About Me
I'm Alexandre Fernandes, a Computer Engineering student in my final semester at ESTGV, Portugal, currently completing my thesis internship focused on AI-powered agricultural systems.
I specialize in building full-stack applications with modern frameworks and integrating AI/ML solutions (LLMs, NLP, RAG) into real-world products. I'm actively preparing for relocation to Germany and seeking opportunities in AI, Automation, and Software Engineering.
