The Room aims to connect top talent globally through a technology-driven platform, leveraging entity-matching algorithms to quickly find high-quality candidates. The core challenge is a mathematically difficult problem requiring accurate and relevant matching of entities, which was addressed by using vector space embedding and combining it with business logic. Redis' high-performance key retrieval based on nearest neighbour vector lookup significantly improved the computation loop, achieving over 15 times speedup without memory overhead. The implementation utilized Scribble Data's Enrich feature store, which handled integration with various data sources, data quality, and batch processing, among other tasks. The optimization focused on reducing resource intensiveness, optimizing for compute distribution, and addressing key constraints such as low latency and high-performance vector similarity computation.
