PROFILE
Alexis Schlomer
Worked on the cmu-db/optd repository, building foundational elements of the High-Level Intermediate Representation (HIR) type system, including primitives, arrays, closures, and user-defined algebraic data types. Established a registry for type relationships and subtyping, and extended the parser to support new closure syntax and Universe types using Rust. Improved CI stability by addressing code formatting and import order, ensuring reliable builds. Later, delivered comprehensive documentation for the OPTD domain-specific language, creating a tutorial that covers syntax, type system, and transformation rules. Maintained documentation with concise, testable examples, streamlining onboarding and aligning resources with current DSL functionality and database internals.
