About Us

Welcome to Erevos Technologies, led by Ioannis Tzoumas. We are a DevOps and cloud engineering practice focused on helping teams ship faster and operate more reliably. Our expertise spans the major cloud providers (AWS, Azure, GCP), CI/CD automation with GitHub Actions, Jenkins, and Bitbucket Pipelines, and container orchestration on Kubernetes with Helm — including GPU-accelerated clusters for machine learning and AI workloads. We treat infrastructure as code with Terraform, keep systems consistent with Ansible configuration management, and deliver deep visibility through Prometheus, Grafana, and CloudWatch. From landing zones to production observability, we build platforms that are secure, scalable, and automated end to end.

Portfolio

A selection of our DevOps and cloud engineering engagements across cloud platforms, CI/CD, Kubernetes, infrastructure as code, and observability.

AWS EKS Platform with Terraform & GitHub Actions

Designed and deployed a scalable AWS EKS Kubernetes platform provisioned entirely with Terraform, with GitHub Actions pipelines automating build, test, and deployment.

GPU Kubernetes Cluster for ML Training

Built a GPU-enabled Kubernetes cluster with Helm-managed workloads and node autoscaling to run large-scale machine learning training and inference jobs cost-effectively.

Multi-Cloud Landing Zone (AWS, Azure, GCP)

Implemented secure, standardized landing zones across AWS, Azure, and GCP using reusable Terraform modules and consistent IAM and networking guardrails.

Observability Stack with Prometheus & Grafana

Deployed a full observability stack using Prometheus, Grafana, and Alertmanager, delivering actionable dashboards, SLO tracking, and reduced alert noise.

Ansible Configuration Management Automation

Automated fleet-wide server configuration, hardening, and patch management with idempotent Ansible playbooks and dynamic inventories.

CI/CD + GitOps for Microservices

Built CI/CD and GitOps delivery for a microservices architecture across GitHub Actions, Jenkins, and Bitbucket Pipelines — with caching, automated testing, and pull-request-driven, gated deployments to multiple environments.

CloudWatch Monitoring & Alerting

Built native AWS observability with CloudWatch metrics, logs, and alarms wired into on-call workflows for fast incident response.

Terraform Module Library & GitOps

Created an internal Terraform module library with a GitOps workflow, standardizing infrastructure patterns and enabling pull-request-driven changes.

Grow with Google Certified Trainer — AI & Cloud

Certified Grow with Google trainer for AI and Cloud, delivering hands-on workshops and seminars that upskill teams and organizations on modern cloud and AI practices.
