   LLMsRAGGoReactGraphQLAWS CloudFront

   AI initiative

   • Architected an AI-driven capacity management system that turns candidate and job data into strategic recommendations with LLMs and Retrieval Augmented Generation.
   • Built an agent chaining and orchestration workflow linking candidate recommendation with risk assessment and financial impact estimation.
   • Engineered a RAG module over vector embeddings of historical recruitment data so prompts carry real past outcomes as context.
   • Designed a two-stage prompting strategy: filter on core criteria first, then refine on risk factors and constraints.
   • Wrote synthetic data pipelines producing interconnected candidate, position and history datasets for training and testing.
   • Added human-in-the-loop checkpoints for low-confidence outputs, feeding back into prompt thresholds and agent logic.
