Nuestro mundo funciona con TI construida en los años 80 y 90 por ingenieros que ahora se están jubilando. Esto se está volviendo muy preocupante para las corporaciones que tienen sistemas críticos funcionando en código legado que solo un puñado de personas aún entiende.

Ahí es donde llega GenAI. Con sus habilidades de transpilación casi mágicas, es la innovación que se necesitaba para iniciar las modernizaciones de legado que se habían pospuesto durante demasiado tiempo.

Habiendo trabajado en modernizaciones críticas durante más de 15 años, aproveché la oportunidad para experimentar cómo los LLMs pueden acelerar proyectos de migración complejos.

Compartiré la experiencia concreta que hemos acumulado en una amplia gama de stacks (Swift->React-Native, Eclipse RCP -> Spring Boot, Java 1.6 Spring -> Java 21 Spring Boot, PHP ZF1 -> Symfony 7), cubriendo tanto las buenas sorpresas como las limitaciones que descubrimos, y compartiré nuestro manual actual para aprovechar al máximo la AI al migrar un sistema legado.

This talk has been presented at TechLead Conf London 2025: Adopting AI in Orgs Edition, check out the latest edition of this Tech Conference.

This Talk introduces the Epic Stack, a project starter and reference for modern web development. It emphasizes that the choice of tools is not as important as we think and that any tool can be fine. The Epic Stack aims to provide a limited set of services and common use cases, with a focus on adaptability and ease of swapping out tools. It incorporates technologies like Remix, React, Fly to I.O, Grafana, and Sentry. The Epic Web Dev offers free materials and workshops to gain a solid understanding of the Epic Stack.
