About me
Hi, I am Yu Bing. I am an AI SaaS backend developer. If you need AI powered APIs, payment systems, or cloud infrastructure, you are in the right place.
I build scalable backends with Java 21, Spring Boot, Python FastAPI, and Docker. My project NovelTrans runs multi agent AI workflows, RAG memory, Stripe subscriptions, and real time processing.
I help founders launch faster through solid backend architecture, not shortcuts. I work through Fiverr chat only. No calls, every detail recorded.
Feel free to message me with your API or infrastructure needs.
