Building Engaging, High-Performance Android Apps

Delivering User-Centric, Resilient Mobile Experiences with Modern Kotlin & Jetpack

With extensive experience as a Senior Android Engineer, I specialize in crafting dynamic, reliable, and resource-efficient mobile applications that captivate users and support complex business objectives. By leveraging Kotlin, Jetpack components, and MVVM design patterns, I develop maintainable codebases that facilitate rapid iteration and long-term scalability. My approach integrates Compose for intuitive UI development, Retrofit and Coroutines for efficient data fetching, and robust background processing with WorkManager—ensuring every feature performs seamlessly under real-world conditions.

I adhere to Agile methodologies, employ TDD with JUnit and Espresso, and integrate CI/CD pipelines (GitHub Actions, Jenkins) for frequent, stable releases. Whether migrating legacy code to modern architectures, enforcing dependency injection with Hilt, or optimizing network calls with caching and offline-first strategies, I deliver polished, future-ready Android solutions. Let’s work together to transform concepts into immersive, high-quality mobile experiences that delight your users and advance your strategic goals.

How may I help you?

High-Performance Android Development

My Android solutions are built with performance in mind. From leveraging Jetpack Compose to streamline UI creation and enforce Material Design guidelines, to implementing advanced caching strategies and offline synchronization with Room, I ensure consistent performance—even in low-connectivity environments. I routinely profile and optimize code to reduce memory usage, improve render times, and enhance animations. This meticulous attention to detail results in apps that load quickly, run smoothly, and adapt gracefully to various device sizes and capabilities—ultimately boosting user satisfaction and retention.

Scalable Architectures & Modern Tooling

A maintainable, scalable codebase is the backbone of any successful Android app. I champion MVVM, Clean Architecture principles, and dependency injection (Hilt/Dagger) to separate concerns, improve testability, and facilitate ongoing enhancements. By embracing Kotlin coroutines, Flow, and RxJava, I ensure responsive, non-blocking UIs and robust background operations. My use of Gradle, Git/GitHub, and static code analysis tools (Lint, KTLint) guarantees consistent quality across the entire development lifecycle. This focus on architecture and tooling means your Android apps are not just functional—they’re poised for seamless evolution and growth.

Reliable Data & Networking Integrations

I integrate backends and data sources seamlessly into your mobile applications. Using Retrofit, OkHttp, and GraphQL, I handle data fetching, error handling, and rate limiting with precision. Secure RESTful APIs, encrypted local storage, and offline-first strategies ensure data integrity, even in challenging network conditions. By applying best practices in caching, pagination, and resource usage, I create data layers that strike the perfect balance between reliability and efficiency. Your users always interact with fresh, accurate information, delivered at optimal speed.

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

1. What's your level

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.
