Hi there 👋

DeFi Risk & Data Analyst. Previously Data & Finance Officer at Morpho — now building on top of what I learned there.

Background in data engineering. Comfortable across the stack: smart contracts, protocol analytics, on-chain data pipelines.

What I'm building

UMYO — USDC Yield Optimizer on Morpho/Base

A non-custodial ERC-4626 vault that routes USDC into the highest-yielding Morpho market on Base. Owner/keeper separation, pause/emergency-withdraw mechanics, reentrancy protection, and reward claiming built in.

Open source contributions

  • DeFiLlama — protocol adapters and TVL integrations · 3 merged PRs

Background

  • Morpho — worked at the protocol, hands-on with Morpho vaults and yield mechanics as a user and builder
  • Data engineering — on-chain data pipelines, analytics, SQL, protocol metrics
  • Smart contracts — ERC-4626 vaults, access control patterns, testing with Foundry

Stack

EVM · Morpho
Solidity · Foundry
Python · SQL · Apache Suite

Building in public. All feedback welcome.
