Are missed calls, slow follow ups, or manual lead handling costing your business opportunities? I help businesses build custom AI voice agents and automation systems that answer calls, qualify leads, schedule appointments, and follow up automatically so your team can focus on closing deals instead of chasing conversations. Many businesses in real estate, healthcare, and service industries lose potential clients simply because they cannot respond instantly. I build AI voice systems that handle conversations 24/7, while keeping everything synced with your CRM and workflows. My focus is simple: build AI systems that actually work inside real business operations. ๐€๐ˆ ๐•๐จ๐ข๐œ๐ž ๐€๐ ๐ž๐ง๐ญ๐ฌ & ๐‚๐š๐ฅ๐ฅ ๐€๐ฎ๐ญ๐จ๐ฆ๐š๐ญ๐ข๐จ๐ง I design and deploy AI voice agents that handle real customer conversations, book appointments, qualify leads, route calls, and trigger follow-up actions automatically.

โญ TOP RATED | 100% Job Success | AI Agents, RAG Chatbots, OCR & Document AI I build production-ready AI systems that pay for themselves: I saved a fintech client โ‚ฌ40,000/year by automating their KYC pipeline (99%+ extraction accuracy) and cut clinical documentation time by 60% with an AI medical scribe inside a live EMR platform. If you have messy documents, manual workflows, or an agent/chatbot idea that needs to actually work in production โ€” not just in a demo โ€” I can ship it fast without sacrificing accuracy or scalability. WHAT I BUILD ๐Ÿ”น AI Agents & Multi-Agent Automation โ€” autonomous, decision-making agents with LangChain, LangGraph and CrewAI that automate real backend processes: document review, support, lead handling, internal ops. ๐Ÿ”น RAG Chatbots & Knowledge Assistants โ€” retrieval-augmented generation chatbots over your PDFs, docs and databases. Hybrid GraphRAG (Neo4j) + vector search for grounded, accurate answers with strict guardrails against hallucination. ๐Ÿ”น OCR & Document AI โ€” invoice, ID and form data extraction with PaddleOCR, AWS Textract, YOLO and LayoutLM. 99%+ extraction accuracy on IDs, invoices, tables and unstructured documents. ๐Ÿ”น Healthcare AI & EMR Automation โ€” HIPAA-compliant medical scribes (Whisper speech-to-text, speaker diarization, auto-generated SOAP notes and ICD-10 codes), wound-analysis computer vision, clinical RAG with PII redaction. ๐Ÿ”น KYC & Identity Verification โ€” document localization, MRZ parsing, ArcFace biometric matching, liveness detection, real-time transaction risk engines. RESULTS CLIENTS PAID FOR - โ‚ฌ40K/year saved โ€” automated fintech KYC pipeline (OCR + face match + verification agents) - 60% less documentation time โ€” AI medical scribe running in a production EMR - 40% accuracy uplift โ€” hybrid GraphRAG retrieval for complex financial queries - 10x faster document processing โ€” logistics and finance workflows - Sub-200ms retrieval latency โ€” FastAPI microservices with Redis caching TECH STACK Python, FastAPI, Docker, AWS, GCP | LangChain, LangGraph, CrewAI, OpenAI, Claude, Hugging Face | Pinecone, FAISS, Weaviate, Neo4j, MongoDB, Redis | OpenCV, YOLO, PaddleOCR, Tesseract, LayoutLM | PyTorch, TensorFlow HOW I WORK Fast execution with production discipline: clear milestones, regular updates, clean documented code, containerized deployment. I use modern AI dev tooling (including Claude Code) to ship in days what normally takes weeks โ€” without cutting corners on architecture. If you want an AI system that works in production, send me an invite or message and let's scope it in a quick call.
