Yannick Lemin

With over 24 years of software engineering experience and a decade as a freelance architect, I’ve built a career around adaptability, deep curiosity, and a strong love for solving complex technical problems. From crafting cross-platform C++ applications in the early 2000s to leading backend transformations in Kotlin and Spring Boot today, my journey has spanned a variety of industries, stacks, and challenges. For more than 12 years, I specialized in Android development, shaping high-traffic mobile experiences and architecting clean, maintainable systems. In recent years, I’ve shifted my focus toward backend development and cloud infrastructure—embracing microservices, DevOps, and platform engineering at scale. Now, I’m looking toward the next frontier: AI integration. I’m actively training myself in the field of large language models (LLMs), with a growing focus on Retrieval-Augmented Generation (RAG), fine-tuning pre-trained models, and the practical challenges of embedding intelligence into software systems. While I may not yet have commercial AI experience, I bring a strong foundation in architecture, backend systems, and real-world engineering that I believe translates exceptionally well to the world of applied AI. In parallel, I’m exploring the landscape of AI tooling, with a keen interest in comparing Python-based solutions—the current industry standard—with emerging JVM-based options like LangChain4J and Spring AI. As someone with deep roots in the JVM world, I’m particularly motivated to bridge the gap between traditional enterprise stacks and modern AI capabilities. I’m eager to collaborate on projects that combine solid engineering with intelligent behaviors—whether it’s enhancing user experiences with natural language interfaces, building smart agents, or embedding decision-making into cloud-native systems. Let’s build the future—one intelligent system at a time.
