Argentina · SysAdmin & Backend Developer

Backend systems.
Linux operations.
Cloud troubleshooting.

I build backend services and keep production infrastructure understandable, observable and recoverable. My day-to-day connects application code to Linux, Kubernetes, networking, CI/CD and the systems behind real production work.

A portfolio shaped like the systems behind it.

Synthetic stream — but the shape is honest: this is what production looks like once you've earned the right to read it calmly.

Value

Systems that are easier to deploy, observe, and repair.

My work connects backend development with infrastructure operations: service design, automation, observability, networking, and incident response.

module_01

Backend services with operational reality in mind

Authentication, role-based access, business logic, and the observability hooks needed to understand what the service is actually doing under production pressure.

module_02

Production infrastructure that can be repaired

Linux, Kubernetes clusters, Helm charts, CI/CD pipelines and cloud environments — kept in a shape where deployments and incidents both have a clear procedure.

module_03

Debugging across layers

Network, system, runtime, application. Logs, metrics, packet path, NAT, VPN, workers, cronjobs — read together instead of one at a time.

Commands I actually use

Operational evidence, not a cheat sheet.

The shell I live in, grouped by domain. Real commands from real production work — Kubernetes, Linux, networking, CI/CD, Docker, Terraform, debugging.
