PROFILE

Alexis King

Over a two-month period, contributed to backend and language infrastructure projects by enhancing database query locking in the slick/slick repository and improving syntax handling in racket/racket. Developed a unified locking API in Scala, adding support for SELECT ... FOR SHARE and refactoring existing mechanisms to strengthen data consistency under concurrent access, with comprehensive test coverage to ensure reliability. In Racket, addressed a critical bug in syntax-local-introduce handling within stream processing, reinforcing robustness through targeted regression tests. Demonstrated expertise in backend development, SQL, functional programming, and test-driven development, delivering maintainable solutions that improved reliability and developer productivity across both repositories.
