Complete redesign of the product catalog indexing process. The legacy system had inefficient processing. A new architecture based on object factories, batch processing, and data streaming was implemented, eliminating bottlenecks in bulk catalog updates.

• Bulk indexing: shifted from product-by-product processing to massive batches, drastically reducing network round-trips and total execution time.
• Proven performance: indexing 1M products cut from ~53 minutes to ~10 minutes, with a sustained throughput of ~1,600 documents/second.

Validates hotel prices served to clients against contracted rates. Compares expected price files with the internal availability API and generates Excel and CSV accuracy reports for auditing. Processing runs as scheduled background jobs to handle large volumes without blocking the system.

• Per-client and per-market accuracy reports available for auditing and continuous monitoring.
• Asynchronous processing of large rate volumes with no impact on system performance.

Automates baggage traceability under the IATA audit framework. Reads the bagtag IDs requested by airlines, queries the BHS system database and reconstructs the full journey of each bag to determine whether the failure is attributable to the handling system or the airline.

• Zero human errors in journey reconstruction, delivering more reliable results.
