JustiFire — Device Evidence & Testnet Validation

As a Blockchain Consultant for JustiFire from January through June 2025, I worked on blockchain architecture for device evidence.

My work covered Solidity contracts, device wallets and identifiers, evidence logging and transaction batching. I tested deployment and contract interactions on the Base Sepolia testnet using Remix and Ethers.

This work demonstrates architecture and technical validation. It is a testnet implementation, not a claim of production deployment, an independent security audit or a particular transaction volume.
