• Designed a 3-level entity model (Header → Item → SubItem) with strict consistency enforcement across nested data structures
• Integrated 7 OData services (V2 and V4), consolidating responses into a centralized JSONModel to abstract service-layer differences

• Implemented draft state recovery to handle partial failures mid-pipeline without data loss
• Supported 3 operational modes (Create, Copy, Draft Edit) with unified internal state management despite different initialization flows
• Built Excel mass-upload feature with file parsing, row-level validation, and transformation into nested structures aligned with backend schema
• Developed country-specific rule engine for conditional validations, dynamic field control, and compliance-driven UI behavior
• Extended an existing Shipping Instruction SAP Fiori application by implementing new business features and resolving production defects under tight SLA timelines
• Triaged and resolved defects raised by functional consultants, coordinating fixes across UI layer, OData bindings, and backend service contracts
