Freelancer profile translated to English.

Description

I develop automations with AI for companies that want to save time, reduce manual work, and bring artificial intelligence to real business processes.

I specialize in AI agents, RAG, Python, Azure, SQL, and APIs, building production-ready solutions: internal assistants, document automation, intelligent search over documentation and databases, and integrations with existing tools and systems.

I usually fit particularly well in projects involving:

process automation

AI agents

RAG over documentation and databases

document workflows

cloud integrations and deployment on Azure

APIs and backend to support AI solutions

My added value is not just implementation, but understanding the business case, choosing the most useful approach, and building robust, maintainable, and results-oriented solutions.
