PROFILE
Kyriel Abad
Worked on the source-academy/js-slang repository, delivering both foundational language features and targeted maintenance improvements. Built and integrated the CSET machine and a Scheme macro system, refactoring core evaluation logic to support advanced metaprogramming and macro-based abstractions. Emphasized stability by adding comprehensive tests and improving maintainability for future language enhancements. Addressed runtime reliability by correcting the REPL entry point for proper Node.js interpreter usage and streamlined the codebase through removal of unused tracer components. Enhanced contributor workflows by refining the pull request testing checklist. Utilized JavaScript, TypeScript, and skills in compiler design, refactoring, and testing throughout the work.
