What I'm looking for

I'm looking to build high-concurrency web applications and AI-driven products, particularly in fintech or regulated industries, where I can apply Python, Django, Vue, RAG, AI agents, and cloud infrastructure.

At Ant Group, I architected and upgraded a core financial trading platform, improving page load speed by 40% and reducing PostgreSQL P99 latency from 800ms to 150ms. I also built an LLM and RAG-powered customer service and data analysis assistant that achieved 92% answer accuracy.

I previously built secure internal systems at Tencent using Python, Django, Vue, and TypeScript. Across fintech and regulated environments, I develop AI agents, scalable APIs, search systems, automated testing, and AWS infrastructure for high-concurrency products.
