Hi, I’m a Software Engineer, AI Product Manager, Full-Stack Web Developer
Allen Shan.
Based in Los Angeles, I'm a product-minded engineer who spots repetitive work and messy workflows, then builds full-stack and AI tools that make life easier—from sales analytics platforms to intelligent agents. I love working on tech that makes a real business impact and meeting people who are just as excited about building and solving problems.
