Presentation
Large Language Models (LLMs) are increasingly used in real-world applications but designing reliable and scalable systems remains challenging. This 1-day workshop focuses on the practical development of LLM-based applications using Python. Participants explore key design patterns such as structured outputs, retrieval-augmented generation (RAG), tool integration, and agentic workflows, while also addressing engineering considerations such as evaluation, robustness, and cost control.
Main objectives
- Understand the architectural components of modern LLM-based systems (structured output, APIs, context management, tool integration, …)
- Implement structured outputs and simple agentic mechanisms in a real use case
- Evaluate LLM system performance using appropriate metrics and testing strategies
- Identify and mitigate common failure modes (hallucinations, prompt brittleness, cost inefficiencies)
- Acquire practical guidelines for moving from prototype to production-ready systems
Topics covered
LLMs, history, terminology, and concepts / Structured outputs and tool calling – enabling LLMs to interact with external systems, extract structured data, and follow precise formats / Advanced techniques & Agent design patterns – RAG, reasoning loops, multi-agent systems, routing strategies workflows / Production considerations – evaluation frameworks, cost management, debugging strategies, and fail-safe mechanisms.
Details
Prerequisites

Valerio started his career working for 7 years as a particle-physics researcher at CERN. In 2016, he moved to consulting, applying data science in several industries. First, he joined the Quant team of Ernst & Young in Geneva. Later, he created his own company, SamurAI sàrl, providing consulting services for his clients. He also has a passion for teaching very complex subjects in simple terms. That is why he particularly enjoys offering training programs to private companies and universities. Valerio joined the SDSC in May 2022 as a Principal Data Scientist with the mission of accompanying industrial partners and other institutions through their data science journey.
Sean obtained his PhD in Telecommunications Engineering from Dublin City University in 2001. Since then he has worked in large industry and startup contexts but has spent most of his time working in academic research labs with a strong applied focus spanning both Ireland and Switzerland. Sean has experience with all aspects of the research project lifecycle, ranging from project inception to proposal stage to project execution and reporting. Having a keen interest in technology trends and evolution, he strives to maintain a hands on approach with practical experience with key technologies in the rapidly changing cloud and analytics technology landscape. Sean works on the Renku Infrastrucuture team, leveraging his experience with modern cloud technologies, helping to make Renku easy to deploy and manage.
Luis is originally from Spain, where he completed his bachelor's studies in Electrical engineering, and the Ms.C. on signal theory and communications, both at the University of Seville. During his Ph.D. he started focusing on machine learning methods, more specifically message passing techniques for channel coding, and Bayesian methods for channel equalization. He carried it out between the University of Seville and the University Carlos III in Madrid, also spending some time at the EPFL, Switzerland, and Bell Labs, USA, where he worked on advanced techniques for optical channel coding. When he completed his Ph.D. in 2013, he moved to the Luxembourg Center on Systems Biomedicine, where he switched his interest to neuroscience, neuroimaging, life sciences, etc., and the application of machine learning techniques to these fields. During his 4 and a half years there as a Postdoc, he worked on many different problems as a data scientist, encompassing topics such as microscopy image analysis, neuroimaging, single-cell gene expression analysis, etc. He joined the SDSC in April 2018. As Lead Data Scientist, Luis coordinates projects in various domains. Several projects focus on the application of natural language processing and knowledge graphs to the study of different phenomena in social and political sciences. In the domains of architecture and engineering, Luis is responsible for projects centered on the application of novel generative methods to parametric modeling. Finally, Luis also coordinates different projects in robotics, ranging from collaborative robotic construction to deformable object manipulation.
