Industry Classification & Mapping Service
Modernizing industry taxonomy services and mapping data
Worked on migrating industry classification lookups from legacy Hivemind GraphQL integrations toward an asynchronous FastAPI Industry Service. Built and validated NAICS, GICS, NACE and SIC mapping updates, parent hierarchy corrections, industry-name updates and SQL migration scripts while preserving stable identifiers and checking cross-environment data consistency.
