About Me

I'm a Mobile Application Developer worked for Evatoz Solutions Pvt. Ltd. in Noida, NCR, specializing in building high-performance cross-platform mobile applications.

My expertise lies in Kotlin Multiplatform (KMP) and Compose Multiplatform (CMP), where I've successfully achieved ~85% code sharing between Android and iOS platforms. I focus on creating efficient, scalable solutions using MVVM architecture, Coroutines, Firebase, REST APIs, BLE, and clean code practices.

I'm actively seeking contract-based opportunities and freelance projects where I can deliver impactful mobile solutions. I'm also open for full-time positions that offer challenging projects and growth opportunities. Currently spearheading the migration of EVA2Z Connect to CMP architecture, and have successfully built production-ready applications including an AI-powered attendance system with ML Kit achieving 99.65% accuracy, deployed on Google Play Store.
