Reliable, resilient, automated, monitored.
mig5 helps teams build and run Linux infrastructure that's secure, defined as code, and easy to audit.
What does mig5 do?
mig5 works on Linux infrastructure: configuration management, security hardening, monitoring, and backups.
Fully remote and operating as your go-to infra person or augmenting existing in-house teams - often providing the "night shift” for teams outside UTC+10/11.
Infrastructure that stays up.
Configuration & change management
Infrastructure as code, automated config, backups, and monitoring for repeatability and auditability.
CI/CD pipelines
Build pipelines that test, ship, migrate, and roll back safely - with less manual button pushing.
Security hardening & compliance
Hardening, firewalling, encryption, MFA/OAuth, logging, and systems designed to meet ISO27001 goals.
High availability & disaster recovery
Design for failure: redundancy, replication, load balancing, and rehearsed recovery plans.
AI augmentation (self-hosted)
Open-source AI where third-party tooling isn't safe or viable: analysis and RAG over your own data.
Open source & social impact
Privacy, equality, and a bias toward open standards and community-driven tooling.
Tools I build (and use in real work)
Melbourne-based, working remotely
mig5 is a Melbourne-based sysadmin consultancy run by Miguel Jacq (he/him), working in this field since 2007. Miguel is an Australian and French citizen who likes the kind of problems where you have to figure out what's actually going on before you can fix anything.
