Work Experience

Software Engineer at GigaCloud Technology (NASDAQ: GCT)
January 1, 2026 - Present
Owned a sales-channel integration layer end-to-end (order ingestion through fulfillment and shipment confirmation) across 12 marketplaces handling ~40K orders/day. Built a template-method pipeline at the persistence boundary to unify validation, SKU/warehouse mapping, and transaction semantics so onboarding a new marketplace is ~2 days of mapping work instead of a full re-implementation. Diagnosed and fixed silent reporting data loss caused by granularity mismatch; rebuilt parcel persistence as one-row-per-parcel behind an idempotent state machine to guarantee exactly-once reporting with no partial or duplicate writes. Built order/shipment synchronization feeding downstream accounting with an outbox-backed transactional sync (backfilled 1M+ orders and 3M+ parcels in ~10 hours) and incremental convergence. Isolated permanently failing records into a dedicated retry job to prevent head-of-line blocking and added alerting for stuck records. Reduced bulk freight quoting latency 20× (60s
Software Engineer at Huawei Technologies
September 1, 2024 - November 30, 2025
Built Auto OnCall, an LLM agent platform adopted by a 30-engineer team. The AIOps agent chains alert ingestion → knowledge retrieval → planning → tool invocation → root-cause analysis → remediation using a Plan-Execute pattern with LangChain/LangGraph, replacing manual triage and reducing incident response from hours to minutes. Designed and implemented an end-to-end RAG pipeline (vector storage, indexing, chunking, retrieval, generation) and tuned chunk size and TopK to reach 85%+ retrieval accuracy on real operational queries.
Software Engineer at China Post
July 1, 2022 - June 30, 2024
Built and maintained backend features for enterprise OA and logistics systems using Java and MySQL, including order processing workflows, operational management modules, and internal service APIs. Improved reliability of long-running platforms through refactoring, SQL/index optimization, and production issue resolution.
