I specialize in Android Reverse Engineering, Backend Development, Python automation, and application security. I build secure software, analyze Android applications, and create scalable backend architectures.
Whoami, essentially.
I specialize in Cyber Security Research, Reverse Engineering, Android Application Development, Backend Systems, and Python Automation.
I enjoy breaking complex systems apart to understand exactly how they tick, then applying that mindset in reverse — building applications and infrastructure that are secure, scalable, and built on modern tooling from day one.
Whether it's disassembling an APK, hardening a REST API, or automating a tedious OSINT workflow, my process stays the same: understand the system completely before you trust it.
Technical arsenal.
Tools and technologies I rely on across security research, mobile development, and backend engineering.

Selected builds.
A mix of security tooling, Android research utilities, and backend systems — each built end to end.
Credentials & ranges.
Formal certifications and hands-on practical ranges — placeholders shown where in progress.
Numbers that add up.
Notes from the terminal.
Write-ups and breakdowns across security research and backend engineering.
Let's build something secure.
Open to research collabs, freelance builds & full-time roles.
