Summary
👤
Senior🎓
Top SchoolYan Jiang is a software engineer with 10 years of experience building data-driven systems and scalable pipelines across Meta, Apple, and Capital One, blending strong data-mining/statistics expertise with production-grade engineering. Trained in environmental engineering and data mining (Purdue), she applies statistical rigor—bootstrapping, PCA, Monte Carlo—to large-scale problems and has built ETL and automation tools for national-scale datasets. At Meta she contributes to core developer tooling and has made notable open-source fixes to Facebook's Relay compiler, improving transformations and watch-mode stability. Her background in ecosystem modeling and published forecasting work gives her an unusual strength in turning noisy, spatial-temporal science data into reliable software products. Based in San Jose, she pairs big-data tech (Spark, Hadoop, AWS, Elasticsearch) with practical ML feature-selection experience, bridging research and production.
