end-to-end AI product delivery
An AI application engineer focused on control, evidence, and production delivery.
AI application engineer with 7+ years of product engineering experience. I work across PC, desktop, browser, and Office/WPS surfaces, editor interaction, Django/FastAPI services, Agent workflows, retrieval, and production delivery.
My focus is turning probabilistic model output into controllable product behavior: confirmable workflows, grounded evidence, version-aware mutations, recoverable failures, and observable runtime systems.
