I help Shopify store owners find and fix the hidden issues killing their conversions. Before I quote you a price, I audit your store and show you exactly what's broken — most stores I look at have 5-10 critical problems that are invisible to the owner but obvious to a developer. What I do: - Shopify store optimization (speed, SEO, mobile, checkout flow) - Full Shopify store builds and migrations - Custom Shopify app development (Liquid, React, Node.js) - Conversion rate optimization and A/B testing - Ongoing store management and monthly audits My stack: Shopify Liquid, Next.js, TypeScript, Tailwind CSS, Supabase, Vercel. Registered Shopify Partner. I also built and run a 15,000+ product discovery platform from scratch, so I understand ecommerce from both the dev and the merchant side. Based in the Netherlands. I work fast, communicate clearly, and deliver on time. Happy to do a free 15-minute intro call before any project to make sure we're a good fit.

I’m a musician, content creator, and freelance web developer with a strong focus on building modern, fast, and reliable websites using React, Vite, HTML, CSS, and JavaScript. My background in music and content creation has shaped the way I work: creative, detail-focused, and always looking for ways to make ideas feel clear, useful, and engaging. I love creating music, visuals, content, and digital tools that help brands communicate better and work smarter. Alongside web development, I also have experience with native iOS development using Swift and native Android development with Jetpack Compose, which gives me a broader understanding of digital products across different platforms. Recently, I’ve been focusing more on AI automation, workflow optimization, and internal tools. I’m currently using these skills to help run and improve a successful webshop, where I work on automation, website improvements, product content, and smoother internal processes. What I’m good at Modern web development with React, Vite, HTML, CSS, and JavaScript Custom dashboards and internal business tools API integrations and workflow automation AI-assisted tools for improving business processes Webshop optimization and digital operations Music production and creative content creation iOS development with Swift Android development with Jetpack Compose Clear communication and practical problem-solving How I work I combine technical skills with creativity. My experience as a musician and content creator helps me think beyond just code: I care about how something feels, how it communicates, and whether it actually works for the people using it. I use tools like Claude and other AI systems to speed up research, planning, debugging, content creation, and repetitive workflow tasks. But the important decisions, structure, creative direction, and final implementation are always reviewed and shaped by me. I like to work closely with clients to understand what they actually need, not just what they initially ask for. My focus is on building solutions that are useful, maintainable, and genuinely improve the way a business works. About me For years, I’ve been creating music, building digital products, and experimenting with new ways to combine creativity and technology. That combination is what drives me: turning ideas into something real, whether that is a track, a piece of content, a website, an automation, or a complete workflow system. My main goal is simple: to create practical and creative digital solutions that save time, improve workflows, and help businesses grow.
