🚨 Production incident? I fix crypto & backend systems → contact

I build, debug, and stabilize complex distributed systems, crypto infrastructure, privacy-oriented networking, and high-load backend platforms.

Building systems across crypto, privacy networks, distributed backends, and production infrastructure.

My engineering focus:

• Blockchain & crypto infrastructure
• Distributed systems reliability
• Backend architecture and production debugging
• Privacy-oriented networking
• High-load systems
