Hi, I'm

Daniel Segura

I build

I’m a DevOps, SRE and platform engineer with over 11 years on AWS. For the last five and a half I was on Ocado Technology’s observability team — monitoring, logging, alerting and on-call for a containerised estate on ECS — where I drove the consolidation of New Relic, Datadog and PagerDuty onto Grafana Cloud, with significant savings.

Now I work freelance. I like infrastructure that is reliable, observable and boring to operate, and I’ve run Kubernetes from the control plane up — my own clusters with Kubespray and Ansible, and GKE and EKS in production — so I know what the managed versions hide.

Freelance

Senior DevOps Engineer

Ocado Technology

Part of the Observability team, operating the monitoring, logging, alerting and on-call platforms — Grafana Cloud, Prometheus, Fluent Bit and PagerDuty — for a containerised AWS estate running on ECS. Helped internal teams unify the metrics and logs of their applications, ran the GitLab CI/CD pipelines behind auto-releases, and worked with developers to improve visibility, debugging and incident response across the platform.

  • Cost optimisation. Drove significant savings by consolidating observability on Grafana Cloud: metrics and logs moved off New Relic and Datadog, and on-call moved from PagerDuty to Grafana IRM after five years on it. Introduced governance practices and fine-grained permissions for Grafana stacks and AWS resources.
  • Automation. Built dynamic pipelines around a single source of truth and Python tooling against several APIs, enabling automated deployments and removing engineering hours lost to manual work and human error.
  • Infrastructure as Code. Authored and maintained reusable Terraform modules, and supported the developers building and releasing an internal Terraform provider, accelerating infrastructure standardisation.
  • Collaboration. Led the initiative to build a shared code space for the observability teams, and partnered with the cloud teams to define least-privilege AWS roles for observability services.
  • Operational excellence. Automated dependency management with Renovate to keep updates secure and timely, and helped teams adopt solid on-call practices.

Site Reliability Engineer

CAPSiDE

Ran production systems for customers on AWS and Google Cloud — including Kubernetes on GKE and EKS — from architecture and migration through to day-to-day operation and incident response.

  • Architecture and migration. Designed and built systems for mission-critical projects, from architecture and migration planning to continuous operation and improvement.
  • Reliability. Responded to incidents, found the root cause, fixed the underlying problem and designed the improvement so it would not recur.
  • Performance. Analysed and improved performance and scalability, and automated systems management with Ansible and Terraform.
  • Customers. Worked directly with customers — many of them leading companies in their industry — to understand their needs and design the solution.
