Saurabh S.

I help companies build production-grade AI systems. With 9+ years of experience in AI/ML, I specialize in Document AI, OCR pipelines, Retrieval-Augmented Generation (RAG), and LLM-based agents used in real businesses across banking, healthcare, manufacturing, and e-commerce. If you’re struggling with unstructured data, PDFs, scanned documents, hallucinating LLMs, or brittle prototypes, I can help you take it to production. What I Build: 🔹 Document AI & OCR Systems • Invoice, contract, COA, compliance & regulatory documents • Custom OCR pipelines (AWS Textract, Azure Document Intelligence, PaddleOCR) • Layout-aware extraction using LayoutLM, custom CV + NLP hybrids • Entity extraction, tables, multi-page documents, noisy scans • Deployed at scale in banking & manufacturing environments 🔹 Retrieval-Augmented Generation (RAG) Systems • Enterprise RAG using Azure AI Search, Pinecone, Neo4j • Hybrid search (vector + keyword), metadata filtering, reranking • Query rewriting, HyDE, self-reflection loops to reduce hallucinations • Multi-source retrieval (databases, PDFs, Shopify, Gorgias, internal docs) 🔹 LLM Pipelines & Agentic Systems • Multi-step LLM workflows with evaluators & guardrails • LangChain, LangGraph, Semantic Kernel • Structured outputs with function calling & schema enforcement • Fine-tuned LLaMA-3 (LoRA) for domain-specific extraction & reasoning • Cost-optimized pipelines (caching, async execution, retries) 🔹 Computer Vision • HP Singapore: printer component inspection systems • Object detection, image classification, defect detection • Models deployed in real manufacturing workflows 🔹 Speech AI • Whisper fine-tuning for noisy & impaired speech • Real-time transcription pipelines • Voice cloning & synthesis (ElevenLabs-based systems) Tech Stack: Python, PyTorch, FastAPI, Docker LangChain, LangGraph, Semantic Kernel OpenAI, Claude, LLaMA-3, Whisper Azure AI Search, Azure OpenAI, Azure Document Intelligence AWS Textract, ECS, Lambda Pinecone, Neo4j, PostgreSQL Industries I’ve Worked In Banking • Healthcare • Manufacturing • E-commerce • Food-Tech Why Clients Hire Me • I’ve taken AI systems to production, not just notebooks • I understand failure modes: hallucinations, OCR noise, bad retrieval • I design systems that are scalable, debuggable, and cost-aware • I can work independently and think like an AI architect, not just a coder If you need someone who can design, build, and own an end-to-end AI system, let’s chat.
