and mobile. After redesigning the product experience and website, monthly sales grew from 40–50 to 100,000+, while task completion rose from approximately 15% to over 70%.

At Alphaling GmbH, I redesigned internal CRM-style tools, simplifying workflows and information hierarchy. I delivered UX/UI solutions from user flows to high-fidelity designs in collaboration with stakeholders and developers.

At Aniborgs, I designed a mobile-first NFT platform for web, Android, and iOS; UX improvements contributed to 67% growth in company funds during the platform’s expansion period. I also mentor women in Georgia transitioning into UX, supporting them with fundamentals, portfolios, and interview preparation.
