Jota E. López Ramírez

Mobile Developer with over 4 years of experience, focused primarily on Flutter for building cross-platform applications. I complement this with Kotlin and Swift when projects require native solutions or integrations. Experience working with REST APIs, geolocation, real-time services and architectures such as Clean Architecture and MVVM. I completed military service, which strengthened my discipline and teamwork.
