AI Resume Parser & Builder (LLM + NLP SaaS Platform) integrated with Dynamics 365 and AI Music Lyrics Generation Prototype

• Developed a hybrid AI resume parsing system using SpaCy and GPT-4o-mini, achieving 95–98% structured data completeness for PDF and DOCX resumes.
• Built a full-stack AI SaaS platform (Next.js frontend + FastAPI backend) featuring an interactive resume builder with real-time preview and customizable templates.
• Implemented ATS scoring (0–100) and job description matching algorithms to analyze candidate-job alignment and generate optimization insights.
• Integrated PostgreSQL + pgvector semantic search for intelligent candidate matching and automated profile creation within the company's live recruitment platform.
• Scaled the system to process 6000+ resumes, generating 5700–5880 fully structured outputs in 7.2 hours with $14 API cost, demonstrating high scalability and cost efficiency.
• Built a RAG-based lyric generation system using Python and FAISS, enabling context-aware music lyric generation.
• Designed data preprocessing and structured dataset pipelines (JSON/JSONL) to improve generation quality and consistency.
• Delivered the prototype as a client-facing proof-of-concept for product demonstrations and internal evaluation.
