Ioana Alexandru User

I’m a Computer Science graduate and self-employed software developer, focused on AI/ML engineering and cybersecurity. I build AI systems that are both performant and secure, bridging model capabilities with real-world safety and testing.

In production projects, I’ve architected LLM solutions like an AI Sales Chatbot for a travel agency—grounding answers with a RAG pipeline using real-time site search results. I also develop agentic workflows and multi-step reasoning systems, including AI agents built with Azure AI Foundry that use tool- and context-aware orchestration patterns.

On the security side, I conduct vulnerability assessments, authorized penetration testing, and red-teaming workflows. I’ve used Burp Suite and OWASP ZAP for thorough testing and reporting, and I explicitly address LLM-specific attack surfaces like prompt injection, RAG data leakage, and context manipulation.

I’m an active mentor and continuous learner who likes shipping with structure, documentation, and measurable outcomes. From test automation and protocol analysis to LLM engineering, I bring a disciplined mindset that helps teams move faster—without compromising security.
