Chad Heyne is a software engineer specializing in data infrastructure with 12 years of experience building analytics-driven systems at Indeed from BI to senior engineering roles. He blends a strong statistical foundation (BS in Statistics) and an MSBA in Finance with practical Python engineering skills to turn messy, large-scale datasets into reliable, production-ready pipelines. At Indeed he progressed from Business Intelligence to Data Engineering and now focuses on infrastructure that powers data products and decision-making. He also contributes to prominent open-source projects such as PyMC, where he helped modernize the codebase for Python 3 compatibility—demonstrating attention to portability and long-term maintainability. Based in Austin, Chad pairs quantitative rigor with pragmatic engineering, comfortable moving between statistical modeling, data cleaning at scale, and backend code improvements.
