Secure Financial Systems

Wallet, identity, signing, and smart-contract work shaped by security reviews and careful release planning.

  • Flutter
  • Solidity
  • Hedera

What I worked on

  • Integrated wallet, escrow, identity, and signing flows across mobile, cloud functions, and smart contracts.
  • Worked with Hedera and EVM-compatible networks, encrypted keys, NFC documents, biometrics, and cryptographic proofs.
  • Reviewed messaging, mobile startup, and smart-contract code for security and performance issues, then documented fixes.
