2026-03 monthly summary for radiant-portal focusing on performance improvements, data integrity, and CI/testing efficiency. Key features delivered include batch processing performance improvement via batch worker caching to reduce redundant Postgres calls during case validation; addition of a Buffy coat sample type with validation updates and a corresponding database migration; and parallelized testing with CI optimization to speed up feedback cycles. Major bug fix implemented a validation to enforce single aliquot for exomiser and alignment_germline_variant_calling, with error handling for multiple aliquots to improve data integrity. Parallelized tests and conditional CI runs reduced build and test times. Overall impact: reduced data retrieval latency in batch processing, faster validation cycles, and stronger data integrity, enabling more reliable processing and quicker business decisions. Technologies/skills demonstrated: caching strategies, database migrations, robust validation/error handling, test parallelization, and CI workflow optimization, with emphasis on Postgres query optimization and performance-driven development.
