I've built and modernized PHP and Go services for booking, payment, healthcare, IM, financial, live-streaming, and data collection products. Most recently, I designed a multi-room reservation backend with order, inventory, and payment workflows, cutting database load by approximately 60% through Redis caching and sustaining 500–800 QPS at peak.
I've extracted payment capabilities from a PHP monolith into an independent Go microservice using go-zero, Kafka, Redis, and TiDB, including wallet, top-up, and unified RPC payment services. I also designed healthcare platform modules connecting a WeChat Mini Program with clinic workflows and role separation for patients, doctors, and service providers.
I focus on API design, relational data modeling, transaction consistency, caching, concurrency, and production performance tuning. My project work includes a concurrent Go web crawler, a Gin-based live-streaming backend with WebSocket chat and Nginx RTMP, and vehicle diagnostics services using FastAdmin and Workerman.
