Milon Das

I’m a Senior Mobile Application and Security Engineer with 8+ years in Android application development, mobile app security, and end-to-end delivery—from architecture to secure implementation and automation. I bring strong expertise in building reliable, maintainable apps using modern Android approaches and clean design patterns like MVC, MVP, and MVVM.

On the engineering side, I work across the full mobile stack: Java, Kotlin, REST APIs, Retrofit/Volley, Coroutines, Room/Firebase, Jetpack Compose, and dependency injection with Hilt. I’ve also delivered CI/CD and automation, managed production readiness through Google Play Console, and used Git/GitHub for version control and team collaboration.

On the security side, I’m focused on secure coding practices aligned with OWASP Mobile Top 10, implementing OAuth 2.0 & PKCE, and protecting data in transit with SSL/TLS certificate pinning and MITM resistance. I also work with Android Keystore and hardware-backed key management, apply end-to-end encryption concepts (AES-256 / RSA), and add runtime protections against tampering using tools and approaches like Frida and Xposed protection strategies.

I’ve led “entire project planning, design and development” on multiple real-world apps, including farmer marketplace workflows, restaurant ordering with payments, school apps with OTP login and daily notice boards, resource/employee tracking, IoT device control, and fully offline ship inspections with Room DB for media storage. I bring that same ownership mindset to every new team—shipping secure, user-ready mobile products.
