I'm a Shopify developer who specializes in theme customization — turning standard themes (mainly Debutify) into fully custom, conversion-focused stores. For the past 2 years I've worked across the Shopify ecosystem end-to-end. I managed live operations for 5-6 stores at the same time — handling orders, refunds, and customer support for 1000+ customers — while also customizing themes and fixing what wasn't working. That gave me a combination that's hard to find: I understand both the code behind a store and how real customers behave on it. Recently I've shifted fully into development. Some of what I've built: A kids' edtech Shopify store, designed and developed end-to-end, including 4 custom product pages with a bundle-purchase option A gamified video learning platform for that same brand, built with Next.js and Supabase — 10 interactive missions with progress tracking and certificates Full landing page and product page customization (Debutify theme) for a wellness brand and a spiritual journaling brand Daynode, a personal productivity app (Next.js + Supabase) that I built and continue to improve What I can help with: Shopify theme customization (Debutify and others, Liquid, custom sections/blocks) Custom landing and product pages built for conversion, including bundle/multi-product layouts Mobile-first responsive design Store fixes, performance and UX improvements Next.js + Supabase development for stores that need more than Shopify alone can do I'm also currently building out my UI/UX design skills. I respond quickly, communicate clearly, and treat every project like it's my own store.

In my 10+ years in the web field, I’ve worked with few designers who so accurately nail the brief. She combines creativity with reliable delivery and a strong understanding of the client’s needs, industry and audience, using data to inform her design decisions. Beyond the quality of her work, Kseniia’s process has been a real asset. She needs minimal hand-holding, is able to take a loose brief and shape it into something concrete, and consistently comes back with thoughtful options rather than just “pretty” designs. From initial concepts through to final assets, everything has been well-organised, documented and easy for me to work with. Reliability is a big factor for me, and Kseniia has passed with flying colors. I plan to continue working with her long-term, which I think is the clearest endorsement I can give. ⭐️⭐️⭐️⭐️⭐️ It was great working with Kseniia and the result turned out just as we wanted it to. Highly recommend. Thank you!
