PROJECT://GREENBOX
GreenBox Infrastructure & Automation Platform
- Design and operate a multi-node Linux infrastructure platform spanning x86_64 and ARM systems, with centralized identity/DNS integration, secure remote connectivity, reverse proxies, service publication, monitoring, backup/recovery, and cross-node administration.
- Build and maintain Python and Bash automation using preflight checks, staged changes, validation, reporting, backup, rollback, and repeatable deployment workflows for infrastructure and self-hosted services.
- Deploy and operate services including Nextcloud, MeshCentral, Frigate, WordPress, notification services, knowledge/documentation systems, and other self-hosted applications across the GreenBox environment.
- Engineer practical solutions across Linux services, networking, remote administration, storage, certificates/TLS, identity, resilience, and distributed troubleshooting rather than relying on one-off manual fixes.
- Develop centralized operations, knowledge, field-computing, and navigation tooling to make a growing multi-node environment easier to manage, document, recover, and use.
- Continuously evolve GreenBox toward stronger infrastructure-as-code, configuration management, CI/CD, cloud integration, and platform-engineering practices while preserving production safety and rollback discipline.
