Could you build this?
No Building a single-binary memory engine with sub-10ms latency requires deep systems engineering in languages like Rust or C/C++, custom memory indexing, and concurrent storage engines.
What it would actually take: A production engine requires implementing an embedded key-value or graph store alongside an approximate nearest neighbor (ANN) vector index like HNSW in Rust or C++. Achieving reliable sub-10ms query execution across combined vector similarity and symbolic filtering requires meticulous memory layout, zero-copy serialization, and lock-free concurrency. It necessitates specialized systems performance and database kernel engineering skills.

Same idea, different domain
Nobody's really built a model & infra tool for Fintech yet.
