Summary
👤
Senior🎓
Top SchoolXiaojian Deng is a Senior Software Engineer specializing in AI and data engineering with a decade of experience blending machine learning, quantitative finance, and practical automation. He builds end-to-end, high-leverage systems—particularly applied LLM workflows, RAG pipelines, and generative model tooling—that turn messy document and content problems into reliable, user-friendly products. Past roles include deploying robust RAG and document-matching systems for financial workflows, prototyping fraud detection with high recall in insurance, and fine-tuning models to run on constrained hardware. He pairs strong hands-on engineering (from model training and evaluation to production inference) with a knack for simplifying complex processes for non-technical users. Notably, he has driven creator-focused ML products that reached top revenue tiers and has adapted reinforcement and ensemble methods for live trading and risk systems. Based in Boston, he combines academic depth in computational engineering and financial engineering with a practical, results-oriented approach to applied AI.
