About

I’m a results-driven Senior Mobile Application Engineer with over 6.5 years of experience designing, developing, and deploying high-performance mobile apps across cross-platform and native stacks. I’ve led complex enterprise migrations, including moving an eFacility product from Xamarin.Forms to .NET MAUI and upgrading core architecture to .NET 9—improving scalability and system performance by 40% while boosting UI responsiveness by 30%. I architect scalable solutions using Clean Architecture and MVVM, establish automated CI/CD pipelines with GitHub Actions/Jenkins, and drive rigorous code reviews across cross-functional teams to reduce deployment times by 20% and production bugs by 25%. I also prioritize secure authentication, performance optimization, and reliable releases—publishing and maintaining apps on both Google Play Store and Apple App Store with 100% compliance to release guidelines and performance standards.
