Evolução da plataforma SIGA: implementação de backend em microsserviços e suporte a operação offline

Abstract

Digital transformation in agribusiness faces significant barriers due to inadequate network infrastructure in Brazilian rural areas. This scenario compromises the reliability of traditional inspection systems, generating risks of data loss and fraud in technical reports. Addressing this challenge, this work presents the architectural evolution of the SIGA platform (Sistema de Inspeção Geográfica Agrícola), elevating it from a user interface prototype to a robust and resilient distributed system. The adopted methodology involved implementing a microservices backend using Java and Spring Boot, orchestrated by a reactive API Gateway to handle high synchronization loads (thundering herd). On the frontend, the application was restructured as an Offline-First Progressive Web App (PWA), leveraging Service Workers and IndexedDB to ensure local persistence and automatic form submission via Background Sync. Stress tests and disconnection scenarios validated the architecture’s effectiveness, confirming data transactional integrity and geolocation security even without internet access. The proposed solution enables SIGA to operate as a reliable field inspection tool, eliminating dependence on manual processes and ensuring business continuity regardless of network stability
