I reverse-engineer Android applications to understand how real-world APIs behave,
then turn the findings into typed, tested, and documented Python tools.
- 🔬 I focus on Android reverse engineering, mobile API research, and authentication flows.
- 🐍 I build maintainable Python SDKs with type hints, offline tests, and practical documentation.
- 💳 My current research explores Indonesia's e-wallet and QRIS merchant ecosystem.
- 🛡️ I care about responsible research: findings are evidence-based, sensitive data is never published, and unknowns stay clearly marked as
TODO. - 🤝 I'm open to open-source collaboration, security research, and interesting Python projects.
My principle: research, don't guess. Every claim should be traceable to code, a capture, or a reproducible test.
