Ragavarthini Dhanaraj

I’m a Senior iOS Engineer with 7 years of experience building robust, user-centric iOS solutions at Oviva in Berlin. I’ve authored specialized AI skill files that define core architecture and coding patterns, and I’m focused on keeping generated code aligned with project standards while minimizing hallucinations through context-window discipline.

I’ve developed and maintained an Oviva Direct iOS application for iOS 18+ with a strong security and privacy posture for a medical device, including securing a permanent BfArM directory listing for insurance reimbursement. I lead features end-to-end—from discovery to deployment—refactor legacy systems for stability, integrate design systems to improve cross-team velocity, and resolve complex memory leaks and retain cycles to reduce crash rates. I also enforce code quality by embedding SonarQube and SwiftLint static analysis into GitHub Actions CI/CD pipelines, and I’ve implemented REST API integration with Core Data local caching alongside HealthKit metrics synchronization (blood glucose and blood pressure).
