React

React is an open-source JavaScript library created by Facebook for building modern, dynamic user interfaces (UI) in web applications. Thanks to its component-based architecture and vast ecosystem, React is one of the most frequently chosen frontend solutions globally.

1. Component-based architecture – Enables building applications from independent, reusable components, facilitating code development and maintenance.
2. Performance via Virtual DOM – React optimizes interface updates using the Virtual DOM, ensuring smooth performance even in large applications.
3. Massive ecosystem and community – Access to thousands of libraries, tools, and support from the community and major companies.
4. Support for modern technologies – Integration with TypeScript, GraphQL, Next.js, Redux, React Native, and other tools.
5. Versatility – React can be used to build SPA, SSR (Next.js), and PWA applications, as well as mobile apps (React Native).
6. Stability and long-term development – The library is continuously developed and supported by Facebook and a broad community.

1. Learning curve – Advanced concepts (hooks, context, state management) can be challenging for beginners.
2. Frequent ecosystem changes – Rapid development of tools and libraries requires continuous knowledge updates.
3. No enforced project structure – React offers great freedom, which can lead to inconsistent solutions in larger teams.
4. SEO challenges in SPAs – Single Page Applications require additional solutions for SEO optimization (e.g., Next.js).

React integrates with numerous tools and libraries, such as Redux, Next.js, TypeScript, GraphQL, React Router, as well as backends (Node.js, Firebase). The React ecosystem is constantly evolving, offering support for modern frontend and mobile solutions.

• Vue.js: Vue.js is simpler to learn and deploy, but React has a larger ecosystem and popularity in large-scale projects.
• Angular: Angular offers extensive enterprise solutions but is heavier and harder to learn than React.
• Svelte: Svelte generates highly efficient code, but React boasts a larger community and tooling support.

•  Maintenance and development of IT systems (web applications, websites)
• Design and development work (creating new functionalities, expanding existing systems)
• User support and software engineering consulting
• Software quality assurance (testing, audits, optimization)
• IT project management (project leadership, consultations, workshops)
• DevOps services (server monitoring, updates, security, infrastructure maintenance)
• Design and implementation of dedicated solutions (including system integrations)
• Business and technology consulting (analysis, recommendations, process optimization)
• Post-implementation and service support (hypercare, rapid response to tickets, SLA)
• Graphic design and UX/UI services (for application and website development)
