deterministic guardrails

An enterprise AI copilot that drafts high-fidelity customer support replies using RAG-retrieved brand knowledge and a deterministic policy engine that auto-escalates out-of-policy requests instead of letting the model hallucinate decisions, backed by multi-tenant isolation via Supabase Row-Level Security.

ARCHITECTURE // DATASTRAW-CX

Customer inbound triggers tenant verification, hybrid vector lookup, deterministic policy validation, and multi-tier LLM generation.

SDT Math
deterministic explainable scoring

A comprehensive 11-task clinical cognitive assessment platform built for a practicing clinical psychologist at a Mumbai hospital. Evaluates 5 core cognitive domains using Signal Detection Theory (d' and response bias) and regression vigilance tracking to ensure 100% explainable diagnostic metrics, with native React components eliminating SSR hydration crashes.

ARCHITECTURE // COGNITIVE-ASSESSMENT

Time-locked patient tasks stream millisecond telemetry to the deterministic Signal Detection Theory engine for clinical report generation.
