What I'm looking for

I seek roles building scalable, secure cross-platform mobile apps where I can improve performance, apply security best practices, and grow in cloud-integrated mobile engineering.

I am a Mobile Application Developer with 5+ years of experience designing, building, and optimizing cross-platform and native mobile applications. I have independently published apps with 5,000+ combined downloads, improved app crash rates by 30%, and enhanced e-commerce checkout speed by 20% through performance tuning and robust engineering practices.

I combine hands-on mobile engineering (Flutter/Dart, Android SDK, Node.js, MongoDB) with security and cloud knowledge, having worked on enterprise-grade projects, SOC simulations, and NIST cybersecurity assessments. I prioritize secure authentication, scalable architectures, and user-centered design to deliver reliable, high-performing mobile solutions.
