Roy Melgar

I've built and maintained mobile applications for Keedian, Nivelnet, QSM Solutions, and Sisegusa, delivering Flutter, Ionic, and native iOS products across SaaS, ride-sharing, property management, and wholesale operations.

At Keedian, I led an enterprise SaaS migration from Ionic v3 to Flutter while maintaining and redeploying the legacy iOS application. I also resolved battery-drain issues, introduced component-based architecture, supported BFF integration, and remediated audit-identified vulnerabilities through secure storage, code obfuscation, and root detection.

At Nivelnet, I assessed externally delivered iOS and Android code, established Scrum practices, and stabilized native Objective-C passenger and driver apps. At QSM Solutions, I migrated a property-management app from Ionic v1 to Ionic v3, managed App Store and Google Play releases, and onboarded two engineers.

I'm comfortable owning architecture, deployment, security, and delivery workflows, including SAP ERP synchronization, OTA updates, payment gateways, QR access control, and real-time alerts. I work effectively in Agile teams and bring hands-on experience with Flutter, Ionic, Angular, native iOS, and mobile release pipelines.
