Senior🎓
Top SchoolAlexandr Tsvetkov is a Senior Android Developer and mobile software architect with 12 years of hands-on experience building secure, high-performance Android and multiplatform applications. He excels both as a solo contributor and as a team lead, having architected complex projects from P2P WebRTC messengers with serverless signaling to modular multi-client banking apps and HIPAA-compliant video systems. His technical depth spans Kotlin/KMP, Jetpack Compose, NDK, Coroutines/Rx, and specialized areas like NFC, BTLE, OpenGL ES, DRM and on-device ML, combined with practical security expertise in reverse engineering and AES/NDK implementations. Alexandr is an active open-source author (notably TAO Bubbles and TAO NFC SDK) and repeatedly modernizes legacy codebases into robust, multi-module architectures. Based in Zaporizhzhia, Ukraine, he often takes short, impact-driven contracts but is now focused on finding a long-term role to shepherd a flagship mobile product through its full lifecycle. An unusual strength: he has repeatedly delivered truly serverless P2P workflows that minimize metadata exposure while enabling rich media and high-speed file transfer.
