Full-stack developer with 8+ years of experience in eCommerce and performance marketing. I build web applications, Shopify stores, and SaaS products using React, Next.js, Node.js, and TypeScript. As co-founder of a digital agency, I developed a SaaS platform (mojo) that increased repeat customer rates from 10% to 30-40%, launched a D2C brand with a headless GatsbyJS shop, and scaled ad campaigns to €100k daily spend across Meta, Google, and other platforms. What sets me apart is the combination of technical development and data-driven marketing. I don't just build — I understand the business side, from conversion optimization to campaign scaling. Whether it's a Shopify app, a full-stack web application, or integrating APIs like Shopify, Meta Ads, or WhatsApp, I deliver end-to-end solutions.
