• Facilitated technical response teams (TRTs) while on-call to assess production issues for impact to customers, restore service, communicate to internal and external stakeholders, and analyze the root cause

• Conducted greenfield research for teamwide migration from Datadog to Grafana for monitoring

Highlighted clients/contributions include:

• Lexidus Holdings (quant trading firm): Increased system uptime by >2% by automating processes that required 30 min. of human involvement daily to reboot programs at midnight. Material positive impact on profits given trading volume gained during the additional uptime. (Bash scripting, Linux, Java, Solidity, PostgreSQL, Geth)

• Webacy (blockchain security startup): Built in-house tooling to simulate transactions on EVM (Ethereum Virtual Machine) blockchains against the latest state of the blockchain, saving thousands in annual third-party software costs. (TypeScript, Solidity, Firebase)

• Internet Money (crypto wallet app): Wrote audited smart contract code that has been trusted with >$117M user swap volume on decentralized exchanges. Built backend functionality to quote the most optimal route for a pair of tokens across multiple on-chain liquidity sources. (TypeScript, Solidity, PostgreSQL)

Additional clients include: CZero / Autaly / Margin, Sperax, Llama, Aave, Bitcoin Market Journal / Media Shower, Jackpot, Bind Markets / Orda, Eddii Health
