Saga Dasgupta contributed to Shopify’s function infrastructure by upgrading the Javy plugin engine in the function-runner repository, leveraging CDN integration and WebAssembly to improve execution performance and reliability. In the shopify-function-wasm-api and cli repositories, Saga stabilized the Function API surface, aligning header, WAT, and Rust module boundaries, and enhanced documentation and test coverage to ensure consistency across the stack. Saga also improved build tooling and dependency management using Rust and C, and introduced granular logging for function executions in Shopify/cli with TypeScript. The work demonstrated depth in backend development, API design, and observability, supporting maintainability and operational excellence.
