Freelancer profile translated to English.

Description

Freelance mobile developer, 10 years of experience in native Android (Kotlin/Java), Kotlin Multiplatform (KMP) and Flutter.

I have delivered and evolved high-traffic consumer applications and business apps in demanding sectors (health, payment, BLE, media), with a strong focus on architecture (Clean Architecture, MVVM), testing, and quality.

I handle both cross-platform migrations (native to KMP or Flutter) and end-to-end app development, autonomously. I work fully remotely, on a fixed-price or time-and-materials basis, focusing on deliverables and results.

Available immediately.
