* Built and maintained core protocol infrastructure for the Solana lending protocol, including low-level program components such as custom memory allocation systems, rate limiting mechanisms, and critical protocol upgrades. * Integrated and maintained oracle infrastructure used for collateral valuation, risk management, and liquidation logic across the protocol. * Developed cross-program integrations (CPIs) with major Solana DeFi protocols including Kamino Finance, Drift Protocol, and Solend to expand protocol interoperability and capital efficiency. * Contributed to release processes by reviewing large protocol upgrade PRs, auditing changes, and reviewing contributions from open-source developers. * Built and maintained internal developer tooling and CLI utilities to streamline protocol operations, testing, deployment workflows, and engineering productivity.

* Built and maintained core protocol infrastructure for a Solana fixed-rate lending protocol, including zero-copy account layouts, the order-book matching engine for borrower bids against curator-managed lender asks, and the loan state machine. * Integrated and maintained oracle infrastructure across Pyth Network and Switchboard feeds for collateral valuation, match-time LTV enforcement, and liquidation logic, including staleness and confidence interval safeguards aligned with marginfi-v2 risk models. * Developed the cross-program integration (CPI) with marginfi v2 to support the protocol’s variable-rate lending layer, including share-to-asset conversion adapters, projected interest-rate calculations, and fallback liquidity routing for unmatched order-book positions. * Implemented the vault and risk-profile system enabling curators to manage per-asset lender pools with configurable LTV caps, loan duration limits, fee distribution, and bad debt accounting across the full loan lifecycle. * Designed and maintained client integration infrastructure including instruction builders, typed account loaders, on-chain telemetry logging, and native/SBF integration test harnesses to improve protocol reliability and developer experience. * Built and maintained the off-chain backend powering the protocol, including the on-chain indexer that ingests program logs and account state, the API serving the frontend and analytics, and the permissionless cranker / keeper workers that process matched loans, settle matured loans, and trigger liquidations.

* Built and maintained core smart contract infrastructure for a decentralized perpetuals exchange inspired by GMX-style liquidity and risk architecture. * Developed backend keeper systems responsible for order execution, liquidations, funding updates, and automated protocol operations. * Built indexing infrastructure and on-chain event processors to support protocol analytics, position tracking, and frontend integrations. * Integrated oracle and pricing infrastructure used for collateral valuation, funding calculations, and liquidation execution. * Contributed to protocol architecture spanning leverage trading, liquidity management, risk controls, and cross-component backend coordination.
