Software engineer and security researcher · Founder of GreYat Labs · Computer Science @ UNIBEN
I build on-chain systems and take other people's apart. At GreYat Labs I ship end to end across Rust, Solana, Sui and Bitcoin: programs, tooling, autonomous agents and the interfaces on top of them. The other half of my work is independent security review, with every finding written up with a reproduction, an impact assessment and a fix.
- Sonar: live prediction-market signals, now moving on-chain to Solana.
- Bitcoin protocol development: threshold signing, transaction encoding and wallet forensics.
