What I'm looking for

I'm open to worldwide remote contract roles with EU/US time-zone overlap, where I can build scalable PHP backends, real-time platforms, payment systems, and high-performance APIs while contributing to architecture and technical delivery.

I've built PHP platforms at Nanjing Xunyou Technology serving more than one million users, keeping core API response times below 50 ms and increasing tested load capacity by more than 5×.

I lead architecture and delivery while continuing to write critical production code. My work includes Webman backends, Vue administration tools, recommendation systems, and integrations with Shumei, Agora, NetEase IM, and Tencent IM.

Previously, I led PHP and front-end engineers at Guangzhou Hesheng Network, where I developed reusable ThinkPHP components, introduced structured code review and PSR practices, and delivered real-time audio, video, and messaging capabilities.

I've also built Workerman messaging systems, CRM workflows, automated content collection pipelines, and Swoole-based payment systems processing more than RMB 30 million monthly and sustaining over 4,300 requests per second on a single server.
