About Dimitrios

Staff SRE and DevOps architect with 15+ years of experience designing and operating large-scale, multi-cloud infrastructure - primarily on AWS, Azure, and GCP. Based in Ticino, Switzerland, I work with engineering teams across the DACH region and beyond as an independent consultant through Swiss GmbH.

My core focus is reliability engineering at scale: multi-region cloud architecture, infrastructure-as-code (Pulumi, Terraform), observability, and cloud networking. Most recently, I led the Feature Flags SRE team at CloudBees, owning a 20+ AWS account multi-region platform and driving the IaC migration from Terraform to Pulumi.

I specialise in Agentic SRE - applying AI agent frameworks (Claude Agent SDK, AWS Bedrock) to infrastructure operations: network observability, anomaly detection, and automated remediation. This is where infrastructure engineering meets the next generation of operational tooling.

If you need a senior technical partner for infrastructure architecture, SRE transformation, or a hands-on engagement to bring your platform reliability and observability to the next level - let's talk.

Experience

  • CloudBees Inc
    Staff Operations Engineer | SRE DevOps Tech Lead
    TECH
    August 2021 - June 2026 (4 years and 10 months)
    Switzerland
    • Team Leadership: Served as Tech Lead for the Feature Flags SRE team - set technical direction and infrastructure roadmap, ran Scrum ceremonies, and guided 3 engineers across reliability, observability, and deployment workflows.
    • Cloud Architecture: Designed and operated a multi-region AWS infrastructure (US-East, US-West) for the CloudBees DevSecOps SaaS platform, spanning 20+ AWS accounts across shared SaaS and fully isolated single-tenant environments.
    • Next-Gen SRE: Built the organisation's first network observability layer using the Claude Agent SDK and AWS Bedrock - establishing baseline traffic visibility and anomaly detection across EKS and AWS where none existed before. Traffic analysis identified routing inefficiencies that, by shifting to internal VPC endpoints, eliminated ~$2k/month in NAT Gateway processing costs in production alone.
    • Performance Engineering: Optimised CDN configuration for the Feature Flags product, reducing flag evaluation latency for EU customers from ~500ms to under 100ms - an 80% improvement without infrastructure changes.
    • Modern Deployments: Built and operated CI/CD pipelines spanning every environment type - SaaS production, pre-prod, QA, test, and customer demo environments, plus fully isolated single-tenant AWS accounts. Extended the same pipeline framework to automate customer network interconnections.
    • IaC Migration: Migrated core infrastructure from Terraform to Pulumi (Python/Go) when HCL ran out of expressiveness for conditional multi-tenant networking - automating isolated single-tenant deployments into independent AWS accounts, with dynamic CIDR validation and real unit and integration tests.
    • Customer Architecture: Represented CloudBees in enterprise sales and pre-sales engagements - assessed customer network topologies, proposed and explained interconnection architectures (Transit Gateway, IPsec VPN, private connectivity), and translated complex infrastructure requirements into implementable solutions.

  • Smart Reporting GmbH
    Senior DevOps Engineer
    SOFTWARE PUBLISHING
    May 2020 - June 2021 (1 year and 1 month)
    Munich, Germany
    • Team Leadership: Led a team of 3 DevOps and 2 IT engineers, establishing Agile/Scrum ceremonies that increased deployment transparency and team velocity.
    • Platform Delivery: Delivered the cloud version of the radiology reporting platform on AWS - introducing IaC-controlled, structured cloud infrastructure for a 50-developer engineering org that previously had no standardised provisioning. Maintained parallel on-premise containerised installations. Unified identity management across Azure Active Directory and AWS.
    • Kubernetes & EKS Migration: Introduced EKS and container immutability standards - replaced a workflow where developers SSHed into long-lived containers and edited files directly with proper image-based, immutable deployments.
    • Release Engineering: Built the complete release infrastructure from scratch - GitLab CI pipelines across QA, pre-prod, and production, Terraform-managed AWS environments, and Packer-based image builds for on-premise deployments - where no structured release process existed before.

  • AstraZeneca (DE)
    Senior DevOps Engineer
    BIOTECH
    July 2019 - May 2020 (10 months)
    Munich, Germany
    • Engineering Leadership: Directed internal engineers and external contractors across the full infrastructure lifecycle; led technical hiring for the DevOps team and mentored junior engineers.
    • Cloud Migration Strategy: Spearheaded the migration of 200+ VMs from on-premise to AWS; architected and automated the hybrid-cloud environment using Terraform and Ansible.
    • GxP Architectural Lead: Led the design and implementation of infrastructure architectures that met strict GxP requirements; functioned as the technical lead for infrastructure audits.
    • CAPA & Audit Leadership: Led the DevOps team through 2-3 GxP infrastructure audits contributing to successful ISO certification - operationalised Corrective and Preventive Actions (CAPA) within the DevOps process, ensuring automated guardrails and technical controls met regulatory requirements.
    • Change Management: Introduced an ITIL-based change management process for infrastructure - establishing structured approval workflows, change request procedures, and rollback standards that aligned DevOps practices with GxP regulatory requirements.
