What I'm looking for

I’m looking for a role where I can build production AI systems and ship scalable full-stack features—especially document intelligence, RAG workflows, and modern React/Django applications with strong engineering practices.

I’m an AI Engineer and Full-Stack Engineer focused on shipping production-ready AI systems and scalable web applications. I’ve built a multi-step document intelligence pipeline for a German bank, analyzing 400+ page reports and generating structured evaluation summaries using Microsoft Document Intelligence, Python, and LLM workflows.

I also developed an AI-powered product matching engine that converts legacy generalized Fibonacci P93 tender files into structured JSON and recommends matching products using Python, LLM pipelines, and custom scoring logic. For a pharmaceutical company, I built a RAG-based internal knowledge assistant with document ingestion, vector search, automated evaluation pipelines, and a React frontend.

On the engineering side, I’ve delivered end-to-end features across React, Django, Vue.js, Angular, Node.js, and SQL—ranging from real-time document editing, version control, and role-based access management to dynamic tagging systems and responsive UI modernization. I’m comfortable with production workflows, using Docker, AWS, Kubernetes, Git, and CI/CD tooling to keep systems reliable as they grow.
