WORKING INTEGRATION / XDATASYS.COM
Ask the AI about my work.
Built an AI assistant for this portfolio and connected it to my own LLM infrastructure. It answers questions about my experience and projects, with links to the relevant case studies.
- Public portfolio knowledge
- Conversation history
- RU · EN · DE · UA
Example question“What has Maksym automated in his projects?”
How the integration works
- Website
A visitor asks a question.
