About Alejandro

IT systems and infrastructure administrator with extensive experience in backup, storage, and business continuity (DR/BCP). I help companies protect their critical data, recover from incidents (failures, ransomware, deletions), and optimize their backup platforms, both on-premise and in the cloud.

I work primarily with Windows/Linux environments, virtualization, and enterprise backup solutions, designing secure, scalable, and auditable architectures. My focus is not only on “making the backup work,” but also on ensuring that restoration is reliable and fast when it is really needed.

Main services:

Design and implementation of backup and disaster recovery strategies

Migration and optimization of on-premise, hybrid, and cloud backups

Backup audits, restore testing, and anti-ransomware plans

Configuration of immutable backups and retention policies

Optimization of cloud storage and backup costs

Support and maintenance of critical infrastructures

How I work:

Clear and direct communication (technical English and Spanish)

Detailed documentation of changes and procedures

Results-oriented and risk reduction

Experience working 100% remotely with international teams

I am looking to collaborate with SMEs, startups, and MSPs that need a reliable professional for one-off projects or recurring support, especially in environments where data loss is not an option.

If you need your backups to really work when it matters most, let's talk.
