Tom Houlé is a product-minded software engineer and empathetic team lead with a decade of experience building high-performance backends, schema tooling, and database-focused systems from Berlin. A long-time Rust advocate, he was an early Rust hire at Prisma where he led the Schema team, became the top contributor to prisma-engines, and drove migrations, performance and WebAssembly efforts that improved serverless cold starts and connection management. At Grafbase he designed a Rust-based GraphQL Federation Gateway and the first Rust implementation of federated GraphQL composition, and he speaks publicly on schema and GraphQL topics. He blends deep interests in database internals, formal methods and systems engineering with hands-on debugging and profiling expertise, and has a history of shipping pragmatic abstractions and customer-facing enterprise solutions. Notably, his open-source work includes significant contributions to widely used projects like Prisma and graphql-client, reflecting a focus on correctness and typed APIs.
