Faced with a 20-year-old legacy system with 4 million lines of code at the core of OBI’s organization, Sergio took the initiative to transform it into a product-oriented, modular architecture. This talk shares practical best practices and hard-earned insights, covering step by step how to define a clear vision and set achievable goals for legacy transformation, apply Domain-Driven Design (DDD) for effective domain and architecture analysis, secure leadership buy-in for long-term modernization investments, engage a large team and various stakeholders in the transformation journey, and prioritize and strategically phase the modularization process.
Legacy systems, often seen as a burden, hold immense potential. Sergio will demonstrate how to unlock this potential and turn legacy code into valuable, adaptable products.
