PonishaFull-time DevOps Engineer - remote
Nov. 2022Iran, Tehran- Led the migration from a legacy codebase and infrastructure to a modern clustered stack (Galera, Elasticsearch, MinIO, RabbitMQ, Redis, NGINX, HAProxy), followed by ongoing optimization and maintenance.
- Directed a second, larger migration to Kubernetes, deploying production-ready clusters with Helm, ArgoCD, and Traefik, and managing official Helm charts for Percona, MongoDB, Redis, RabbitMQ, and Elasticsearch.
- Implemented Change Data Capture (CDC) pipelines using Kafka and Debezium, enabling zero-downtime migrations for critical databases; integrated additional tools (e.g. Superset) for data team needs.
- Enabled the platform to handle 3x higher traffic while reducing infrastructure costs by 75\% compared to the previous production setup.
- Established enterprise-grade observability with Prometheus, Grafana, Loki, and Fluent Bit, and designed robust backup strategies (full, incremental, PITR).
- Cloud-ready architecture across networking, identity, storage, and observability, making on-prem/managed K8s patterns directly portable to AWS patterns (EKS/VPC/IAM/S3/RDS) when required.
