Ashriya Infotech • Full time

Jan 2023 - May 2026 • 3 yrs 4 mos

• Built Java and Spring Boot REST services for booking, inventory, availability, and third-party supplier integrations on PRIOTICKET, supporting distributors and OTAs through event-driven and asynchronous workflows. • Integrated suppliers including Viator, Tiqets, Disney, and Galaxy Connect, transforming external APIs into standardized product and booking workflows. • Reduced Viator product-processing time from up to 120 seconds to approximately 5 seconds per product—a 96% improvement — using local processing and asynchronous workflows across approximately 100,000 products. • Implemented Redis-based batch availability caching and Kafka-based asynchronous booking workflows to reduce supplier dependency and handle high-latency APIs. • Built timeout-booking reconciliation with status verification, retries, cancellation, and escalation to prevent duplicate bookings and maintain consistency. • Reduced availability API latency by 98%, from approximately 500 ms to 10 ms, using Fastly caching while sustaining 1,000–2,000 RPS in performance tests.
