PROFILE

Mark Percival

Over six months, MDP enhanced the cline/cline and menloresearch/JanCode repositories by building robust CI/CD pipelines, automating release workflows, and standardizing contribution processes. MDP implemented automated code quality checks using ESLint and Prettier, upgraded testing infrastructure with chai/mocha and ts-node, and improved mention parsing reliability through refined regex. In JanCode, MDP clarified Git LFS requirements and enforced consistent code formatting with Prettier. Across both projects, MDP focused on repository hygiene by removing outdated documentation and unused workflows, streamlining onboarding and maintenance. The work demonstrated strong proficiency in JavaScript, TypeScript, and GitHub Actions, resulting in more maintainable, reliable codebases.
