Experience
Beijing
- Architected next-gen real-time settlement gateway with Go, gRPC, and Kafka, scaling peak throughput to 120k+ QPS with 14ms P99 latency
- Designed database sharding (32 DBs, 1024 tables) and ES near-real-time index pipeline for financial ledgers, boosting query throughput by 4x
- Implemented multi-tier caching with Redis Cluster & in-memory BigCache, reaching 99.4% cache hit rate and reducing DB load by 70%
- Devised Saga distributed transaction orchestrator with automated reconciliation, processing 80M daily transactions at 99.999% SLA
Beijing
- Migrated legacy monolithic service into 18 Go microservices on Kubernetes & Istio, increasing deployment velocity from 1/week to 15+/day
- Developed Raft-based distributed configuration & rate-limiting hub, flawlessly withstanding 5x holiday traffic spikes
- Conducted deep pprof memory & GC profiling to eliminate allocation bottlenecks, slashing process memory footprint by 38%
