    LLM systems · safety-critical routing

    A multi-stage AI triage pipeline built on LLM structured outputs — classifying incidents, generating de-duplicated follow-up questions, and synthesizing incident records — with deterministic fallback logic for graceful degradation when models fail. A safety layer independent of the LLM force-escalates life-critical hazards, and a six-state routing-readiness engine gates automated dispatch on AI confidence, evidence completeness, cost tier, and tenant responsibility.

    Backend architecture · billing & auth

    A modular FastAPI backend spanning multiple services for investment analysis, portfolio management, billing, and mobile APIs. Includes Stripe-based subscription and entitlement infrastructure with webhook-driven billing updates and idempotency safeguards, hardened Google OAuth with resource-ownership authorization, and core workflows for deal versioning, stress testing, and actual-vs-projected performance evaluation.

    ML systems · model serving

    Translates survival-analysis research (MTLR, individualized survival distributions, conformal prediction) into production ML services. End-to-end pipelines cover preprocessing, model training, calibration, and evaluation, served through a scalable model-serving API that decouples real-time probabilistic inference from application logic.
