1. Senior Software Development Engineer

   Expedia Group

   Mar 2023 — Present · Seattle, WA, US

   Architected and developed multiple Tier-0 Multi-LOB gRPC Kotlin services to power all Expedia brands content use cases, handling QPS with 99.9% availability. Managed the full SDLC, drafted RFCs, standardized API schemas and patterns across 6+ domain teams to design a scalable, resilient and a high-performance system.• Led the strategic migration of 100+ clients from a legacy Tier-1 monolith by inner-sourcing on the domain services using SPI bridge pattern. Collaborated closely with critical stakeholders (Search/Checkout/Shopping/Offers etc.) to ensure no impact. Achieved $1Min annual cloud cost savings with zero incidents and a 4x increase in Test & Learn (TnL) velocity.• Developed a new Text domain gRPC service utilizing a taxonomy-backed system and on-demand generation. Reduced storage over-head and improved data quality, resulting in a 2x increase in TnL experimentation.• Engineered a Tier-0 identifier mapping service handling 21k QPS for ID translations across multiple critical teams. Owned the full implementation, including cache loaders and Redis/ScyllaDB integration, to guarantee consistent single-digit millisecond. latency• Optimized the scalability and resiliency of Tier-0/1 systems by resolving bottlenecks and implementing asynchronous, non-blocking libraries. Fine-tuned Kubernetes/Istio config and JVM/GC settings, achieving a 10% increase in throughput and a 25% reduction in cloud costs.• Redesigned and deployed comprehensive monitoring and alerting systems for Tier-0 services. This proactive approach reduced logging expenses by 40%.• Led the Resiliency Guild to democratize best practices across Tier-0/1 services through quarterly fail-over and rollback exercises.• Drove engineering excellence by mentoring 4+ SDEs and publishing 10+ technical articles for Expedia’s engineering blog. Championed AI-augmented productivity using Claude Code and Copilot, and built RAG-based agents during hackathons to automate customersupport workflows.
