PROFILE
Tenzin Choedon
Worked on the IMAP-Science-Operations-Center/sds-data-manager repository, delivering four features over three months to enhance data processing reliability and infrastructure stability. Focused on integrating time kernel support for L0 data processing, improving data timeliness and error reporting by configuring leap second and spacecraft clock handling. Introduced a batch processing timeout policy to prevent indefinite executions, supporting predictable resource usage and SLA adherence. Enhanced processing job scalability by adjusting memory, CPU, and Lambda timeouts, reducing failure risks and improving throughput. Leveraged AWS CDK, AWS Lambda, and Python to implement infrastructure as code and robust pipeline development, emphasizing maintainable, traceable change management.
