You will get AI Document Processing System (OCR + Data Extraction)
Project details
I build AI-powered document processing systems that automatically extract, classify, validate, and structure information from business documents.
These solutions are designed to eliminate manual data entry, reduce processing time, and improve accuracy across document-heavy workflows.
The solution can combine OCR, AI-powered extraction, document classification, validation rules, and structured data output, allowing your team to work with clean and actionable information instead of raw documents.
Each system is built for production use and can integrate with your existing databases, APIs, CRMs, ERP platforms, or internal workflows.
What's included:
• OCR and document parsing pipeline
• AI-powered data extraction and classification
• Structured output (JSON, CSV, database-ready data)
• Validation and processing workflows
• Integration with existing systems and APIs
• Production-ready deployment
• Full source code and technical documentation
Key technologies: Document AI, OCR, Tesseract, OpenCV, Python, AI Classification, Data Extraction, Machine Learning, PostgreSQL, API Integration, Docker, Cloud Deployment.

About Vira
LLM Agent Engineer | RAG & Multi-Agent Systems | Node.js, PHP/Laravel
Chernivtsi, Ukraine - 2:11 am local time
📦 What I deliver:
→ Multi-agent orchestration (LangChain, CrewAI, agent collaboration)
→ RAG pipelines with vector databases (pgvector, Pinecone, FAISS)
→ Document AI (extract data, fill forms, structured outputs)
→ Conversational assistants (tax, legal, internal tools)
→ LLM + ML combination (classification, analysis, predictions when needed)
→ Integration into existing apps (Node.js, Laravel, Python backend)
→ Full-stack implementation (backend, frontend, API, deployment)
💼 15+ years full-stack experience - Node.js, PHP/Laravel, Python, React, Vue.js, PostgreSQL, Docker, AWS. In the last few years, most of my work is AI built into real products: SaaS platforms, enterprise tools, internal automation.
📌 Recent projects:
1. Multi-agent document processor (Tech Lead)
→ Turns contracts into structured estimates through chat-based refinement
→ LangChain + GPT-4 + pgvector + multi-agent orchestration
→ Node.js backend, Vue.js frontend, Docker deployment
2. Conversational tax assistant
→ RAG system with vector DB for domain-specific knowledge
→ Extracts data from documents, fills forms, handles submission end-to-end
→ Python backend, React frontend, PostgreSQL
3. Market research AI service
→ LLM for automated report generation
→ ML (scikit-learn, pandas) for statistical analysis: crosstabs, conjoint, MaxDiff, sentiment
→ Laravel + Node.js + Vue.js, mobile apps with Flutter, payments, real-time sync
4. Video production AI pipeline
→ Multi-service platform for video processing automation
→ AI agents for transcription, summarization, metadata extraction
→ Python, FastAPI, AWS, Docker
🛠 Services I offer:
→ Build LLM agent from scratch (multi-agent, RAG, custom workflows)
→ Add AI to existing Laravel/Node.js/Python app
→ Document processing automation (extract → classify → output)
→ Conversational assistant for internal tools or customer support
→ LLM + ML combination for analytics/classification
→ API integration (OpenAI, Anthropic, Gemini, custom models)
→ Full-stack development (backend, frontend, deployment)
🔧 I can work on:
→ AI layer only (agents, RAG, prompts)
→ Backend only (Node.js, PHP, Python)
→ Frontend only (React, Vue, Angular)
→ Full stack (all of it)
→ Technical leadership (architecture, team coordination)
