👋 Hey there! I'm

Muhammad Alief

Android Developer & Cybersecurity Enthusiast turning complex systems into smooth experiences. I build scalable Android apps with Kotlin & MVVM/Clean Architecture — and occasionally break apps to make them more secure. Currently exploring KMP, automation testing, and Blue Team security to level up both defense and innovation. 🚀

What I Do

I help teams ship better software faster. Whether you need a full-stack developer, API architect, or technical advisor, I bring expertise across the modern web stack.

Android Development

I develop modern Android applications using Kotlin, MVVM, and Clean Architecture. From building new features to refactoring large codebases, I focus on modularity, scalability, and clean code that’s easy to maintain and extend.

App Security & Reverse Engineering

I analyze applications for vulnerabilities, strengthen security, and provide insights from the attacker’s perspective. I've identified real-world issues such as OTP bypass and account takeover attack paths.

Performance & Optimization

Users feel every millisecond. I diagnose and resolve performance bottlenecks in apps — optimizing network requests, memory usage, and rendering to deliver smooth and responsive mobile experiences.

Let's Work Together

Got a project idea? Need help scaling your application? Or just want to chat about code? I'm available for consulting, contract work, and technical advisory roles.
