About Alejandro

I am a Cloud Platform Engineer and Cybersecurity Architect with deep expertise designing and operating secure, scalable, and resilient infrastructure across cloud and on-premise environments. I combine strong architectural skills with hands-on experience in reliability engineering, cybersecurity, automation, and cost governance.


My background spans large enterprises and global tech startups, giving me the ability to work effectively in distributed teams, influence technical direction, and collaborate across engineering, product, and leadership. I maintain a strong focus on communication, alignment, and technical excellence.

Core strengths include:

  • Cloud Platform Engineering
Architecture and deployment of cloud-native systems that are secure, scalable, and aligned with business and compliance requirements.
  • Cybersecurity Architecture
End-to-end security design covering vulnerability management, secure deployments, supply-chain hardening, and in-depth infrastructure risk analysis.
  • Hybrid & On-Premise Architectures
Modernization and optimization of legacy, hybrid, and datacenter environments with an emphasis on performance, security, and reliability.
  • Cloud-Native SRE
Implementation of observability, automation, reliability best practices, and operational excellence for production workloads.
  • Cost Optimization
Systematic reduction of infrastructure spend through architectural improvements, resource efficiency, and continuous cost analysis.



I thrive in complex environments where reliability, security, and scalability are critical. Open to new opportunities that benefit from solid engineering judgment, secure-by-design thinking, and platform-level ownership.
