I am an AI/ML Engineer with deep expertise in Natural Language Processing (NLP), Language Model Architecture, and AI System Design. My experience spans the complete lifecycle of AI solution development — from research and model implementation to scalable system integration and optimization for production environments.
Retrieval-Augmented Generation (RAG): Designed and implemented end-to-end RAG pipelines from scratch.
Text Generation: Built custom decoding strategies including greedy decoding, beam search, and length normalization.
Embeddings & Vector Search: Hands-on with TF-IDF, cosine similarity, and semantic search workflows.
Tokenization Strategies: Proficient with word-level, subword (BPE), and character-level tokenization techniques.
Decoding Strategies: In-depth understanding of greedy vs beam search trade-offs.
Context Management: Developed chunking and overlap handling strategies for large-text processing.
Performance Optimization: Skilled in batch processing, efficient memory usage, and runtime improvements.
Clean, modular OOP design with robust exception handling, type hints, and professional documentation.
Expertise in PDF text extraction (PyMuPDF, pdfminer), normalization, pattern recognition, and sentence/paragraph chunking.
Libraries & Frameworks:
NumPy — mathematical computation and data manipulation
FAISS — vector database integration for semantic retrieval
SentenceTransformers — embedding generation and semantic similarity
FastAPI — architectural understanding for API-based NLP services
Logging & configuration for production-grade setups
Emphasis on modularity, scalability, and centralized configuration management.
Production Readiness (Intermediate–Advanced):
Incorporates performance benchmarking, graceful error handling, and well-documented deployment pipelines.
Skilled in similarity metrics, ranking algorithms, and top-k retrieval with domain-specific adaptations.
Text Analytics (Intermediate–Advanced):
Experienced in TF-IDF, vocabulary analysis, pattern recognition, and high-quality content extraction.
Designed and implemented a complete Retrieval-Augmented Generation (RAG) system for processing 1000+ technical documents, creating an intelligent Q&A system for aviation regulatory compliance using ICAO Airworthiness Manual data.
✅ Built end-to-end RAG pipeline processing 2,738 document chunks from 1.8M+ characters of technical content
✅ Achieved 60-70% code reusability by adapting Stanford CME 295 lecture components for production use
✅ Implemented multiple tokenization strategies (word-level, BPE subword, character-level) with OOV risk analysis
✅ Developed semantic search system with TF-IDF embeddings achieving 0.3-0.5+ similarity scores for relevant queries
✅ Created production-ready architecture with modular design, comprehensive error handling, and scalable configuration
PDF Extraction: Implemented multi-backend system (PyMuPDF, pdfminer) with batch processing for 1000+ documents
Text Cleaning: Developed intelligent preprocessing removing headers, footers, page numbers with 13.9% text reduction
Document Chunking: Created sentence-aware chunking strategy generating optimal 964-token segments with 200-token overlap
Embedding Generation: Built TF-IDF vectorization system with 1000-term vocabulary from domain-specific content
Vector Database: Implemented FAISS-based similarity search with cosine distance metrics
Text Generation: Integrated greedy and beam search decoders with length normalization and confidence scoring
Modular Design: Structured codebase with 5 core modules (data_processing, embeddings, generation, rag, core)
Configuration Management: Centralized settings for PDF processing, chunking, embeddings, and generation parameters
Error Handling: Comprehensive exception management with detailed logging and graceful failure recovery
Processing Speed: 20 seconds to generate embeddings for 2,738 chunks
Query Performance: <1 second response time for semantic search queries
Accuracy: High relevance retrieval with similarity scores 0.3-0.5+ for domain-specific queries
Scalability: Architecture supports expansion to 10,000+ documents with minimal modifications
Languages: Python 3.8+
AI/ML: Custom transformer components, TF-IDF embeddings, FAISS vector database
Libraries: NumPy, PyMuPDF, pdfminer.six, sentence-transformers (architecture), FastAPI (designed)
Architecture: Object-oriented design, modular packaging, configuration-driven development
Aviation Regulations: Deep understanding of ICAO airworthiness standards and compliance requirements
Technical Documentation: Processing complex regulatory manuals with specialized terminology
Knowledge Management: Creating searchable knowledge bases from unstructured technical content
Complete RAG System - Production-ready codebase with 15+ Python modules
