Authored core protocol code including margin engine, upgrade scripts and migration tooling

Implemented the core smart contract modules that powered lending, margin positions and liquidation routines used by the bZx protocol and later the Ooki deployment. Work included authoring the margin engine, configuring collateralization ratios, writing upgradeable proxy patterns and producing migration scripts that moved state between contract versions. Those concrete code contributions determined precise on‑chain settlement rules, fee flows and interaction interfaces that integrators and front ends relied on. Led or coordinated multiple code releases and hotfixes, validating patches and rollback plans during and after security incidents. Delivered versioned contract artifacts and deployment tooling that controlled token minting/burning hooks and governance integration points for OOKI, so each release changed how the token interacted with staking, fee sharing and treasury functions. The technical ownership of these modules meant that design tradeoffs in code had direct measurable effects on market liquidity and risk exposure for OOKI holders. Engaged with auditors and community developers to specify fixes and mitigations to exploit vectors, producing documented pull requests and release notes used by node operators and integrators. The hands‑on engineering decisions and release management practices shaped both the operational resilience of the protocol and the expectations of counterparties and liquidity providers interacting with the OOKI token.
