About Me
About Me
Flutter Developer
I build mobile applications that don’t just work, they scale. With over 2 years of experience , I specialize in transforming complex business requirements into high-performance Flutter applications for Android and iOS. Currently at SISMATIX Information Technology, I am spearheading the conversion of a full ERP system into a modular Flutter ecosystem. My focus is on Performance Engineering, where I’ve successfully reduced release cycles by 40% using automated CI/CD pipelines and improved data load times by 35% through optimized caching and pagination strategies. Beyond coding, I am passionate about community growth. As a Flutter Instructor for GDSC, I have mentored over 100 students, helping them master the Dart programming language and Flutter framework. Looking for a developer who prioritizes clean code, scalability, and best performance? Let’s connect.
