Mason Tian

AI Engineer @ Emergent Solutions

About

I am a Full-stack AI Engineer with experience building production-grade AI systems, SaaS platforms, and workflow automation products. I’ve worked across backend systems, cloud infrastructure, and AI pipelines using LLMs, OCR, and vision-language models to power real document intelligence and automation workflows in regulated environments. In my previous roles, I designed and shipped scalable multi-tenant systems, backend orchestration services, and distributed worker architectures on AWS, handling high-volume processing and complex business logic end-to-end. I also have experience building AI agent workflows, RAG-style pipelines, and integrating LLMs into production systems with a focus on reliability and performance. My strength is turning complex business problems into scalable technical systems, and I enjoy working in fast-moving startup environments where I can own architecture, ship quickly, and build from zero to production.
