Professional profile
Iurie Plesu
DevOps and Platform Engineer focused on Kubernetes, AWS infrastructure, Terraform, Kafka, GitOps, observability and reliable delivery automation.
Professional summary
I build cloud and platform systems with a practical focus on deployment, observability, infrastructure automation and clean operational boundaries. My engineering work includes a Kafka streaming platform on Kubernetes, an EKS operational toolset and Terraform-managed AWS foundations with private networking.
Core skills
Kubernetes & Platform
Kubernetes, Helm, Strimzi, ArgoCD, Karpenter, ingress-nginx, ExternalDNS, RBAC and readiness handling.
Automation & Delivery
Terraform, Docker, CI/CD workflows, image delivery, controlled apply flows, deployment dependencies and rollback planning.
Observability & Data
Kafka, PostgreSQL, Prometheus, Grafana, logging, service health, operational dashboards and API-backed data flows.
Selected engineering work
Event streaming platform
Kafka Streaming Platform
Designed an event path from Python producers through Kafka KRaft and a consumer API into PostgreSQL and a browser dashboard.
- Configured three combined KRaft broker/controller nodes with replication factor 3 and minimum ISR 2.
- Used six ArgoCD sync waves to order namespace, operator, Kafka, persistence, services and exposure.
Platform operations
EKS Platform Tools
Structured the day-two EKS layer around Karpenter, observability, ingress, DNS automation, RBAC and runner workloads.
- Applied Spot-first t3/t3a capacity, 30-second consolidation, seven-day expiry and hard NodePool resource caps.
- Documented 100% Spot usage across a 22-day tagged Cost Explorer period with no On-Demand fallback used.
Infrastructure automation
EKS Terraform Infrastructure
Built a Terraform-managed EKS foundation with private IPv6-primary workers, AWS service endpoints, IAM and remote state.
- Separated VPC and EKS responsibilities across three AZs, six subnets and seven AWS service endpoints.
- Verified IPv6 node and pod networking, DNS resolution and outbound IPv6 connectivity.
AI-assisted delivery
FitBack Coach and Engineering Workflows
Used AI-assisted requirement analysis, product iteration, engineering documentation and browser QA while keeping final technical judgment and verification explicit.
