PROFILE
Angelo-farruggia
Angelo Farruggia enhanced the UnionInternationalCheminsdeFer/OSDM repository by delivering targeted API and schema improvements focused on cross-border travel analytics, data quality, and contract clarity. He introduced and refined the isBorderPoint indicator in trip leg and stop data, enabling precise border tracking and compliance reporting. Using YAML and OpenAPI, Angelo managed schema versioning, expanded extensible enums for transportation code lists, and ensured backward compatibility across releases. He addressed API contract correctness by clarifying booking deletion policies and standardizing duration formats to ISO 8601. His work demonstrated depth in API design, data modeling, and specification governance, supporting robust partner integrations.

Aug 1, 2025Month: 2025-08 Overview: Delivered a targeted OSDM schema enhancement to expand extensible enums for transportation code lists across OSDM, aligning the data model with the latest code catalog to improve data completeness, flexibility, and interoperability for transport services. Key developments: - Feature delivered: OSDM Schema Enhancement - Expand Extensible Enums for Transportation Code Lists. Expanded extensible enum values across OSDM schemas to reflect the latest catalog of transport code lists, enabling more robust representation of transport services. - Implementation details: Repository UnionInternationalCheminsdeFer/OSDM updated; commits include 7a52577a3916a91f0f39f39bc3f874c0f6a0a5b7 implementing enum additions for v3.4 and v3.5. Impact: - Business value: Improved data completeness and flexibility, smoother partner integrations, and more reliable downstream validation and analytics. - Technical impact: Backward-compatible schema extension (v3.4/v3.5); reduces future mapping effort and supports catalog expansions. Technologies/skills demonstrated: - Data modeling with extensible enums, schema versioning (v3.4/v3.5) - Schema design, code collaboration, git-based traceability - Adherence to specifications and cross-schema applicability

Dec 1, 2024December 2024: Implemented StopPlace Border Point Indicator in the OSDM API for UnionInternationalCheminsdeFer/OSDM, enabling explicit marking of stops that lie on country borders. Removed obsolete 3.4.2 specification to simplify the API surface and align with the current release trajectory. These changes support more accurate cross-border routing and data quality, reduce ambiguity for downstream consumers, and prepare the 3.4.1 line for the upcoming release.

Nov 1, 2024November 2024 (2024-11) focused on data quality, API schema stability, and impact-driven delivery in UnionInternationalCheminsdeFer/OSDM. Delivered a new border point indicator in trip leg stop data to enable precise cross-border analytics and compliance reporting. Upgraded the OSDM API specification to 3.4.2 and removed the isBorderPoint field from StopPlace, accompanied by targeted refinements to enumerations and data structures. These changes improve downstream analytics reliability, support new business requirements, and streamline integrations with partner systems. Demonstrated strong data modeling, API versioning, and change management across the team.
