Adam J.
DevOps Engineer and Cloud Infrastructure Specialist based in Israel, with 5 years of hands-on experience designing CI/CD platforms, container orchestration systems, and infrastructure-as-code pipelines. I build for reliability, reproducibility, and developer velocity — then document everything.
I have worked across high-growth startups and scale-ups, owning platform engineering solo and alongside product engineering teams. Currently available for full-time roles and senior consulting engagements.
Software & Tools
Projects
Migrated 40+ production microservices from Amazon ECS to EKS with zero downtime using a phased canary approach and Terraform-managed infrastructure.
Built a self-service GitOps platform enabling 15 engineering teams to deploy independently, cutting lead time from 4 hours to under 8 minutes.
Designed and codified a multi-region AWS architecture across eu-west-1 and us-east-1 with VPC peering, Route 53 failover, and RDS read replicas.
Deployed a centralized monitoring stack across all production K8s workloads, reducing MTTD from 18 minutes to under 2 minutes.
Replaced hardcoded credentials and SSM Parameter Store with Vault dynamic secrets across 60+ services, achieving full rotation with zero developer friction.
Built a scheduled DR test pipeline that validates RTO/RPO targets monthly, replacing a manual quarterly process that took 3 engineers 2 full days.
Services
Design and maintain end-to-end delivery pipelines using GitHub Actions, GitLab CI, and ArgoCD — from commit to production with zero manual steps.
Deploy and operate Kubernetes clusters on EKS, GKE, and bare-metal. Helm chart authoring, resource tuning, and multi-namespace governance.
Infrastructure design and cost optimisation across AWS and GCP — VPC networking, IAM policies, auto-scaling groups, and multi-region setups.
Full Terraform and Ansible codebases for repeatable, version-controlled environments. Module design, remote state management, and drift detection.
End-to-end observability stacks with Prometheus, Grafana, and the ELK stack — dashboards, alerting rules, and on-call runbooks included.
Shift-left security practices: SAST/DAST in pipelines, container image scanning with Trivy, secrets management via Vault, and policy enforcement with OPA.
Certifications
Writing
Hard-won lessons from running ArgoCD across 15 teams — sync waves, app-of-apps patterns, RBAC pitfalls, and the drift detection edge cases that will catch you off guard.
How we moved from a monolithic Terraform repo to a composable module registry, enabling 8 teams to ship infrastructure independently without stepping on each other.
