Who I am
I'm the Chief Operating Officer of Endaoment, where I built the operational framework for a pioneering onchain 501(c)(3): GCP TypeScript cloud functions, multi-chain smart contract automation, and the compliance procedures underpinning over $150M in audited nonprofit impact. I own the core API alongside the operations stack.
Before Endaoment I spent five years at Morgan Stanley in Wealth Management Finance, running CCAR balance-sheet consolidations during the E*TRADE acquisition, and administering a $1B non-comp expense budget.
My work sits at the intersection of operations, finance, and engineering: turning fragile manual processes into robust, autonomous, observable systems.
What I'm working on
- Running the Endaoment operations and backend platforms: 70+ production cloud functions, 50+ shared TypeScript libraries, and one type-check gate across 150+ projects.
- Building the payout orchestrator: proposer, bank funder, and onchain registrar, with per-chain Tenderly bundle simulation gating every batch before it moves money.
- Codifying Endaoment's agentic development methodology: layered context rules, scoped skills, automated validation gates and human guides.
- Maintaining validators.endaoment.org, the open-source Ethereum validator operations guide.
