Real world results
Challenges
This is my first Kotlin Multiplatform app, so a major challenge was setting up the environment and ensuring everything worked as expected on both iOS and Android platforms.
Contribution
MVP for ZnamMajstora was finalized in 6 months, and is in active development phase.
Technology
The app is written completely in Kotlin Multiplatform with SwiftUI for the UI on the iOS side, and Compose for the UI on the Android side.
Business results
ZnamMajstora is now being used by 5000 daily active users across iOS and Android platforms.
Challenges
Performance optimization was the main challenge in iOS app. We implemented custom prefetching logic on top of the Nuke library to ensure a smooth user experience for the home feed.
Contribution
In under 2 months, I migrated the home feed from SwiftUI to UIKit with custom image prefetching, improving performance by 35%.
Technology
The app is built entirely in SwiftUI and fully modularized with SPM. For performance, especially in the image-heavy home feed, we used a UIKit-specific solution with UICollectionView.
Business results
In the first 3 months the WhereToGo iOS app was on the AppStore, it got to 4.8 rating over 129 reviews.
Challenges
Delivering Android for Dopalearn startup in a very short timeline and optimizing iOS application load times.
Contribution
Developed the Dopalearn Android app in under 3 months and optimized iOS performance by removing 500+ re-renders.
Technology
The app was written in Swift and SwiftUI on the iOS side and Compose and Kotlin on the Android side.
Business results
Gained 1,000 new users within just 2 days of launching the Android app, showing strong early growth.
Challenges
MEGA Challenges: Working on both the MEGA iOS and MEGA VPN app, the challenges varied. MEGA iOS focused on scaling features in a 10-year-old mixed codebase, while MEGA VPN centered on SwiftUI and VPN.
Contribution
I migrated MEGA iOS Cloud Drive from Objective-C/UIKit to SwiftUI with another engineer and helped develop MEGA VPN iOS app from scratch to App Store launch.
Technology
The MEGA iOS app is a mix of Objective-C, UIKit, and SwiftUI for new features. The MEGA VPN iOS app is built entirely with Swift and SwiftUI, also supporting macOS Catalyst.
Business results
Migrated Cloud Drive to SwiftUI for 300M MEGA iOS users. MEGA VPN iOS app reached 4.1 rating from 106 reviews in 2 months on the App Store.
Challenges
Two main challenges with Mindguard iOS and Android application were blocking other apps feature, and integrating with AI which can, based on user uploaded PDF, generate a set of questions and answers.
Contribution
App was completely developed from scratch in just 3 months and shipped to AppStore and PlayStore.
Technology
Written completely in SwiftUI and fully modularized with SPM. App blocking feature was implemented using iOS and Android native, while the AI integration was implemented using pdf.ai.
Business results
We were able to achieve a 100% crash free rate among beta testers and early adopters during the testing phase.

Ownership mindset
"Build it like it's your own" is the mindset which I bring to every project I work on. And you'll see the results right away.
Always delivered on time
No more delays and missing deadlines (yes, you read that right). I make sure your users or stakeholders get delivered with the features you want on time.
No hidden costs
It's important for you to plan your costs up-front, and I am aware of that. That's why, when working with me, you will know how much it will something cost you from the beginning.
