Hi, I’m Roy (Huayi) Luo, a software engineer who loves building AI tools and exploring new tech.
I’m currently working at Alpha Vantage (YC S18), where I build AI-powered financial tools. I work on trading-agents.ai, Alpha Vantage's deployment of TradingAgents — a multi-agent LLM framework for financial trading analysis, with added deployment infrastructure and UI. I also built the Alpha Vantage MCP Server to bring market data into the AI agent ecosystem.
On the side, I build personal AI infrastructure. y-agent is my toolkit for orchestrating AI agents — it powers my daily workflow through Telegram and Claude Code integration.
Previously, I worked at Zhipu AI, Alibaba Cloud, and BizSeer. I graduated from Tsinghua University in 2019 with a degree in Computer Science.
