Over mij
I’m Shani, an Android & Full-Stack Developer with 4+ years building production-ready apps used by real users. I specialize in Kotlin, Jetpack Compose and scalable backend systems. I’ve independently launched and shipped apps like Private Vault (AES-256-GCM security) and SaaS tools solving real production challenges.
I help with Android development, Spring Boot, MVVM architecture, Supabase, performance tuning, bug fixing, Play Store publishing.
I don’t just write code. I ship products that real users pay for. Clients choose me for clean architecture, reliable delivery, and long-term support.
