PROFILE
Félix Girard
Felix Girard contributed to the iTwin/bis-schemas repository by designing and evolving complex civil engineering data schemas over six months. He delivered features such as new geometric types, parcel management, and polymorphic classification, focusing on improving data modeling and interoperability. Felix applied skills in schema definition, backend development, and release management, using technologies like C#, SQL, and GraphQL. His work included deprecating legacy properties, refining schema relationships, and ensuring robust version control. By emphasizing maintainable schema evolution and precise release cycles, Felix enabled more efficient data entry, consistent downstream integration, and reliable migration paths for clients working with civil infrastructure data.

Jul 1, 2025July 2025 — iTwin/bis-schemas: Delivered three key schema changes and release packaging that improve stability, clarity, and downstream validation. Key features delivered: 1) Release packaging and version bump for ClassificationSystems 01.00.04 (commit be277ccc0bc95627a8a134da5bc90457344acd4c), 2) Schema naming consistency update for sidewalk group reflecting new naming (commit 2459339aab61a0ded6d07a23d4ffda26071aab8f), 3) PadArea parkingAllowed field addition to indicate parking permissions (commit ff9a5e6ac035b4fd8fd59460d5907c7377768ac5). No major bugs fixed this month; focus was on feature-driven schema evolution and release readiness. Impact: enhances client integration reliability, avoids naming drift, and enables parking rules enforcement in downstream systems. Technologies/skills demonstrated: schema evolution, release management, naming conventions, and strong commit-based traceability.
