About Jhon Prieto

I am a software developer with over 9 years of experience in mobile applications, biometric SDKs, and digital identity solutions. Experienced in working across international and multicultural environments, I have collaborated with teams from France, Poland and Latin America on the development of biometric and digital identity solutions. This has strengthened my communication skills, adaptability, critical thinking, and ability to work effectively in distributed teams. Strong problem-solving skills with a proven track record of formulating effective technical strategies and driving innovation. Excellent communicator and collaborator, adept at working in multicultural, distributed, and international teams. I have led and implemented key projects for governments in Latin America, such as Colombia’s Digital ID and Chile’s Digital Identification, including facial capture, fingerprint authentication, SmartCard integration, and image processing in formats like WSQ, JPEG, and RAW. My core expertise includes development and maintenance of iOS mobile applications using Swift, SwiftUI, UIKit, and Combine, applying clean architecture principles to maximize scalability and maintainability. Defined and executed quality assurance strategies including static code analysis with SonarQube, automated testing on device farms (Firebase Test Lab), and continuous deployment using Jenkins and Fastlane, optimizing delivery times and reducing production errors. Fully automated CI/CD pipelines for iOS apps, including provisioning profile validation, automatic signing, and App Store Connect publishing, guaranteeing repeatable and reliable workflows. Clean architecture (MVVM, hexagonal), cross-platform development (Android, iOS, C++, Windows, macOS), and DevOps practices (Fastlane, Jenkins, Docker). Participated in code reviews, debugging, and testing to ensure app quality and performance on multiple devices and OS versions. I have also built logistics, RFID, and mobility solutions from scratch, including backend development with C#, ASP.NET, and SQL Server integrating hardware and software solutions.
