Mariia K.

Hey there! I'm Mariia, a UI UX Designer and skilled frontend developer with 6+ years of proven success in design. With a blend of creative vision and technical expertise, I specialize in crafting modern, trendy and user-friendly designs that help your business grow. 🛒 DTC & eCommerce Expertise - one of my main specializations: I've worked as the lead UI UX Designer for a DTC supplement brand, which means I know direct-to-consumer growth from the inside, not from theory. I've designed and iterated high-converting PDPs and landing pages, led a full site overhaul and rebrand (structure, visuals, copy direction), built email campaign creatives in Klaviyo, and produced performance-driven static ads for Meta — UGC-style, problem-solution, social proof, comparison and product benefit angles. Every one of those was designed against a performance target, not a brand deck: I ran research and A/B tests, read the results in Google Analytics, Hotjar and Amplitude, and fed what worked into the next round. I'm equally comfortable working inside a locked brand system or building one from scratch, and I design natively for Shopify, Replo and other eCommerce platforms. 🏆 As a UI UX Designer, how can I help your product succeed? 🔹 With 6+ years of commercial experience in UI UX Design, web design, and mobile app design across SaaS, DTC, CRM, ERP, medtech, fintech, wellness, eCommerce, and enterprise platforms. 🔹 Accessibility-first UI UX Design.
