Back to original languageAbout Oguzhan
I develop production-ready AI systems for companies that automate document- and audit-intensive processes — LLM applications, RAG pipelines, and multi-agent workflows. From architecture to implementation to validation, all from a single source.
My differentiator: I build AI not just to run, but to be enterprise- and compliance-ready. With my background in Security & Risk (M.Sc. Cyber Security, ISO 27001, GDPR, Responsible AI), I create solutions that also hold up in regulated environments — where many prototypes fail.
How I support clients:
• LLM & RAG Systems: intelligent document analysis, knowledge retrieval, Q&A over proprietary data
• Multi-Agent Automation of multi-stage processes (import, verification, calculation, reporting)
• AI Process Automation: accelerating manual, document-heavy workflows
• AI Integration into Backend (Python, FastAPI, AWS Bedrock) incl. QA & Validation
Proof: At an industrial insurance company, I brought a multi-agent prototype from idea to pilot operation — the productive scaling was subsequently handled by the AWS Research Team.
