React & React Native Developer

Building Dynamic, User-Centric React & React Native Solutions

Delivering Responsive, Performant Interfaces at Enterprise Scale

With extensive experience in React.js, Next.js, and React Native, I specialize in creating rich, intuitive user interfaces that drive meaningful engagement. By leveraging modern JavaScript (ES6+), TypeScript, and state management tools like Redux and the Context API, I architect front-ends that are both scalable and maintainable. My approach involves integrating best-in-class UI/UX practices—such as responsive design, code splitting, and lazy loading—to ensure lightning-fast load times, smooth navigation, and exceptional accessibility.

I adhere to Agile methodologies, employ test-driven development (TDD) using Jest and React Testing Library, and integrate CI/CD pipelines (GitHub Actions, Jenkins, Vercel) for streamlined, reliable releases. Whether optimizing performance with Next.js server-side rendering, enhancing SEO, or delivering cross-platform features with React Native, I bring a holistic, quality-first mindset. Let’s collaborate to transform your ideas into user-centric, high-performance interfaces that delight your customers and elevate your brand.

How may I help you?

High-Performance React Interfaces

From building single-page applications with React.js to architecting SSR experiences with Next.js, I focus on crafting front-ends that are not only feature-rich but also highly performant. By employing advanced techniques like code splitting, memoization, and Lighthouse audits, I ensure that every interaction feels fluid and responsive. CSS frameworks like Tailwind and Styled Components help maintain a consistent design language, while strict adherence to TypeScript and ESLint/Prettier standards keeps the codebase clean, reliable, and easy to scale. The result? Fast, intuitive interfaces that keep users engaged and satisfied.

Intelligent Data Integration

To handle complex data flows seamlessly, I integrate state management solutions tailored to each project’s needs—be it Redux for large-scale state orchestration or the Context API for lightweight scenarios. I streamline data fetching and caching with SWR, Axios, GraphQL, or RESTful APIs, ensuring that users always interact with fresh, reliable data. By thoughtfully implementing pagination, caching strategies, and optimistic UI updates, I deliver applications that feel responsive and alive, even under heavy load. This careful approach to state and data handling ensures that as your product evolves, your front-end remains stable, maintainable, and efficient.

React Native & Cross-Platform Excellence

Extending beyond the browser, I leverage React Native to build mobile apps that combine native performance with the flexibility of JavaScript. Integrations with native modules, device APIs, and platform-specific optimizations ensure a consistent, high-quality user experience across iOS and Android. By sharing logic and components between web and mobile, I accelerate development cycles and maintain a unified brand experience. Rigorous testing using Jest and React Native Testing Library ensures that every feature works as intended—no surprises at launch.

Google Analytics training for companies

It doesn’t matter if you’re small e-shop or huge corporate. The data that’ll help you find deficiences or find opportunities is extremely valuable. Unfortunately it’s not enough to “have” it – it’s important to know what to do with it.

That’s the reason why one training is much better than tens of hours staring into Google Analytics interface. You’ll learn how to find and leverage the data you have.

Google Analytics training for companies

At first we'll align ourselves on the starting point - we'll find out what you already know, what are your business pillars and what do you want to learn.

Google Analytics training for companies

Complying with principle: „Business first, data second“ is the ultimate goal during trainings. The goal is to get as quick as possible to business valuable information that are in every Google Analytics account. Agenda and difficulty of training always depends on audience knowledge – we can discuss absolute basics or advanced attribution models too. What do I lecture the most?

  • What is Google analytics measurement based on? Who is user, session and interaction?

  • How the data is sent into Google Analytics and how to bend it to find out the most you need about your customers?

  • What traffic sources do we have and where do your highly converting customers come from?

  • How to set-up Google Analytics account, run the measurement and orient in interface?

  • How to filter only the information we need to know and how to understand the metrics we’re looking at?

  • We’ll show the use cases of how to work with UTM parameters, which help you to tag and evaluate the success of your online campaigns.

  • How to measure relevance and content business impact on your website: How do your landing pages or blogposts work?

  • How to measure impact of all your online activities and based on them how to set-up a marketing mix?

  • Where do you lose your potential customers? What are you weak sides of your website and how much money do you lose?

  • How does your buying process work and how much extra revenue you can get?

  • How to set-up enhanced e-commerce modul for e-shops, to find out which products are bestsellers and to know the full path from the first product impression on category list to refunds?

And there’s much more – it’s always possible to design the training exactly for your needs, to leverage the maximum for your business.
