AI for existing systems
I build AI agents and RAG pipelines for systems companies already use. I connect models to documents, databases and the team's existing tools.
I work on search, document processing and operational automation. AI should remove manual steps and shorten work, not add another dashboard.
When needed, I also build FastAPI APIs, integrations and Nuxt interfaces, taking the solution from prototype to production.
