Senior🎓
Top SchoolCarlos Jim is a Lead Android Engineer based in Madrid with 8 years of hands-on experience building secure, high-performance Android apps and libraries for banks, telecoms and payment platforms. He has led migrations to Kotlin and Jetpack Compose, implemented VIPER architectures, and developed security-focused SDKs for contextual authentication and secure communication. His background spans full-stack and embedded systems work—from biometric SDKs and multimedia playback with IPC-MQTT to backend integrations—giving him a practical cross-domain view of product constraints. At VASS he moved projects forward as both a technical lead and a pragmatic bug-slayer, improving real-time data modules and overall performance. He combines academic research experience in biometrics with industry delivery, which helps him translate novel techniques into production-ready solutions. Colleagues describe him as quality-obsessed and focused on clean code and disruptive, useful technology rather than bells and whistles.
