• ◦ Lazy Loaded Search: Implemented lazy-loading search architecture with Redis distributed locks, ETag-based caching, and async polling across multiple flight suppliers. Built timeout management, cache bypass strategies for partial results, and polling optimization using load testing. Achieved 60% search latency reduction (8s→3s).
• ◦ High-Concurrency Microservices Optimization: Implemented non-blocking reactive programming using Spring WebFlux across repository layer, eliminating blocking I/O bottlenecks to third-party APIs. Achieved 50% CPU/memory reduction, 60% infrastructure cost savings by downsizing from 50 to 20 pods, 3x better resource utilization, and sustained 70+ RPS peak loads with consistent latency serving 2M+ daily flight search requests.
• ◦ Spring Boot Migration: Led Spring Boot 2.x to 3.x migration across 8+ microservices and migrating from Tomcat to Netty server architecture. Achieved 40% application startup time reduction, and enhanced performance for high-concurrency.
• ◦ JWT Authentication & Token Management System: Designed and implemented feature-flagged JWT refresh token system extending guest session duration 4x (15→60 min). Built 10-minute idle detection with session timeout popups.
• ◦ Ancillary Service Integration: Implemented backend APIs for ”Select Your Drink” feature with dynamic pricing calculations and meal add-on service integration. Built fare summary logic and streamlined backend operations to reduce code duplication.
