I chose TypeScript with Express for the API, VTest for testing, and an in memory store, splitting the code into a parser, storage, and API. In the parser I added strong type checking and validation for chromosomes, alleles, header parsing, and column order invariants. The server runs on port 3000, replaces genetic data on upload, and creates the store at startup so a restart clears data. I do not have any specific action requested from viewers.
