Andrew Sheridan is a Senior Software Engineer based in Boston with eight years of experience building high-performance, data-focused systems for finance and analytics. Currently at Pazien, he applies expertise in cloud-scale architectures and transaction monitoring honed at Jumio—where he engineered a 100x speedup in suspicious-activity detection—and at MassMutual, where he led schema management, Spark processing, and encryption-focused data pipelines. Comfortable across backend services, distributed data platforms, and ML preprocessing, he blends hands-on profiling and refactoring with pragmatic automation to improve reliability and throughput. A UC Berkeley-trained physicist with roots in tutoring and mentorship, he brings a rigorous, measurement-driven approach and a knack for turning research techniques into production-ready tooling.
