Tomasz Bujnowicz
Senior Shopify Plus Developer at DTAILS
Background
I've spent my whole career building for the web — the last decade of it in e-commerce. Before e-commerce, I worked on digital projects for enterprise brands — Novo Nordisk, Lancome, Paco Rabanne, Autodesk, GSK, Casio, Jabra, DSV — which is where I learned to ship under real constraints: strict brand guidelines, multi-market rollouts, and teams spread across time zones.
When I moved into e-commerce, that enterprise discipline came with me. At DTAILS, I build storefronts for some of Scandinavia's biggest Shopify Plus merchants — premium fashion, beauty, and lifestyle brands that need more than a template can deliver. Before that, I worked with high-traffic stores like Meshki and 1212 Gateway, and dozens of other Shopify Plus merchants across the US, Australia, and the UK.
Based in Poland, working remotely with teams across Scandinavia and beyond. Previously lived on La Palma in the Canary Islands — until the volcano erupted in 2021.
AI is central to how I deliver at this scale — and it goes well beyond chat-assisted coding. I've built an agentic development environment around Claude Code: MCP integrations for Figma and browser testing, custom skills for scoping, shipping, and code review, and automated QA gates on everything it produces. I write about this on the blog because most Shopify content is either beginner tutorials or agency marketing — I wanted to share the practical, technical content I wish I'd had when I was figuring things out.
Outside of client work, I help maintain the site for the Charlie Cart Project — a nonprofit that teaches kids to cook through mobile kitchen carts in schools, libraries, and food banks across the US. Small contribution, great mission.
What I Do
Custom Theme Development
Full custom Shopify themes built for performance and merchant flexibility. No page builders, no bloat — storefronts that score high on Core Web Vitals and are easy for merchants to configure.
Complex Feature Builds
Product configurators, dynamic filtering, advanced cart logic, B2B pricing, multi-variant selectors — the features that require deep platform knowledge and architectural thinking.
AI & Data Readiness
Most Shopify stores are invisible to AI agents because product data lives in template logic instead of structured fields. I restructure the data layer so AI can actually discover and recommend products.
AI-Augmented Delivery
I run development through an agentic environment built around Claude Code — MCP integrations for Figma and browser testing, custom skills for scoping and code review, automated QA gates on everything that ships. Complex features delivered in days, reviewed at senior standard.
