I run infrastructure that secures >$100B in decentralized markets. As a Blockchain Systems Administrator, my focus is uptime, cost efficiency, and reliable delivery at scale. From smart contract deployments to Chainlink oracle operations and DON lifecycle management, I make failure invisible and reliability the default.

• Deployed hundreds of smart contracts to mainnet/testnet environments with zero critical incidents
• Maintained blockchain nodes across EVM and non-EVM chains with >99.99% uptime
• Coordinated phased rollouts across distributed infra to ensure smooth upgrades with zero downtime
• Owned the Chainlink Core release process from cut to GA rollout, ensuring clean and predictable upgrades
• Drove cost-optimization efforts including log filtering and node decommissioning, saving thousands per month
• Managed end-to-end Chainlink oracle configuration, tuning, and upgrade cycles
• Contributed to decentralized governance and oracle operations securing >$100B in value
