Actions
As a Senior Android Engineer at Delivery Hero, I am responsible for improving the performance and quality of the Android app for one of the world's leading online food delivery platforms. I have more than 8+ years of experience in developing Android applications, using Java and other technologies. I am skilled in app performance optimization, user interface design, testing, debugging, and troubleshooting. I am also eager to learn new skills and technologies, and to collaborate with other talented and innovative engineers.

From Perceived Smoothness to Measured Performance: Metrics That Actually Matter in Android Apps
What makes an app feel fast — and how do we actually measure it?
In this talk, I’ll walk through the key performance metrics every Android developer should monitor, from app startup to screen responsiveness, image loading, memory usage, and more.
You’ll learn how to define measurement boundaries, distinguish cold vs warm starts, catch slow frames (even on 120Hz devices), and set up practical observability strategies that scale with your codebase.
Whether you're shipping Compose or Fragments, this talk will help you move from gut feelings to measurable UX quality — with real-world examples and tools like Firebase, Macrobenchmark, Perfetto, and custom analytics.
Size does matter!(App size control automation)
A presentation on how the application size metric in general affects the business and the application itself. How to avoid regression at the development stage (before release) and how to automate it on CI. The report is intended more for the platform (infrastructure) team, it will also be useful for small teams for future development. Technologies: Git, Diffuse tool (by Jake Wharton) - for comparing two APKs and receiving a detailed report, Spotify Ruler plugin - for detailed analysis of the APK size by module, bundletool - for generating APKs from the app bundle
One Tracker to Rule Them All: App & Screen Metrics for Firebase, Sentry & More
Most Android developers rely on out-of-the-box tools like Firebase Performance or Sentry — but what if you want full control over what you measure and where you send it?
In this talk, I’ll show you how to build a lightweight performance tracking library that can:
Track custom app and screen-level metrics (e.g. startup, navigation, image loading)
Start and stop traces with clear lifecycle hooks
Report metrics to multiple destinations — Firebase Performance, Sentry, or your own SDK
We’ll cover:
How to define flexible PerformanceTrace objects
Where to hook them in the Android lifecycle (Activity, Fragment, Compose)
How to route data to third-party tools using clean abstraction layers
Whether you're working in a startup or a large app team, this approach gives you full observability with minimal overhead. You’ll walk away with code samples, architectural patterns, and a reusable tracker you can plug into your app today.
