PROFILE
Félix Girard
Felix Girard contributed to the iTwin/bis-schemas repository by designing and evolving complex civil engineering data models, focusing on schema development for features such as parcel management, pedestrian infrastructure, and parking layouts. He applied skills in data modeling, schema design, and release management to deliver robust, versioned schemas that improved interoperability and data quality across OpenSite and CivilPhysical modules. Using technologies like XML, SQL, and C#, Felix implemented schema extensions, property deprecations, and naming consistency updates, ensuring traceable, governance-ready releases. His work addressed real-world requirements for urban planning and civil engineering, resulting in maintainable, future-proof backend data contracts.
