React developers for complex digital products

Koodin provides experienced React developers who quickly understand how your frontend is structured, take responsibility, and contribute to a scalable application.

Senior React expertise when you need it

Experienced React developers for complex applications, digital platforms, and technical challenges.

Adding an extra frontend developer to a team is easy. Finding the right developer for a complex application is a lot harder. You are looking for someone who quickly understands existing code. Someone who can make decisions about component structure, state management, performance, and integrations. And who can work independently within an environment where quality, user experience, and maintainability are key. That is the type of React developer Koodin focuses on.

Our React specialists have experience with, among other things:

React
TypeScript and JavaScript
Next.js
Redux and Zustand
REST APIs and GraphQL
HTML and CSS
Component libraries and design systems

Jest and React Testing Library
Cypress and Playwright
Node.js
Docker and Kubernetes
Azure, AWS and Google Cloud
CI/CD and Git
Performance and accessibility

Schiphol

Schiphol worked with several digital platforms that did not align well technically and visually. Koodin helped with the development of a central design system in React, through which accessible, reusable components, consistent interfaces, and a uniform user experience across multiple platforms were realized.

How we contribute to your success

Koodin delivers senior React developers who build and continuously develop reliable, user-friendly, and maintainable frontends.

Nieuwe webapplicaties

A new web application, customer portal, or digital platform requires more than just knowledge of React. Our developers assist with frontend architecture, component structure, state management, API integrations, and testing. They help build the solution and ensure that it remains easily scalable and maintainable over the long term.

Modernisering van frontends

Many organizations have relied on Java systems for years. Replacing them is often costly and risky. Our developers modernize step-by-step: with upgrades, modularization, APIs, and detached services. We retain what works well and renew targetedly where it adds value.

Design systems en schaalbare frontends

Wanneer meerdere teams aan hetzelfde digitale product werken, worden consistente componenten en duidelijke afspraken steeds belangrijker. Onze developers werken met herbruikbare componenten, design systems en moderne frontendarchitecturen. Zo ontstaat een codebase waarin teams zelfstandig kunnen ontwikkelen zonder dat gebruikerservaring en technische kwaliteit versnipperen.

React development in cloud solutions

Moderne frontend development stopt niet bij de browser. Onze developers begrijpen ook hoe applicaties worden gebouwd, getest, uitgerold en gemonitord. Ze werken met CI/CD, containers en cloudplatformen als Azure, AWS en Google Cloud en kunnen goed samenwerken met backend-, platform- en DevOps-teams.

New applications

A new backend, API layer, or business-critical application requires more than just Java knowledge. Our developers assist with architecture, frameworks, integrations, databases, and deployment. They help build the solution and ensure it can be deployed to production in a manageable way.

Modernization

Many organizations have relied on Java systems for years. Replacing them is often costly and risky. Our developers modernize step-by-step: with upgrades, modularization, APIs, and detached services. We keep what works well and renew in a targeted way where it adds value.

Microservices and event-driven architectures

When applications grow and systems need to collaborate more, a microservices or event-driven architecture can help. Our Java developers are familiar with REST, Kafka, and distributed landscapes. Microservices are not an end in themselves: sometimes a modular monolith is a better fit. Senior developers recognize the difference and make conscious choices.

Java development in cloud solutions

Modern Java development doesn't stop at code. Our developers also understand what happens next: building, testing, deploying, monitoring, and managing. They work with cloud platforms like Azure, AWS, and Google Cloud, plus Docker, Kubernetes, and CI/CD. This is how they strengthen organizations where development and operations come together.
