Hire the Best OCR Tesseract Specialists

Senior AI Automation Engineer with $300K+ earned, 20,000+ Upwork hours, 365 completed jobs, and 12+ years of experience in Python, AI agents, API integration, and web scraping. I build reliable production systems not fragile demos. Clients hire me to turn manual workflows, scattered data, or early AI prototypes into dependable software that saves time, improves accuracy, and can be maintained by their team. WHAT I BUILD • AI Agents & LLM Applications OpenAI, Claude, and Gemini integrations; structured outputs, tool calling, memory, prompt engineering, multi-agent workflows, MCP, confidence controls, and human approval steps. • RAG & Document Intelligence Knowledge assistants, embeddings, vector search, PDF/DOCX/image processing, OCR, classification, validation, and structured exports to Excel, CSV, JSON, or databases. • Business Process Automation n8n, Make, Zapier, REST APIs, OAuth, webhooks, email, Google Sheets, calendars, CRMs, Slack, Telegram, and WhatsApp integrations. • Web Scraping & Browser Automation Scrapy, Playwright, Selenium, Requests, and BeautifulSoup for dynamic websites, login workflows, pagination, monitoring, large-scale crawling, proxy rotation, and clean structured datasets. • Backend Systems & Dashboards FastAPI, Django, Flask, Next.js, React, PostgreSQL, MongoDB, Redis, Docker, AWS, and Google Cloud. • Existing-Code Rescue & Production Deployment I can audit, repair, extend, and deploy existing Python applications or AI-generated projects created with Replit, Cursor, Codex, Claude Code, or similar tools. TYPICAL PROJECTS • AI research, lead qualification, and data-enrichment agents • RAG chatbots and internal knowledge assistants • PDF, report, invoice, and CV extraction systems • Price, product, property, and opportunity-monitoring bots • Browser automation with alerts and scheduled processing • Large-scale web crawlers and ML-ready datasets • API integrations, internal tools, dashboards, and SaaS MVPs • Reliability improvements for Python, Playwright, and LLM applications WHAT YOU CAN EXPECT • Clear requirements and practical architecture • Clean, tested, documented, and maintainable source code • Validation, retries, logging, monitoring, and error handling • Secure deployment with controlled LLM and API costs • Transparent progress updates and complete handover • Full ownership of your source code and data My advantage is the combination of deep web-data engineering experience and modern AI automation. I know where an LLM creates real value and where deterministic rules, validation, or human review are safer and more reliable. Send me your workflow, current code, or sample input and expected output. I will identify the main technical risks and recommend the simplest reliable path from idea to production.

I want to understand why it works, where it breaks, and how reliably it performs in the real world. Whether I’m working on OCR, Document AI, RAG, LLM applications, or AI agents, I approach problems through experiments, evaluation, error analysis, and measurable results not assumptions. I’ll show you what I tested, what the data revealed, what didn’t work, and what I changed because of it. So you’re not just getting a polished demo you’re getting a solution that has been tested, understood, and improved with evidence. My goal is simple: solve the problem properly, make the system measurable, and leave you with something you can actually trust. Tell me what documents or data you’re working with or where your chatbot is hallucinating. I’ll tell you exactly how I’d approach fixing it.

Most AI tools fail on specialized documents. CAD drawings, legal briefs, historical archives, medical forms. I build custom intelligent document processing (IDP) pipelines that actually work on your specific document type, at scale. I turn messy, unstructured documents into structured, queryable data. EOBs, legal contracts, construction plan sets, invoices, medical records, architectural drawings. If your team is drowning in PDFs that need extraction, classification, or decision support, that is what I build. I personally architect and deliver every pipeline. My Upwork track record: → Healthcare EOB extraction: OCR pipeline pulling line-item claim data from Explanation of Benefits documents across dozens of payer formats. Structured output validated against schema, ready for downstream billing systems. → Historical corpus processing at scale: Extraction pipeline over 27,000 corporate annual reports (1900-1945) for an academic researcher. Document preprocessing, OCR, structured field extraction, delivered as validated CSV output across production milestones. → Construction and architectural document intelligence: LLM-powered pipelines that read plan sets, spec books, CAD drawing PDFs, and submittal packages. I understand CSI divisions, RFI workflows, and quantity extraction from drawing sets, not just the model layer on top. → Legal contract Q&A (RAG): Retrieval-augmented generation system for querying contract clauses, obligations, and compliance terms across multi-document sets. → Google Document AI integration: 200+ hours billed building production extraction workflows on the Google Document AI platform. → Invoice OCR automation, translation document pipelines, patient document processing: repeat delivery across document types and industries. My stack: Python, Google Document AI, Mistral OCR, PaddleOCR, Tesseract, LangChain, OpenAI API, Gemini, DeepSeek, spaCy, vector databases (Pinecone, Weaviate, pgvector), PostgreSQL. End-to-end: ingestion, preprocessing, OCR, extraction, validation, structured output, API delivery. 100% Job Success. Top Rated. Every project ships to production. Send me a sample document and I will tell you exactly how I would approach it.
