About Wenhanfu Yang

I’m Wenhanfu Yang, a recent Computer Science graduate from Northeastern University, currently seeking backend software engineering opportunities.My technical background includes experience with Spring Boot, Flask, MySQL, and RESTful APIs. I enjoy building scalable backend systems and solving real-world engineering challenges. I’ve also solved over problems on LeetCode, which reflects my strong foundation in algorithms and problem solving.I previously interned at Huawei as a full-stack developer, where I maintained a financial system used in developing countries and resolved 7 production issues that were successfully integrated into the company’s codebase.More recently, I worked at an AI startup focused on e-commerce automation. There, I contributed to backend integrations with platforms like TikTok and Gorgias, maintained a RAG knowledge base, and fine-tuned prompt performance for AI-powered customer support.I’m excited to bring my skills and energy to a team where I can continue growing as a backend engineer.
