I’m looking for remote (EU) senior/staff frontend roles or freelance engagements where I can lead design systems and frontend architecture—improving maintainability, consistency, and long-term scalability. I enjoy partnering across teams and owning API contracts and integration workflows.
Darius Kruythoff
@dkruythoff
Senior Frontend Engineer specializing in Vue 3 design systems and scalable frontend architecture.
What I'm looking for
I’m a Senior Frontend Engineer with over two decades of web experience, primarily working as an independent contractor. I specialize in Vue since 2017, with a broader focus on frontend architecture and the platform beneath the framework—component boundaries, CSS architecture, API contracts, and shared infrastructure.
I’ve led and governed frontend platforms across multiple teams, aiming for maintainability, consistency, and long-term scalability. I standardize reusable component patterns to reduce duplication and accelerate feature delivery, while keeping complexity honest.
I also contribute across the stack when needed—designing and implementing API integration workflows (Node.js/Deno), supporting SSR/component-driven approaches, and strengthening testing and quality with Storybook and Vitest visual regression testing. I’m at my best building component systems and ensuring they hold up regardless of what tools sit on top.
