Nikola G.

I keep native Android and iOS apps live and earning: OS and target-API updates, SDK and library migrations, App Store and Google Play releases, and AdMob monetization. What clients hire me for: • Updating existing apps – new Android and iOS versions, Google Play target-API requirements, replacing outdated libraries. Clients rehire me for their next round of updates. • Ad monetization – I implemented AdMob, Yandex and LevelPlay ads across 100+ apps for Net Focus Universal, and I run AdMob in my own published apps. • Integrations – WhatsApp and Viber APIs, chat SDKs on Android and iOS, Firebase push notifications and deep links, REST APIs. • Porting – converting iOS apps to Android with a matching UI. • MVPs from idea to the stores – Figma to code, release, and the first updates after launch. I've also built streaming apps for Android phones, Android TV and Fire TV, and AI features with the OpenAI, Claude and Gemini APIs. Stack: Kotlin, Jetpack Compose, Java, Swift, SwiftUI, Firebase (Auth, Firestore, Cloud Functions), REST APIs, Clean Architecture, MVVM. I use AI tools to work faster, and every change is reviewed and tested before it ships. You get full source code and IP, clear communication in English, and Slack or Jira if your team uses them. Send me your app and what's blocking you, and I'll tell you what it takes.
