What I'm looking for

I'm looking for remote opportunities across Europe where I can build and deploy practical LLM, RAG, cloud, and distributed-system applications.

At ARIVERSE, I built AI-powered applications that transform manual business processes into structured digital workflows, including an LLM document-extraction system using Google Gemini, Streamlit, PostgreSQL/Supabase, and Google Cloud Run.

I've also delivered enterprise software, QA, and DevOps work across Java, distributed infrastructure, Docker, Kubernetes, GitLab CI/CD, Jenkins, and Ansible. My background in IoT, embedded systems, data pipelines, and RAG concepts helps me build practical AI applications from backend integration through deployment.
