carlos@corex.co  ·  LinkedIn  ·  GitHub  ·  Talks

Summary

Tech lead with 17 years of experience designing, building, and operating cloud-native platforms and leading engineering teams by example. I specialise in turning manual, error-prone infrastructure processes into fully automated, secure, and compliant systems — from landing zones and reusable CI/CD pipelines to multi-tenant Kubernetes architectures. I teach, coach, and share knowledge as a core part of how I raise the bar for the teams I work with, both internally and through public speaking at conferences and meetups.

Experience

Cloud Engineer — Jumbo

Amsterdam, Netherlands (Remote) · November 2022 – December 2025

  • Designed and implemented Azure Landing Zones to standardise how development teams deploy to the cloud, replacing a fragmented process where each team had to devise their own solution.
  • Automated the full landing zone provisioning workflow: subscription creation, VNET peering with the central hub, IAM configuration, and CI/CD pipeline access — eliminating weeks of manual work and third-party dependency per onboarding.
  • Authored and enforced Azure Policies across all landing zones to ensure compliance with organisational security and governance standards.
  • Built reusable CI/CD pipelines in GitHub Actions, enabling the most mature teams to deploy multiple times per day.
  • Provisioned and managed infrastructure using Terraform and Python, with GitHub Actions orchestrating all automation.

Software Developer — 84codes

Remote · October 2025 – December 2025

  • Designed and built a hardware-to-cloud demo kit for conferences and workshops, showcasing LavinMQ with real sensor data instead of synthetic inputs.
  • Programmed ESP32 boards with DHT11 sensors (C++/Arduino) to push temperature and humidity readings to LavinMQ queues.
  • Developed a Ruby backend to forward queue messages to a central Prometheus instance connected to Grafana dashboards for live visualisation.
  • Containerised the full development environment with Docker and automated deployments to Heroku via GitHub Actions CI/CD pipelines.

Team Lead DevOps — GrandVision

Amsterdam, Netherlands · November 2020 – November 2022

  • Led a team of 5 senior DevOps engineers to architect and operate a multi-tenant, cloud-native microservices platform on Azure (AKS, EventHub, CosmosDB, API Management, Application Gateway).
  • Owned all infrastructure provisioning with Terraform and all deployment automation via Azure DevOps Pipelines.
  • Collaborated closely with the Product Owner to balance platform stability with rapid feature delivery.
  • Introduced Portable Pipelines — reusable, composable CI/CD pipeline templates that scaled across the microservices architecture and reduced pipeline duplication.

Lead DevOps / Security Engineer — ING

Amsterdam, Netherlands · October 2018 – August 2020

  • Managed and extended a large-scale CI/CD platform (GitLab, Mesos, Marathon, CephFS) running 1,500+ Jenkins and SonarQube instances serving the global engineering organisation.
  • Led the migration from on-premises CI/CD infrastructure to Azure DevOps, deploying Azure Pipelines Agents on-prem in a hybrid model.
  • Designed and built the entire monitoring stack for the hybrid CI/CD platform; containerised Azure Pipelines Agents, reducing multi-datacenter deployment time from ~25 minutes to ~5 minutes.
  • Ensured SOx compliance for all CI/CD tooling; implemented multi-tenant access controls to isolate team assets.
  • Ran a bi-weekly 4-hour “Chapter Time” learning module, teaching engineers across the organisation about Docker, Terraform, Kubernetes, AWS, Azure, and Azure DevOps.

Amsterdam, Netherlands · July 2015 – August 2018

  • Researched, developed, and integrated programmable infrastructure tooling (Terraform, Kubernetes, Mesos, Ansible, Jenkins) for clients undergoing cloud-native transformations.
