Certifications [ 02 ]

2026

Azure AI Cloud Developer Associate (AI-200)

Microsoft

Certification focused on the development, integration, and deployment of artificial intelligence solutions using Azure AI Foundry and services for compute, storage, messaging, security, and monitoring.

Main Project

Developed a RAG-based chatbot to answer questions about the company’s IT systems. Technical documentation was processed to extract relevant information, structure it as JSON, and generate embeddings stored in Azure Database for PostgreSQL. For each query, a Python Azure Function generates an embedding of the question, performs a vector similarity search, and retrieves the content associated with the results. That content is then provided as context to a language model integrated through Azure AI Foundry, which generates the response.
