React & TypeScript
React TypeScript Consultant for complex frontend projects
React and TypeScript are powerful, but in complex web applications the way you apply them decides whether a project stays manageable. Strict types, a deliberate component structure and a serious testing strategy are the difference between grip and chaos.
As a senior React TypeScript consultant I work on complex frontend projects: configurators, platforms and applications with a lot of state and logic. Hands-on in the code, with an eye for architecture, quality and the wider technical direction.
Where I help
React application architecture
Structure that scales with the complexity of your product.
TypeScript strictness
Strict typing as a foundation for maintainable code.
Component libraries
Reusable, documented components and design systems.
Complex forms & configurators
Deep dependency logic and validation, made usable.
State management
A predictable model with Zustand, TanStack Query or similar.
GraphQL / API integration
Type-safe data layers with codegen and strict typings.
Testing with RTL & Playwright
Component and end-to-end tests that actually inspire confidence.
Storybook
Components developed, tested and documented in isolation.
Performance
Targeted optimization and Core Web Vitals that hold up.
Refactoring
Paying down technical debt in a structured, safe way.
Not just code
A good consultant delivers more than pull requests. I also help with:
- Technical direction and architecture choices.
- Team agreements and standards that stick.
- Code reviews that raise the level.
- Quality processes and quality gates.
- AI-assisted development with senior control.
Relevant proof
The window & door configurator for Toelevering Online: a complex product configurator in React and TypeScript with a type-safe GraphQL layer, the URL as single source of truth, Storybook and a serious testing strategy. Two prior multi-developer attempts failed; I took it to live production as a solo developer, and the architecture has since been reused across the platform.
On top of that I led the frontend of a high-security communication platform for a government organization, and for 15 years at Media.Monks I gave technical direction to international teams on complex React/TypeScript projects.
