Kartik Arora — Senior Software Engineer

I’m a Senior Software Development Engineer in the Order Management Service (OMS) team at Expedia Group, building the distributed orchestration layer that powers booking and post-booking workflows across multiple lines of business. My work focuses on designing session-based, preview-then-execute workflow systems that ensure consistency, recoverability, and reliability across distributed services integrating supply and payment systems. Key contributions include: • Designing and implementing session-based cancellation workflows replacing legacy stateless architectures • Authoring HLD/LLD and driving cross-team architectural alignment across orchestration and domain services • Building centralized refund calculation services (gRPC, Java) to standardize multi-payment refund distribution • Improving p99.9 SLAs and reducing error rates through performance optimization and system redesign • Designing order modification architecture (Lodging Combo Change) with production-ready APIs, payment wiring, and execution flows Recently demonstrated AI-augmented architecture design workflows, compressing multi-week discovery and design cycles into days using enterprise-integrated LLM tooling while maintaining code-backed traceability. I’m deeply interested in distributed systems, workflow orchestration, consistency models, and building scalable backend platforms.
