• Architected a full-stack SaaS platform (FastAPI backend, Next.js frontend, separate ML service) with JWT

authentication and role-based access control, backed by a pytest test suite covering API, forecasting, and

recommender logic.

• Implemented LightGBM demand forecasting with Optuna hyperparameter optimization and lag/rolling window

features for time-series prediction.

• Built a RAG-based AI assistant using Groq Llama 3.3 70B and pgvector for semantic retrieval over menu and

operational data, with a hybrid co-occurrence and content-based recommender system
