Bashar A.

During my tenure at Zendra Health, I was responsible for maintaining and advancing their healthcare mobile ecosystem, leveraging Flutter alongside native Android (Kotlin/Java) and iOS (Swift) to ensure high performance and platform-specific reliability. I successfully integrated legacy native modules into the Flutter codebase, implementing platform channels and refactoring outdated components to create a unified, efficient architecture. In addition, I engineered and maintained backend services using Spring Boot, optimizing API performance, improving security layers, and ensuring seamless interoperability with the mobile applications. A major accomplishment was leading the development and deployment of the Zults application (myrezults.com), delivering a production-grade, scalable healthcare solution adopted in real clinical workflows.
