Marcin Retajczyk

I design cloud and AI architectures for public-sector and enterprise customers. I lead discovery sessions, advise on infrastructure and service consumption, and build proof-of-concept solutions with Python, OCI Generative AI, Enterprise AI, and AI Vector Search. I develop RAG platforms, chatbots, n8n automations, and multi-step agentic workflows using Oracle AI Private Agent Factory and OCI Generative AI Agents. I also represent Oracle at AI Summit Poland, the British Embassy in Warsaw, and meetings with Polish military-sector organizations.

At Intel, I developed and integrated a multi-workload benchmarking platform. I later contributed to Intel Developer Cloud. I used Python, Java, Go, and Groovy for development, and Ansible, Jenkins, Docker, and AWS for automation and cloud delivery. My work included complexity analysis, API performance improvements, query and resource optimization, service integration, and platform reliability.

At IBM Poland, I worked in an agile student team on introductory cloud and infrastructure tasks. I completed training in Google Cloud Platform and cloud fundamentals. Practical work included basic virtual-machine deployment, virtual cloud networking, and team-based delivery.
