An agent that drives the whole ML lifecycle through a 20+ tool MCP registry behind human approval gates, running every model-generated cell inside a hardened Docker sandbox with no network, a read-only rootfs, and a non-root user. The preprocessing path is marked a scaffold, not claimed as shipped.

A multi-stage NLP smart-input pipeline (chrono-node, compromise, and a custom priority parser) that resolves overlapping parser claims by priority first, then per-tag confidence. The serverless path dropped Prisma for raw pg, while a parallel Express + Prisma stack still ships alongside it.

An MLP whose hot paths are hand-vectorized with arch-dispatched AVX-512, AVX2, and NEON kernels over 64-byte-aligned, blocked-tiled matrices, no BLAS or PyTorch pulled in. OpenMP wins on big matrices and regresses small ones ~7x, so it is gated by size, not waved off.

A C++23 expression language compiled to WebAssembly: tokenizer, recursive-descent parser, tree-walking evaluator, user functions, and recursion. It is the engine parsing the headline at the top of this page. It uses double everywhere with exact == checks, simple and stated outright.
