Summary
👤
Senior🎓
Top SchoolJacky C is a machine learning engineer based in Toronto with nine years of experience applying data engineering, causal inference, and ML to production-scale problems across finance, telecommunications, and research labs. He has driven end-to-end pipelines and dimensional data models in AWS and SQL Server, cutting delivery times from a week to under a day and enabling ML on 100+ million records. His research work at Huawei improved causal model accuracy to 96% and halved runtime in 100-million-user scenarios through sampling and HDBSCAN clustering. At the Vector Institute he built a LangChain/RAG-powered chatbot on Azure that lets users query and visualize SQL data in natural language, demonstrating a blend of research rigor and practical deployment. Now at Reddit, he continues to bridge applied research and production engineering, bringing strong feature engineering, performance optimization, and data-product sensibilities. He pairs a Master’s in Data Science & AI from Waterloo with hands-on experience across the full ML lifecycle, and often surfaces non-obvious causal signals to drive business impact.
