About Me
I am a Shopify developer and frontend web developer with over 5 years of hands-on experience building high-converting e-commerce stores and web applications for US and EU markets. My core strength lies in Shopify, including custom Liquid theme development, Shopify app builds, CRO strategy, and third-party integrations such as Klaviyo, DSers, and upsell tools.
On the frontend side, I work across the full stack using HTML, CSS, JavaScript, React, and Vue.js, translating Figma designs into clean, fast, and responsive interfaces. I founded and led my own web studio, managing projects and small teams end-to-end, which has given me a strong understanding of both the technical and business aspects of every build.
I focus not just on shipping code but on delivering solutions that move key metrics. For example, my stores have generated $5,000–$6,000 per month in profit, and a custom app I built in just 4 days increased average order value by 35%. I am available immediately, open to remote work, and actively relocating to Košice, Slovakia.
Throughout my career, I have architected custom Shopify and Headless Commerce solutions for international clients, built conversion-focused frontends with React, Next.js, and Tailwind CSS, and integrated complex third-party apps and APIs into Shopify environments. I have also managed contractors and handled project management tasks such as scoping, estimating, QA, and client delivery.
I am passionate about delivering high-quality e-commerce experiences and continuously improving my skills in both development and design to meet client needs and market demands.
