Linux & Docker audit
Inventory, exposure, logs, resources, backups, and a prioritized correction plan.
Open to scoped technical work · Argentina
Infrastructure you can understand, measure, and repair.
I'm Lautaro, a SysAdmin and Backend Developer. I help small teams stabilize Linux/Docker systems, verify backups, improve observability, and automate processes without starting with an impossible-to-scope project.

How I can help
Concrete services, not an endless technology list.
Every engagement starts with a stage that can be understood, priced, and verified before the scope grows.
Backups & hardening
Scoped changes, encrypted backups, recovery testing, and rollback documentation.
Monitoring & incidents
Useful alerts, operational dashboards, and troubleshooting for services that need to stay up.
n8n & API automation
A measurable first automation across APIs, Sheets, Notion, Telegram, or existing systems.
How I work
Less heroics. More traceability.
A solution is only good if it remains easy to operate after the handoff.
Understand
What is happening today, what cannot break, and how the result will be validated.
Scope
A small first stage with deliverables, boundaries, and acceptance criteria.
Solve
Observable changes, reversible where appropriate, backed by evidence.
Handoff
Documentation, open items, and a clear way to operate afterwards.

Production reliability improved
Monitoring Agent Migration at Scale
A fleet of production Linux servers was running a monitoring agent version approaching end of support. The migration covered messaging, DRM, licensing and backend services.
impact
Approximately 50 hosts were migrated by Lautaro. No rollback was required, and no host lost monitoring visibility for more than approximately two minutes.

Operational cost improved
Temporary Capacity Doubling for a High-Traffic Load Test
A UAT environment needed to run a representative stress test before a high-traffic event, but its standard capacity was not enough to model the expected load.
impact
The stress test passed without issues. The temporary capacity increase provided a representative test profile without leaving permanent overprovisioning afterward.

Incident stabilized
RabbitMQ Backlog and Controlled Message Flush
Consumers connected to a production RabbitMQ cluster were not processing messages fast enough. The backlog grew and the affected node became stuck under resource pressure.
impact
The manual flush discarded queued messages but prevented the stuck node from continuing toward a more severe resource-exhaustion condition. The exact recovery time is not documented.

Have a concrete problem?
Let's understand it before trying to sell you a huge system.
Tell me what is failing, what you want to improve, and what cannot break. I will reply with an initial read and a proposed first stage.
