DrawdownIQ is a full-stack market analytics and machine learning platform for exploring major S&P 500 drawdowns and estimating 180-day recovery probability. It combines a Python/PostgreSQL data pipeline, FastAPI backend, React interface, and leakage-audited ML workflow into one end-to-end product.

• Processes 1.3M+ daily price rows across 503 S&P 500 tickers

• Builds SQL-defined drawdown events and point-in-time ML features

• Includes interactive predictions, recovery analysis, and model diagnostics

• Evaluated on a 361-event chronological holdout with 0.731 ROC AUC

Pun Dialog Interpreter is an interactive NLP and LLM application that detects ambiguous wordplay, identifies competing meanings, and explains why a pun works. It combines sentence embeddings, lexical-semantic analysis, and large language models to make the final interpretation more grounded and understandable.

• Uses SBERT embeddings and WordNet sense relationships to rank candidate meanings

• Combines deterministic NLP with LLM reasoning instead of relying on a single model call

• Supports interchangeable Gemini and OpenAI providers with structured JSON outputs

• Includes retry handling, validation, error recovery, and conversational follow-up
