Fabio developed ARM64 Docker Compose support for the citrineos/citrineos-core repository, focusing on improving cross-architecture reliability and developer onboarding. He introduced a dedicated docker-compose.arm64.yml file with platform-specific images for RabbitMQ, PostGIS, MinIO, and Hasura, ensuring Apple Silicon compatibility. To address startup sequencing issues, Fabio implemented a health check in the citrine service so that the graphql-engine launches only after citrine is healthy, reducing startup failures. He updated documentation and dependencies to reflect these changes. This work, using DevOps practices, Docker, and Node.js, established a more robust foundation for ARM64 deployment and streamlined the onboarding process.
