At uhomes, I led the end-to-end rewrite of a core listing data pipeline from PHP to Go, owning a dozen services supporting listing digitization that covers 67.5% of revenue and 59.2% of closed orders. I migrated crawler workloads, consolidated database access behind gRPC, and established protobuf contracts with breaking-change checks.
I build practical AI systems into production workflows: LLM-based room and unit normalization with ROI instrumentation, a Claude Vision-powered order pre-check that replaces manual review for 300+ orders daily, and an in-house AI Code Review rolled out across 37 Go projects.
Previously at Qingfeng, I shipped 300+ requirements for HeyChat and HeyBox, products serving a gaming community with 5M daily active users. I owned microservices for voice social features, messaging, campaigns, bots, OAuth, dashboards, and internal systems while resolving production issues including PostgreSQL connection-pool exhaustion and Redis shard imbalance.
I'm comfortable taking backend systems from scaffolding to observability: Go, gRPC, Kafka, PostgreSQL, Redis, Prometheus, Grafana, CI/CD, and Docker. I enjoy decoupling services, governing data safely, and making engineering teams faster with reusable infrastructure and AI-assisted development.
