During July 2025, Jeriel Verissimo developed Clojure language support for the Automattic/harper repository, expanding the tool’s parsing capabilities to include Clojure code. He implemented end-to-end changes across the parser, build system, and automated tests, updating Cargo.toml dependencies and refining comment parsing logic to handle Clojure’s syntax. Using Rust and leveraging skills in language parsing and CI/CD, Jeriel ensured robust test coverage for new edge cases, reducing integration friction for Clojure users. This work deepened Harper’s applicability for enterprise workflows by enabling first-class Clojure support, reflecting a thorough and systematic approach to language extension and software maintainability.
