Led the technical implementation of the core lending protocol, writing and deploying the smart contracts that handled deposits, borrows, collateral management, and liquidation mechanics. Decisions made in contract architecture defined token flow, collateral valuation hooks and the way FOR was used for governance and fee capture. Defined and tuned the protocol's interest-rate model, reserve factor mechanics and liquidation thresholds used on-chain; these technical parameters were implemented in on-chain code and directly affected utilization, APY for suppliers and the cost of borrowing in FOR-denominated markets. Engineering choices included on-chain oracle integration points and gas-optimization trade-offs that shaped user experience and composability. Orchestrated security reviews and audits with external firms, processed audit recommendations into contract patches, and executed on-chain migrations including multisig-controlled upgrades and governance proposals. The applied fixes and upgrade paths materially reduced exploit surface and influenced market confidence in FOR and ForTube markets. Built cross-chain deployment tooling and managed the porting of contract sets to lower-fee environments, coordinating state migrations and liquidity bridge configurations that altered where FOR circulation concentrated and how easily users accessed lending markets.
