The Book of Short Courses of the Congress on Systems and Computing Development – CODEC 2025, held in Piripiri, Piauí, and organized by the Federal Institute of Piauí (IFPI), compiles the extended versions of the short courses presented during the event. The volume encompasses contemporary and practice-oriented topics that reflect the current challenges and innovations in the fields of computing, software engineering, and systems development. The opening chapter, “Building Scalable APIs with Flask, Firestore, and Render”, presents a comprehensive approach to the design and deployment of RESTful APIs using Python, emphasizing modular architectures, NoSQL data persistence, and continuous cloud deployment practices. The second chapter, “Developing a Multi-Agent System for Scientific Research with LangGraph”, discusses the application of artificial intelligence through intelligent agents and multi-agent frameworks to automate scientific data retrieval, validation, and analysis processes. The third chapter, “Exploring End-to-End Testing with Playwright: An Invitation to Quality Automation”, addresses the theoretical and practical foundations of software testing, highlighting automation strategies that ensure quality assurance and reliability in web applications. The fourth chapter, “Embedded Systems: A Practical Approach with BitDogLab”, introduces the fundamentals of embedded systems through experimental activities that integrate hardware and software concepts in an accessible educational context. Finally, “Introduction to Git and GitHub: Version Control in Practice” provides a structured overview of version control principles and collaborative development workflows, focusing on the practical use of Git and GitHub in academic and professional environments. Collectively, the chapters illustrate the interdisciplinary nature of computing and software development. The CODEC 2025 short course collection embodies the event’s mission to promote the integration of teaching, research, and professional practice, fostering active learning, collaboration, and technological innovation.
