PROFILE
Tenzin Choedon
Tenzin Choedon developed and enhanced data processing infrastructure for the IMAP-Science-Operations-Center/sds-data-manager repository, focusing on reliability and resource management. Over three months, Tenzin implemented features such as Time Kernel Integration for L0 data processing, batch job timeout policies, and resource scaling for processing jobs. Using Python, AWS CDK, and AWS Lambda, Tenzin improved data reliability by integrating time kernels and handling leap seconds, while also introducing batch timeouts to prevent runaway executions. The work included scaling memory and CPU allocations, refining error reporting, and extending Lambda timeouts, resulting in more predictable, robust, and maintainable data processing pipelines.
