Over nine months, Mihai Plesa enhanced build reliability, security, and governance across Brave’s core repositories, including brave-core, brave-browser, and brave-intl/bat-go. He implemented automated dependency management using tools like Renovate and Dependabot, modernized CI/CD pipelines, and introduced CODEOWNERS files to clarify code review responsibilities. Working primarily with JavaScript, TypeScript, and Go, Mihai streamlined build scripts for Node.js v24 compatibility and synchronized lockfiles to ensure reproducible builds. His work addressed issues such as flaky browser tests and dependency drift, resulting in more stable deployments and maintainable workflows. The depth of his contributions improved both developer experience and release quality.

September 2025 monthly summary for brave/leo: Delivered stabilization and consistency improvements by reverting the esbuild version override to restore default, stable build behavior, and implementing cross-repo dependency lockfile synchronization to maintain a single source of truth for package versions. These changes reduce build drift, speed up deployments, and simplify maintenance across environments.

April 2025 monthly summary: Delivered targeted automation and security tooling improvements across Brave core repos to reduce manual toil and improve maintenance speed. Key deliverables include the removal of the CodeQL Code Scanning workflow in brave-core-crx-packager, signaling a shift in the security scanning strategy; and the introduction of automated npm dependency updates via Dependabot at the repository root in brave-core, including PR labeling and optional CI skipping. Additionally, a cleanup of dependabot.yml was performed to remove an unnecessary commented section, improving maintainability across the automation configuration. Overall, these changes reduce ongoing maintenance effort, improve security posture alignment with updated processes, and strengthen CI/CD automation. Technologies and skills demonstrated include Git/commit hygiene, YAML-based CI/CD configuration, security tooling strategy, and automation of dependency management across multiple repositories.
