PROFILE
Angelo-farruggia
Worked extensively on the UnionInternationalCheminsdeFer/OSDM repository, delivering and refining API specifications to support cross-border rail data, booking workflows, and payment integrations. Focused on API design and backend development, introduced features such as border point indicators, wallet-based payment options, and unified date-time formats, all implemented using YAML and OpenAPI Specification. Addressed schema consistency and data modeling challenges by standardizing enumerations, clarifying booking policies, and aligning versioning across releases. Prioritized downstream reliability and integration ease by correcting duration formats and removing obsolete specifications, ensuring that API consumers benefit from clear contracts, robust validation, and streamlined onboarding for evolving business requirements.

Mar 1, 2026For 2026-03, delivered a core API consistency improvement in UnionInternationalCheminsdeFer/OSDM: Unified Date-Time Format across API Specifications, standardizing all date-time values to a consistent ISO 8601 'date-time' format to improve client validation and interoperability. No major bugs fixed this month; minor issues identified during alignment were addressed as part of the refactor. Overall impact: increased API reliability for downstream clients, reduced integration friction, and established a solid baseline for future cross-specification standardization. Technologies/skills demonstrated include API specification alignment, data format standardization, version-controlled change tracing, and cross-team collaboration.
