Retrofitting Intelligence into Legacy Systems
Many established businesses in Croatia and the EU are sitting on goldmines of data locked in aging software. We build intelligent middleware layers that act as a bridge. Using n8n for orchestration, we connect your legacy SQL databases or internal tools with modern AI engines like GPT or Claude.
This process—often called 'AI Retrofitting'—allows you to add advanced features like natural language querying or automated document summarization directly into your existing dashboard, avoiding the high cost and risk of a full system overhaul.
Advanced Orchestration with LangChain
To move beyond simple API calls, we utilize LangChain. This framework allows us to create 'chains' of thought, where the AI can reason, use tools, and access external data before providing an answer.
By leveraging LangChain, we build autonomous agents that can:
- Analyze complex documents: Extracting structured data from unstructured PDFs.
- Perform Multi-Step Tasks: Checking stock levels in your ERP before drafting a customer email.
- Maintain Context: Ensuring the AI remembers previous interactions and business-specific rules across your entire stack.
High-Value AI Use Cases
We implement micro-services that solve specific, expensive operational bottlenecks:
- Automated OCR & Data Extraction: Converting thousands of invoices or contracts into structured database rows instantly.
- Sentiment-Driven Workflows: Automatically flagging urgent customer complaints in Slack for immediate intervention.
- Predictive Maintenance & Vision: Integrating computer vision to detect anomalies in production or logistics flows.
RAG Architecture & Data Privacy
Data privacy is paramount. We implement Retrieval-Augmented Generation (RAG) to ensure the AI only uses your facts and never leaks data to public models.
By utilizing Vector Databases (like Pinecone or Weaviate), we give the AI a private 'knowledge base' of your business. This eliminates hallucinations and ensures that every AI-generated insight is grounded in your proprietary data, fully compliant with GDPR standards and your internal security policies.
