Hi, I'm Pablo, nice to meet you!

DevOps Manager specialized in designing, deploying, and operating cloud infrastructure for cross-platform applications (web and mobile).

About me

I am a DevOps Manager with hands-on experience building scalable, secure, and automated cloud platforms. My main goal is to help development teams deliver software faster and more reliably by applying DevOps best practices such as Infrastructure as Code, CI/CD, and Cloud Native architectures.

In my free time, I enjoy working on side projects and playing guitar in my Metalcore band, Bloom Court.

What I do as a DevOps Manager

I focus on bridging the gap between development and operations by designing platforms that are:

  • Scalable: able to grow with business needs
  • Reliable: high availability, fault tolerance, and resilience
  • Secure: security by design, least privilege, and compliance
  • Cost-efficient: cloud cost optimization and resource governance

My role combines hands-on technical work with technical leadership, ensuring best practices are adopted across teams.


My main stack

These are the core technologies I use daily to design, deploy, and operate modern cloud infrastructure:

Stack Description
AWS Designing scalable and secure cloud architectures (VPC, EC2, ECS/EKS, RDS, S3, IAM, CloudWatch).
Terraform Infrastructure as Code to create reproducible, version-controlled environments.
Jenkins CI/CD pipeline automation for build, test, and deployment processes.
Docker Application containerization for consistent and portable environments.
Kubernetes Container orchestration and workload management in production.
Git Version control.
Shell Automation through scripting.

Cloud & Infrastructure Architecture

I design and operate cloud-native architectures with a strong emphasis on:

  • Multi-environment setups (dev, staging, production)
  • Network isolation and security (VPC design, private networking, IAM)
  • Container-based workloads using Docker and Kubernetes (EKS)
  • Managed services to reduce operational overhead
  • Disaster recovery and backups

Whenever possible, infrastructure is defined using Infrastructure as Code to ensure reproducibility, auditability, and scalability.

CI/CD & Automation

Automation is a key pillar of my work. I build and maintain CI/CD pipelines that:

  • Automatically build, test, and deploy applications
  • Enforce quality gates and security checks
  • Support multiple deployment strategies (blue/green, rolling updates)
  • Reduce human error and deployment time

Typical tooling includes Jenkins and GitHub Actions, combined with Docker, Terraform, and cloud-native services.

Observability & Reliability

To ensure platform reliability and fast incident response, I implement:

  • Centralized logging and metrics
  • Monitoring and alerting with tools like Prometheus, Grafana, and Datadog
  • SLOs / SLIs to measure platform health
  • Proactive alerting to detect issues before they impact users

I strongly believe that you can’t improve what you don’t measure.

Programming languages and frameworks

Although my primary role is DevOps, I have a strong technical background that allows me to understand and collaborate closely with development teams that use this tech stack.

Tools I frequently use

Leadership & Collaboration

As a DevOps Manager, I also work closely with:

  • Backend, frontend, and mobile teams
  • Product owners and technical leads
  • Security and compliance stakeholders

My responsibilities include:

  • Defining DevOps standards and best practices
  • Mentoring engineers and promoting DevOps culture
  • Supporting architectural decisions
  • Improving delivery workflows and developer experience
