PROFILE
[centreon] Mathias Arlaud
Over six months, contributed to the modernization of the centreon/centreon repository by delivering seven new features focused on API development, architecture migration, and code quality. Led the transition to a Symfony-based kernel using PHP and YAML, enabling legacy and modern systems to coexist safely. Integrated API Platform for standardized endpoints, introduced static analysis with PHPStan, and enhanced development workflows with automated tooling. Developed new API endpoints, improved documentation using OpenAPI Specification, and implemented reliability tests to ensure consistent data handling. The work emphasized maintainability, automation, and clear documentation, laying a foundation for scalable integrations and streamlined developer onboarding.

Dec 1, 2025December 2025 Monthly Summary for centreon/centreon: Key deliverables focused on API documentation and usability enhancements. The Centreon API Documentation Enhancement and New Endpoints initiative was completed, consolidating and merging API docs, and introducing new endpoints with improved descriptions to facilitate quicker integrations and developer onboarding. No major bugs fixed this month. If issues arise in the next cycle, we will align on prioritization and resolution SLAs. Impact and business value: The enhanced API documentation reduces onboarding time for partners and customers, accelerates integration timelines, and lowers support overhead by providing clearer guidance and endpoint usage. This strengthens Centreon’s API ecosystem and enables faster time-to-value for integrations. Technologies/skills demonstrated: API documentation and design, documentation-driven development, API endpoint specification, cross-team collaboration and co-authored contributions (commit 533bc08d89d19678417c4abe9e7989d859d5a96e), Git-based traceability, and clear technical writing for maintainability and reuse.

Nov 1, 2025November 2025 monthly summary for centreon/centreon: Focused on improving API data reliability through tests for API Platform collection normalization. Implemented a dedicated reliability test suite to ensure collections are normalized consistently, reducing the risk of inconsistent API responses and data handling errors in client integrations. This work complements existing QA processes and lays groundwork for future normalization fixes.

Sep 1, 2025September 2025: Implemented PHPStan rules to enforce architecture and coding standards in centreon/centreon, including enum naming conventions, finality and test coverage for marked classes, and preventing direct command-bus usage by command handlers to improve maintainability and code quality. This establishes a solid static-analysis baseline for future development and reduces regression risk.

Jun 1, 2025Month: 2025-06. Delivered two major initiatives in centreon/centreon with clear business value: (1) Centreon API Kernel Strangler Migration to a Symfony-based Kernel, enabling a safe, incremental modernization path while preserving legacy functionality; (2) Development Tooling and Static Analysis Integration, introducing Castor, PHP-CS-Fixer, PHPUnit, Deptrac, and PHPStan to improve code quality and developer productivity. No critical user-facing bugs fixed this month; effort focused on architectural uplift and quality gates. Overall impact: reduces migration risk, accelerates future feature delivery, and improves API maintainability and reliability. Technologies/skills demonstrated: Symfony, kernel strangler pattern, PHP tooling ecosystem (Castor, PHP-CS-Fixer, PHPUnit, Deptrac, PHPStan), repository configuration and wrapper/adapter patterns to coexist old and new kernels, and tooling-driven DevEx improvements.
