PROFILE
Thomasporter522
Thomas Porter contributed to the hazelgrove/hazel repository by overhauling the Gradescope grading system, migrating from a Perl-based workflow to a Python-driven grader and Hazel-based automation pipeline. He implemented a single-submission grading workflow, updated command interfaces, and removed legacy batch autograder files to streamline grading operations. Thomas also enhanced the type system’s soundness by refining the join operation for universal quantification in OCaml, ensuring robust type variable management. Additionally, he introduced targeted logging instrumentation in the History component to improve traceability and auditability. His work demonstrated depth in backend development, automation, debugging, and type systems using Python and OCaml.
