PROFILE
Dmytro Trotsko
Over a two-month period, contributed backend features to the cmu-delphi/delphi-epidata repository, focusing on data accessibility and metadata enhancement. Developed a Geo Indicator Coverage API endpoint, enabling retrieval of geo_type and geo_value pairs across multiple data sources and signals. This involved backend query construction, data transformation, and comprehensive unit testing using Python and SQL to ensure reliability. Later, enhanced the DataSource model by adding an original_data_provider field, supporting provenance tracking and improved metadata for governance and audit readiness. Demonstrated skills in API development, backend engineering, and data modeling, with an emphasis on robust testing and maintainable code practices.
