Emily Pillmore is a Senior Engineering Manager specializing in data and tooling with 11 years of experience building production-quality software and leading teams across blockchain, streaming, and finance domains. A long-time functional programming advocate, she cut her teeth in Haskell—serving as CTO and now Board Member of the Haskell Foundation and contributing to flagship projects like Cabal and the Pact smart contract language. She blends hands-on backend work (refactoring Cabal’s source-distribution code and enhancing Pact’s hashing and codegen) with managerial craft, currently overseeing indexers, ETL, and OLAP at Ava Labs. Emily’s background in mathematics and applied category theory informs a rigorous approach to system design and formal verification, while her time at Disney Streaming and financial institutions shows she reliably operates at extreme scale and in regulated environments.
