Linux infrastructure for organisations where security, privacy, and reliability matter.
I'm Miguel Jacq. I help small and specialist teams run systems safely: untangling inherited Linux estates, automating change, hardening security, improving monitoring and recovery.
Working on production systems since 2007. Fully remote from Melbourne, Australia.
When I tend to be useful
The technology varies. The recurring theme is infrastructure that matters, has accumulated complexity, and needs experienced hands without a wholesale rewrite.
- Production has become something nobody wants to touch.
- Too much depends on one person's memory or undocumented "tribal knowledge".
- Deployments are manual, fragile, or difficult to roll back.
- Backups exist, but nobody is very confident about restoring them.
- Security or compliance requirements have outgrown the current setup.
- An incident exposed gaps in monitoring, access control, or recovery.
- Sensitive data means the usual SaaS or outsourcing assumptions need more scrutiny.
- A small team needs senior infrastructure depth without another full-time hire.
Make important infrastructure less fragile.
Understand & stabilise
Map inherited systems, find the dangerous assumptions, fix the immediate risks, and make changes safer.
Automate & document
Turn snowflakes and manual procedures into reproducible configuration, pipelines, and playbooks.
Harden & control
Practical hardening, identity, encryption, secrets, logging, patching, and audit-friendly change.
Detect & recover
Monitoring that tells you what matters, backups you can restore, and recovery plans you can actually execute.
Mission matters to me, too.
I particularly value work with organisations concerned with security, privacy, human rights, civil society, public-interest technology, and open source. That isn't a requirement; it's simply where a lot of my work and interests have converged.
I also work with web agencies when the problem is a good fit. The common denominator is taking the systems, the risks, and the people affected by them seriously.
