TALENT SYNC AI CHAT BOT - RESUME AND PROJECT DOCS ANALYZER

The “Talent Sync AI Chat Bot - Resume and Project Docs Analyzer” is a smart AI-powered chatbot system designed to interactively analyze and provide insights from large repositories of unstructured documents stored in Amazon S3. Whether it’s thousands of resumes, HR spreadsheets, or project documentation files, this solution leverages natural language interfaces to extract valuable answers from these documents. Users can query the system with everyday language questions like “Who has Node.js experience?” or “What server is used for this application?”, and the chatbot returns precise, contextual answers. Built using Amazon Bedrock, Amazon Lex, AWS Lambda, and secured via IAM and S3, this system is intended to be scalable, intelligent, and highly secure.

  • Enables HR teams and project managers to quickly find relevant skills and information without manually browsing through thousands of files.
  • Leverages Amazon Bedrock for generative AI, Amazon Lex for conversational interface, and AWS Lambda for backend logic with secure storage in S3.
  • Architecture focuses on scalability, automation, and fine-grained security with IAM roles and policies.
