Ever wondered how criminals exploit the trust between telecom operators to commit fraud?

I've spent the last 10+ years answering that question—and building solutions.

From designing a <$20 IMSI catcher detector to creating a blockchain oracle that detects cross-operator fraud 12x faster than traditional methods, my mission is clear: make telecommunications infrastructure secure, resilient, and trustworthy.

📡 THE JOURNEY
Started in 2010 researching GSM vulnerabilities. Discovered how easy it was to intercept SMS, clone SIM cards, and track users with basic hardware. Instead of just publishing findings, I built defenses.

Today, as Founder of PT NOZ Berkarya Indonesia, I lead projects that protect millions:
- Emergency BTS systems deployed in national disaster simulations
- SIEM pipelines detecting fraud in real-time across cellular networks
- Web3 Network Behavior Oracle - bringing blockchain trust to telecom

🔬 WHAT MAKES MY WORK UNIQUE
I don't just theorize—I build. Every paper I publish comes with working code github. Every vulnerability I discover includes a detection mechanism. Every framework I design is open-source.

Recent example: Web3 Network Behavior Oracle (NBO): A Decentralized Framework for Privacy-Preserving Telco Security - a complete architecture for cross-operator fraud detection using zero-knowledge proofs. Not just ideas—deployable smart contracts, consensus algorithms, and integration guides.

🎯 AREAS OF IMPACT

• Fraud Prevention: Real-time behavioral analysis across 2G-5G networks
• Emergency Response: Portable communication systems for disaster zones
• Privacy Tech: Zero-knowledge proofs for GDPR-compliant intelligence sharing
• Open Source: Contributing to OpenBTS, Osmocom, Open5GS communities
  
  🏆 RECOGNITION
• 5+ publications with Infosec Institute
• Regular speaker at IDSECCONF (Indonesia's premier security conference)
• GitHub projects used by researchers and operators globally
• Pioneered NFC security research in Indonesia (IDSECCONF 2014)
  
  💭 PHILOSOPHY
  "The best contributions aren't the ones we build alone, but the ideas we release into the world for others to amplify, iterate, and improve."
  
  That's why I collaborate with AI systems ChatGPT, DeepSeek to push boundaries beyond individual capacity. The Web3 NBO whitepaper? Born from philosophical discussions about collective intelligence.
  
  🌏 COMMITTED TO SDG 9
  Building resilient digital infrastructure isn't just my job—it's my contribution to sustainable development.
