About
Howdy, I am Yann, an Independent AI Researcher and Solutions Architect with 8+ years of experience designing, building, and scaling large-scale data and AI/ML systems across Apple, Google, and fast-growing technology environments. My work sits at the intersection of AI systems architecture, large-scale data pipelines, and independent research into how intelligent systems are trained, evaluated, and deployed in real-world contexts. I focus on system-level thinking; how data, models, infrastructure, and human constraints interact at scale beyond isolated model performance. At Apple, I contributed to improving AI/ML training pipelines supporting 50M+ Siri users, enhancing dataset accuracy, optimizing multilingual workflows, and building analytics frameworks that increased error-detection efficiency by 35%. At Google, I engineered data pipelines to improve Knowledge Graph accuracy and Search AI relevance, supporting systems used by hundreds of millions of users daily. Alongside industry work, I pursue independent AI research focused on scalable learning systems, evaluation frameworks, data integrity, and emerging post-LLM architectures. My research interests emphasize robustness, alignment with real-world constraints, and system-level intelligence, informed by hands-on experience operating AI at production scale. Technically, I bring deep experience in Python, SQL, ETL/ELT, distributed systems, data modeling, ML evaluation, and cloud-native architectures, paired with strong cross-functional collaboration across engineering, product, and executive teams. I regularly lead POCs, design end-to-end systems, and translate complex technical ideas into clear, actionable decisions. I’m driven by building scalable, durable AI systems and contributing original thinking to how intelligent infrastructure should evolve; practically, responsibly, and at scale.

San Juan
SanJuan AI: Puerto Rico’s Local AI SanJuan AI is building the first Local AI model for Puerto Rico: an intelligent system designed to understand, serve, and evolve with the island. More than a chatbot, SanJuan AI is a locally grounded AI deployment trained on Puerto Rico’s culture, language, economy, and real-world needs. It represents a new paradigm: AI that belongs to a place and its people, not a generic global model. The SanJuan AI system is being developed as a living local intelligence layer; enabling residents, businesses, and institutions to access trusted information, automate workflows, and interact with AI that understands Puerto Rico contextually, not abstractly. SanJuan AI enables: • Local-context AI assistance for businesses, tourism, culture, and daily life • Embedded tools for navigation, services, permits, and community knowledge • A foundation for future Local AI deployments beyond Puerto Rico Alongside the platform, SanJuan AI also provides AI consulting, training, and certification, helping entrepreneurs, professionals, and organizations adopt AI responsibly while the Local AI system evolves. Our mission: To establish Puerto Rico as a pioneer of Local AI where intelligence is rooted, contextual, and built for the people it serves.

Mandela Washington Fellowship - Alumnus
The Mandela Washington Fellowship for Young African Leaders is the flagship program of the U.S. Government’s Young African Leaders Initiative (YALI), administered through the U.S. Department of State. Since its creation in 2014, the fellowship has brought together nearly 7,200 of Africa’s brightest minds from every country in Sub-Saharan Africa. Each year, exceptional leaders between the ages of 25 and 35, who have already demonstrated outstanding achievement in driving innovation, building communities, and advancing positive change, are competitively selected to participate. The fellowship provides intensive academic and leadership training at leading U.S. universities, professional development opportunities, high-level networking, and direct engagement with American and African leaders. Fellows gain world-class skills, build cross-continental collaborations, and return home with the tools to strengthen democracy, foster inclusive economic growth, and improve the lives of millions across Africa. Being awarded this prestigious opportunity by the U.S. Department of State has been nothing short of life-changing. It represents not only international recognition of leadership and impact, but also an investment in Africa’s next generation of changemakers. This fellowship has expanded my vision, sharpened my leadership capacity, and connected me to a global network of innovators who are reimagining Africa’s future. The Mandela Washington Fellowship is more than a program, it is a gateway to excellence, empowerment, and lifelong transformation.
