Building things & breaking them.
Versatile developer who treats security like a craft — building resilient systems by understanding how they fail. From game memory editing at 14 to certified security researcher.
I approach every system with the mindset of both a builder and a breaker — writing clean, maintainable code while constantly questioning how it could fail. Whether it's developing full-stack applications or conducting security research, the goal is always the same: make things work, then make them unbreakable.
“learned reverse engineering before learning clean code.”

My Journey
8+ years from game cheating to software engineering & cybersecurity
Started in 2017 as a curious gamer discovering cheat tools, then progressed through memory editing and APK reverse engineering. By 2019, shifted focus to cybersecurity. Survived the pandemic grind, earned a Cyber Security certification in 2023, pivoted to Software Engineering in 2024, and joined Google Developer & Microsoft Student Ambassador in 2025.
The Curious Gamer
Frustrated with heavy game grinding, started looking for ways to get resources faster. Discovered the world of 'game cheating'.
Frustasi dengan grinding game yang berat, mulai mencari cara untuk mendapatkan resource lebih cepat. Menemukan dunia 'game cheating'.
Cheat Tools Era
Learned and mastered tools like Lucky Patcher and Game Guardian. Became familiar with memory editing and value manipulation.
Mempelajari dan menguasai tools seperti Lucky Patcher dan Game Guardian. Mulai familiar dengan memory editing dan value manipulation.
Beyond The Tools
Not satisfied with existing tools, started learning to edit APK metadata directly. Custom values without external cheat applications.
Tidak puas dengan tools yang ada, mulai belajar edit APK metadata secara langsung. Custom value tanpa perlu aplikasi cheat external.
Discovering 'Hacking'
Got attracted to the hacking world. Learned from various sources, discovered security tools, and found GitHub as a treasure trove of knowledge.
Tertarik dengan dunia hacking. Belajar dari berbagai sumber, mengenal tools security, dan menemukan GitHub sebagai gudang ilmu.
The Pandemic Challenge
COVID-19 hit and made it harder to access learning resources. But this challenge only made me stronger and more persistent.
Pandemi COVID-19 datang dan menyulitkan akses ke resource belajar. Tapi tantangan ini justru membuat saya semakin kuat dan pantang menyerah.
The Long Grind
Long period of deepening cybersecurity knowledge. Learning from practice, experiments, failures, and consistently sharpening skills.
Periode panjang memperdalam ilmu cybersecurity. Belajar dari praktik, eksperimen, kegagalan, dan terus mengasah skill secara konsisten.
Certified Expert
Felt confident enough, took the leap to get certified and successfully earned the Cyber Security certification.
Merasa sudah cukup capable, memberanikan diri mengambil sertifikasi dan berhasil mendapatkan gelar di bidang Cyber Security.
Software Engineering
Got interested in Software Engineering as it aligns well with Cyber Security. Started a new journey as a developer.
Mulai tertarik dengan Software Engineering karena sejalan dengan Cyber Security. Memulai perjalanan baru sebagai developer.
Recognition
Joined Google Developer and Microsoft Student Ambassador. Continuing to learn and grow at the intersection of security and development.
Bergabung dengan Google Developer dan Microsoft Student Ambassador. Terus belajar dan berkembang di persimpangan antara security dan development.
