2026

Dear Hiring Team,

I am writing to introduce myself as a senior Cloud and DevOps engineer with more than twenty years of hands-on experience across enterprise IT, industrial control systems and modern cloud-native architectures. Throughout my career I have helped large enterprises, regulated organisations and fast-moving SaaS providers design, migrate and operate secure, scalable infrastructure on Microsoft Azure, AWS and hybrid environments.

My recent engagements include leading Terraform-based AWS security work for a Fortune 500 social media platform, building and maintaining cloud infrastructure for messaging SaaS, delivering Azure landing zones for a telecommunications group spanning ten countries, running CloudOps for an enterprise unified-communications platform, architecting HIPAA-aligned analytics solutions for a healthcare platform, and engineering the AWS infrastructure behind an AI / LLM-driven pipeline at pharmaceutical scale, work that translates directly to the secure, observable, GPU-aware platforms that today's GenAI and inference workloads depend on. Earlier in my career I led the cloud infrastructure for a global digital-engineering firm, secured industrial control systems against modern threat models, and operated mission-critical systems at a thermal power-generation facility with sustained 99.9% uptime over six years.

I work fluently with Infrastructure as Code (Terraform, Bicep, ARM, CloudFormation), container orchestration (Kubernetes, Helm, EKS, AKS), CI/CD platforms (GitHub Actions, Azure DevOps, Jenkins, CloudBees CI), and observability stacks (Prometheus, Grafana, Loki, Azure Monitor). I am equally comfortable acting as a hands-on engineer, a technical lead mentoring teams, or a trusted advisor translating business needs into pragmatic architectures. I hold current Microsoft Azure expert-level certifications, AWS SysOps, Cisco CCNA, and a Systems Information Engineering degree.

What I bring beyond the tools is judgement: knowing when to migrate, when to refactor and when to leave well alone; aligning cost, security and reliability without playing one against the others; and writing the kind of runbooks, automation and documentation that a team can still rely on a year later. I am available for full-time, fractional or multi-contract remote engagements, open to travel and relocation, and comfortable in Spanish, English and Portuguese working environments.

This is the anonymized version of my CV; specific employer names, end clients and signed engagements can be shared in a follow-up conversation under NDA.

I would welcome the opportunity to discuss how my background could support your team's cloud and DevOps initiatives. You can reach me by email, schedule a call directly through Calendly, or review more detail on my interactive portfolio.

Warm regards,
David Mengarelli
