Top SchoolJessica Fan is a seasoned software engineer with 11 years of experience building ML platforms and cloud-native data infrastructure, currently contributing at Square's ML infra team. She blends deep expertise in data engineering (Airflow, Spark, Hadoop, AWS/GCP), software development (Python, Java, Scala, C++, JavaScript), and infrastructure-as-code (Terraform) to run production-grade pipelines and services. Her background includes shipping cloud migrations and data platforms at Etsy, automating ETLs and privacy tooling at Two Sigma, and leading platform work as a principal engineer at Curology. Comfortable across the stack, she has practical DevOps chops—"terraformed her fingers away"—and has implemented monitoring, CICD, and secure deployment patterns at scale. Trained in Computer Science with a focus on ML at Columbia, Jessica pairs technical rigor with creative interests in painting and music, an unusual blend that fuels pragmatic, user-aware engineering.
