Senior Backend Software Engineer with 10+ years of experience building high-concurrency, distributed systems using Go and Java. I specialize in designing scalable backend platforms, asynchronous workflows, and API-driven services for complex, event-driven environments. I have worked on large-scale systems handling high QPS and asynchronous workloads, with a strong focus on reliability, observability, and performance optimization. My experience includes building cloud-native services, integrating workflow orchestration, and implementing monitoring and tracing using tools such as OpenTelemetry, Prometheus, and Grafana. I enjoy collaborating with cross-functional teams to deliver clean, maintainable solutions and can quickly adapt to new domains, tools, and architectures to meet business needs.…Senior Backend Software Engineer with 10+ years of experience building high-concurrency, distributed systems using Go and Java.

Work Experience

Senior Software Engineer at Huawei Technologies Co., Ltd (Client - Embedded, Cloud)

September 1, 2024 - August 1, 2025

Delivered SDN solutions for enterprise customers, including pushing control instructions using gRPC bidirectional streaming, routing computation via master-slave coordination, and cluster scalability evaluation. Standardized a common Go middleware library, reducing project initialization time from half a day to 10 minutes and refactoring ~80% of related code. Improved computation performance, reducing runtime from 10s to 1s+ at 1,000-node scale through profiling (pprof), concurrency tuning, and resource scheduling. Implemented end-to-end CI/CD pipelines using Huawei Cloud CodeArts, containerized services via Docker Compose and CCE, enabling faster, reliable automated delivery.

Senior Software Engineer at ByteDance Technology Co., Ltd

November 1, 2021 - April 1, 2023

Developed logistics governance system, integrating 12+ upstream services, handling 200K+ asynchronous throughput across three data centers (3-IDC). Spearheaded a service refactor involving 5+ teams, achieving a zero-downtime migration. Reduced event processing latency 8h → 30min via pre-filtering, throttling, and load balancing. Strengthened payment pipeline with automated circuit breaking & reconciliation, achieving ~90% event detection coverage.

Lead Backend Software Engineer at Yuanli Education Technology Co., Ltd

November 1, 2015 - November 1, 2021

Led a 7-member backend team; migrated 100+ microservices to cloud with zero downtime. Ran distributed scheduling jobs for online tasks, used distributed locks handling concurrency and adopted BASE for distributed transactions. Designed resilient core services achieving 99.9% uptime and <50ms latency through caching, concurrency control, asynchronous processing, rate limiting, and service degradation strategies. Implemented real-time WebSocket push services for game events and live-room barrage, supporting up to ~10K concurrent connections with optimized connection lifecycle management and message fan-out. Owned VIP membership system (~10K new daily users); introduced JWT-like tokens & caching to cut DB load by 20 – 30K QPS.
