Hi, I'm Klara "Aster" Jarolimova and I am a product designer. My design journey began in childhood—building cityscapes between tree roots, sketching them to life, or prototyping board games to help runners train. Even then, I knew design was about storytelling, function, and connection.
That early passion grew into a mission to craft human-centered digital experiences. While traveling, I seek meaningful connections and draw inspiration from diverse cultures—reminders that true innovation is rooted in empathy and shared human stories.
Today, I bring that mindset into every project—from AI-powered healthcare and conservation tools to gamified platforms and enterprise systems. I've held roles across UX, UI, research, front-end development, and leadership—thriving in collaborative, cross-functional teams. Under Klarko, I provide UX strategy and product design for early-stage startups - turning scrappy ideas into scalable products.
I researched how AI-powered personalization and game mechanics boost engagement and inclusivity—especially for healthy and sustainable eating—on a patent-pending platform with a search and recommendation engine built into iOS and Android messaging apps. This concept explores how conversational interfaces can reduce social friction and decision fatigue within group settings.

After volunteering in a music and arts therapy program in Nairobi, I joined a humanitarian hackathon where I co-designed an AI-powered tool integrating sensory data with medical knowledge for personalized diagnostics. The project explored how AI can support collaborative decision-making between patients and physicians. Building on that, I’m developing a conceptual wearable-driven AI tool to reduce trauma-induced pseudo-seizures through therapeutic guidance.

Our team explored environmental challenges and developed a gamified, social tool to promote healthy, eco-friendly lifestyle changes through engagement and community support.
I expanded the study to explore how AI and AR can create immersive, personalized educational experiences that deepen awareness of nature’s role in enhancing mental health and inspiring sustainable, health-conscious living.
I collaborated with advisers from Rotary’s Cadre of Technical Advisers—a group supporting Rotary’s mission to eradicate polio—using user research and testing to improve the application and onboarding experience for new volunteers, such as doctors serving in refugee camps, supporting global health and humanitarian missions.
