You will get Claude API / OpenAI Integration: Custom AI Into Your Existing System
Project details
You need AI to do something specific inside your workflow, extract data from documents, classify inputs, generate structured
output, or make decisions based on business logic.
I integrate Claude API or OpenAI into your existing system so it does exactly that. Reliably, not just in demos.
I've built AI integrations for document processing, product description scoring, visual product search, and sales intelligence
pipelines. All in production environments for real B2B clients.
What makes this different: I design for production, not demos.
That means prompt versioning, fallback logic, output validation,
and token cost optimization before anything goes live.
You get working AI integration, prompt docs you can maintain
yourself, and someone who understands the business context
behind the technical requirement.

About Marek
AI Automation Expert Make Claude API Workflow Architect
Liberec, Czech Republic - 5:06 am local time
With 25+ years in B2B and 3+ years deep in AI implementation, I design and build automation workflows across Make, n8n, Claude API, and OpenAI. From simple document processing to multi-step agentic pipelines.
What I do:
→ Make & n8n workflow automation (CRM, ERP, e-commerce, SaaS integrations)
→ Claude API / OpenAI custom integrations (document processing, classification, extraction)
→ AI audit & reliability review. I diagnose broken or underperforming AI systems, and tell you exactly what to fix
→ Fractional Head of AI. for companies that need strategic AI leadership without a full-time hire
I work primarily with European SMEs and B2B SaaS companies, with deep familiarity in European markets, but I take projects globally.
I don't build hype. I build systems that work on Monday morning.
Languages: English (professional), Czech (native)
Steps for completing your project
After purchasing the project, send requirements so Marek can start the project.
Delivery time starts when Marek receives requirements from you.
Marek works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery & prompt design
I review your input data and design the prompt architecture — including output format, edge case handling, and confidence thresholds before any code is written.
Integration build & testing
I build the Claude/OpenAI integration into your workflow, test with real data, and validate output quality against your acceptance criteria.
