Real-Time Pricing Engine

Distributed Systems

Distributed event-driven pricing engine designed to deliver sub-100ms p99 latency while processing 50K+ requests per hour. Leveraged Kafka for high-throughput messaging, Redis caching for faster rule evaluation, and Oracle optimizations to reduce computation costs by 60%, achieving 99.95% availability on Docker deployments.

Airline Offer & Order Platform

Microservices

A scalable microservices-based platform was designed and developed to modernize airline retailing, covering the entire flow from offers and pricing to bookings and order fulfillment. Using Event Sourcing and CQRS patterns, complex booking workflows were streamlined while ensuring reliability, fault tolerance, and auditability. The platform now powers modern retailing for global airlines, handling over 10 million transactions per month with 99.9% availability and delivering faster, more efficient processing at scale.
