I build AI agents that do real work.
From prototype to production — LLM systems, multi-agent workflows, and automation that actually ships.

About
I'm Wei Tang — an engineer with a decade in machine learning and medical-imaging research, now building agentic systems.
ersiai is a one-person studio, run together with its own AI agent fleet — the same kind of systems I build for clients. Everything above was shipped this way.
