At Consensys — MetaMask, I architected a shared security-alerts service that checks transactions and signatures across Extension and Mobile, with a WASM/PPOM integration and alert UI for phishing, drainers, and malicious approvals.
I planned and led the move of Extension confirmation logic into a client-agnostic Core controller serving both clients. This eliminated duplicate feature development and halved maintenance per confirmation feature.
I led an investigation that traced slower confirmation loads to legacy code paths; removing more than 15,000 lines made the screen load about 27% faster. I also led gasless transactions (EIP-7702) end to end and architected intent-based batching (EIP-5792) in Core.
Before MetaMask, I shipped backend services at Consensys for Codefi and contributed consensus and client code to Hyperledger Besu. Earlier at INDRA — TELEFÓNICA, I led Agile teams delivering Java tools, introduced unit testing and CI, and supported production systems.
