A TF-IDF recommender matches candidates while smart contracts anchor every credential immutably on Ethereum.

The Problem

Recruitment data and credentials were easy to tamper with, undermining trust in candidate matching.

What I Engineered

  • Led research as Principal Author on a blockchain-based recruitment system on Ethereum + Solidity (PoS).
  • Implemented a hybrid recommendation engine with TF-IDF vectorization at 85% precision.
  • Anchored credentials on-chain for secure, immutable, tamper-evident trust.
