Software Engineer and Cybersecurity Enthusiast

👋 Hi, I’m Alief!

I’m an Software Engineer with over 3 years of experience in building high-quality mobile applications using Kotlin and Java.
I have worked on apps ranging from startups to enterprise-level solutions, including:

  • Bumpp – A social networking app with 5K+ users
  • Livin’ by Mandiri – A banking app with 10M+ users
  • Moka POS – A widely-used POS system with 500K+ users

Beyond Android development, I’m also exploring cybersecurity, focusing on Android app penetration testing and bug bounty hunting.
