Senior Full-Stack Engineer

I'm a senior full-stack engineer, front-end focused, with 6 years building production web apps in React, Next.js, TypeScript and Node.js. I care about design systems, accessibility, pixel-perfect UI and AI features that stay reliable in production.
What I do today
At SQLI I lead the front end of IPCOM's new headless B2B e-commerce platform for the Netherlands and Belgium: a Next.js storefront on a BFF over Payload CMS, Strapi, Vendure and an ERP, with around 165 UI components, 2,800 unit tests and blocking CI gates on every merge. I defined the team's AI-assisted workflow with Claude Code and MCP, now behind about 90 percent of front-end commits, and I mentor a second front-end developer through daily code reviews.
Before that
Nespresso: over 30 Design System components for a global platform serving more than 40 markets, with zero confirmed axe violations.
Henko-AI: front ends for 10 AI products for TV, radio and digital advertising, shipping 5 voice-AI features with OpenAI and Whisper.
isEazy: evolved an LMS used by over 1,000 corporate clients and more than 10 million learners.
Freelance: production apps for more than 10 clients in tourism, hospitality and e-commerce.
Core skills
TypeScript, JavaScript, React, Next.js, Vue 3, Astro, Node.js, Express, GraphQL, REST APIs, Tailwind CSS, Storybook, Jest, Vitest, Playwright, AWS, Vercel, Docker, GitHub Actions, Claude Code, MCP and OpenAI API.
Beyond code
Background in medicine (MD) and in film as a director and director of photography, which is why I care about how real people use what I build.
