Kotlin Multiplatform & Android Developer | Jetpack Compose

I help turn ideas into modern Android and Kotlin Multiplatform apps that are clean, scalable, and ready for real users. My core focus is Kotlin, Jetpack Compose, and Kotlin Multiplatform. I contribute to both new apps and established codebases, from feature development and API integration to architecture improvements and release support. The result is software that is easier to extend, easier to maintain, and better prepared for real-world use. I can help with: · Android development with Kotlin and Jetpack Compose · Kotlin Multiplatform apps with shared business logic across platforms · Feature development for new and existing mobile apps · Full-stack Kotlin development with Ktor, including backend services, REST APIs, and WebSockets · Data-intensive app features, persistence, synchronization, and connected client-server workflows · Maps, geolocation, camera, photo, and media-related functionality · Refactoring, architecture improvements, and modernization of existing codebases · AI-assisted development workflows to speed up implementation, debugging, and iteration How I work: · Clean architecture and maintainable code · Clear communication and reliable execution · Comfort working with both new builds and existing codebases · Practical decisions that support long-term product health · Attention to product details, not just raw implementation
