PROFILE
Guillaume Mazoyer
Guillaume worked extensively on the opsmill/infrahub repository, building and evolving core backend systems for access control, IP address management, and template-driven configuration. He designed and implemented granular role-based permissions, unified authorization logic across REST and GraphQL, and delivered robust schema validation to ensure data integrity. Using Python, GraphQL, and TypeScript, Guillaume enhanced the IPAM module for accurate capacity planning, introduced transactional safety in object creation, and modernized asynchronous workflows. His work emphasized maintainable code, secure permission boundaries, and reliable migrations, resulting in a platform with improved governance, auditability, and operational safety for complex infrastructure management scenarios.

Oct 1, 2025October 2025 Monthly Summary for opsmill/infrahub: IP Address Management improvements focused on ensuring data integrity and reliable capacity planning. Delivered a fix to cap IP prefix utilization calculations at 100%, preventing values above 100% and ensuring accurate IPAM reporting across dashboards and downstream systems. The correction eliminates reporting anomalies and reduces risk of misallocation in automation workflows. This work was implemented under IFC-1819 with commit b036efbd9b3d3591ef86c246dc9346f93011a048 and references (#7388). Overall impact: more trustworthy IPAM data, improved operator confidence, and smoother capacity planning. Technologies/skills demonstrated: boundary validation, data validation, bug isolation, version control discipline, cross-repo traceability, and adherence to issue-tracking standards.

Jul 1, 2025July 2025 – opsmill/infrahub: IPAM data accuracy gains, mutation namespace restructuring, governance improvements, and async modernization. Highlights include: IPAM Improvements and Availability (GraphQL now returns available prefixes/addresses; fixes for empty-parent subnets; includes prefix length in IP ranges; fixes duplicate member_type arg in prefix pool); Infrahub GraphQL Mutations Namespace Restructuring (new Infrahub namespace for resource mutations and deprecation of legacy mutations); Admin Permissions and Initialization Refactor (new permission to review proposed changes and refactor of default roles, groups, and permissions); Platform API Maintenance: Async Refactor (migrated member.extract operations to async/await to align with SDK changes). Business value: improved data visibility, safer mutation workflows, governance, and maintainability.
