About

I help engineering teams build real AI systems — not just understand them in theory. For the past 2+ years, I have delivered corporate AI/ML training programs through Educate360 for large-scale U.S. engineering organizations. My sessions consistently receive 5-star reviews from engineering teams across industries. My courses are practical, notebook-based, and designed for teams that need to understand how modern AI systems actually work — not just hear about them in slides. I teach and build around the full AI learning path: • Python for Data Science • Python for Machine Learning • Deep Learning • OpenAI API • RAG pipelines • Agentic AI systems • Production-minded AI workflows My teaching style combines systems thinking, real code, and engineering judgment. I focus on helping teams understand the "why" behind the architecture: how data becomes features, how models become decisions, how retrieval becomes memory, and how agents become useful software systems. Academically, I hold a PhD in Systems Engineering from Universidad Nacional Federico Villarreal, an MS in Software Engineering from Universidad Ricardo Palma, and a BS in Electrical Engineering from Drexel University. I also teach graduate-level Machine Learning and Deep Learning at UNMSM and UAP. My delivery model is 100% remote via Zoom, available globally. I am especially useful for teams that want practical AI adoption without hype: clear explanations, working notebooks, production mindset, and a path from fundamentals to real AI systems.
