A retrieval-first RAG system that refuses to answer rather than hallucinate. Cosine-similarity threshold gating happens before any generation call, and the model never sees a prompt it cannot back up. Evaluated against a small set of golden test cases — calibrated to err on the side of silence.

Docker-sandboxed multi-language code execution platform. Submissions enter a Redis-backed BullMQ queue, are executed in isolated containers with strict resource limits, and stream results back to the user. Designed to be both safe and fast.

An LLM-assisted dynamic pricing engine for small e-commerce operators. Combines competitor signals, demand curves, and a constrained generation step to produce price recommendations with reasoning. Selected as a Top 10 entry of 300+ in the Google Cloud Build & Blog Marathon.
