The Trade Everything Engine. The Exotic Perps Dex where you can short/long any data stream. - modifications of the core immutable Solidity contracts - building and supporting upgradeable router contract - improving contracts test suit, migrating to Foundry, adding invariant tests - owning protocol's subgraph repository - frontend and SDK modifications (with LLM help) - countless utility scripts (Python, MongoDB, etc.) - EVM, Solidity, Foundry, The Graph Protocol, OpenZeppelin

I was responsible for modifying the Liquity protocol to accommodate multiple assets, governance, and upgradeability, removing the protocol token and staking contract while maintaining system economics, collaborating with Chainlink and Tellor to adjust price feeds, implementing tokenomic upgrades, creating a new codebase for a Proof of Concept (POC) lending protocol, and developing custom hardhat tasks and tests using Chai and Mocha.

I was doing a lot of Ruby/Rails related work before. Mostly backends, API integrations, tests, and docs
