About Alejandro

More than 6 years implementing and optimizing cloud infrastructure on AWS. I help companies deploy with confidence: infrastructure as code, CI/CD pipelines, and complete observability, with security as a requirement, not a patch.
What I do well:
- Infrastructure as Code: Terraform daily in production environments; also Puppet for configuration management. Linux and Windows.
- CI/CD and zero-downtime deployments: pipelines with GitHub Actions and Bitbucket Pipelines; blue-green deployments in ECS with CodeDeploy/CodeBuild ensuring zero downtime.
- Observability: Prometheus, Telegraf, and Grafana from scratch to production, plus OpenTelemetry for distributed tracing in complex environments.
- APIs and Security: API Gateway with mutualTLS, proxy management, and API integration with a focus on security and scalability.
- AI on AWS: agents with Amazon Bedrock (Bedrock Agents / AgentCore).
- Automation: Python, GoLang, Node.js, and Bash to eliminate manual work — scrapers, integrations, alerts, scheduled tasks.
Availability: one-off projects or recurring support of 1-3 days/month. I respond in under 24 hours.
