Senior🎓
Top SchoolCarl Yeksigian is a senior software engineering manager with 13 years of experience building distributed query and data platforms, currently leading Query Execution teams at Datadog. He blends hands-on systems work—contributing to Apache Thrift and Apache Cassandra—with productionizing big-data bioinformatics pipelines via the ADAM project using Spark, Parquet, and Avro. Carl has driven planner and optimizer development (Calcite, Substrait) and multi-engine query routing (Trino, DataFusion), balancing open-source collaboration with delivering customer-facing observability capabilities. His background spans finance, genomics, and cloud-scale engineering, showing a knack for porting research code into robust, S3-backed production systems. Colleagues know him for bridging compiler- and protocol-level detail work with high-level architecture and for pragmatic fixes that improve cross-language portability in widely used OSS projects.
