About

I'm Aleksa, Co-Founder & CTO at Aetherius. We specialize in helping companies and develop and scale iOS and Android apps. Also, we are experts in migrating native iOS and Android apps to Kotlin Multiplatform, helping teams: - Reduce code duplication - Speed up development - Simplify maintenance A few businesses we’ve helped grow through code, architecture design, and strategy: 📍 wheretogo – From idea to execution: we developed an location recommendation platform that helps users discover relevant places based on preferences. With a strong focus on UI/UX and multiplatform support, the product was ready for launch in just under 3 months. 📱 Izbegni Aditive – Over 100,000 downloads in the first year. We helped our client create a mobile app that helps users scan and understand food additives using a smart database and barcode scanner. The app is actively improving public awareness and food transparency in the Balkans. 👷 Znam Majstora – 15.000+ service providers onboarded in the first 6 months. We built a scalable service marketplace platform that connects users with verified craftsmen. From backend architecture to frontend UX, we delivered an end-to-end digital solution tailored for rapid growth. And many more. If you're curious, just reach out 👀 If you're considering KMP for your product or need any help with your iOS and Android app, I’m happy to connect ☕
