As a highly skilled Senior DevOps Engineer with extensive experience in team management and cloud infrastructure, I've successfully built and led a team of 10 to create a cloud-native infrastructure that can handle over 2 billion daily requests with high availability. I achieved over 99.9% uptime for Tapsell and reduced resource usage by at least 30% for Mediaad while maintaining a response time of less than 50ms to ad requests. In addition, I've prepared a cloud-native infrastructure for the UnifiedAd Platform, built a Kubernetes Operator with Go to automate backups, and implemented systems to optimize 10TB of data. My work resulted in improved performance and cost savings. I've developed an automated internal platform for ArgoCD and deployed a centralized monitoring environment using Prometheus and Grafana. I've also incorporated Apache Druid, Delta Lake, and Apache Spark using Kubernetes Operator to improve scalability for Tapsell's Machine Learning as a Service (MLASS) Platform. Furthermore, I implemented Argo Workflow to automate complex machine learning workflows, reducing the time to production by 40%. As a Technical Lead at Mediaad, I served as the CTO and led the development of the platform using Kotlin with the Spring framework, Kafka, Cassandra, Elasticsearch, MongoDB, Redis, and Kubernetes. I migrated the existing codebase to a reactive model, reducing resource usage by at least 30% while maintaining a response time of less than 50ms to ad requests. As a Senior Software Engineer and DevOps Engineer at Backtory, I designed and implemented a real-time messaging web service with Spring framework using WebSocket on Kubernetes that handles over 2000 CCU. I developed and managed a 100TB object storage service using GlusterFS and a linearly scalable distributed CDN solution for Backtory's platform. I also managed and enhanced DevOps flow for Backtory's services, achieving 99.96% uptime. My technical skills include Docker, Kubernetes, Linux, AWS, GCP, Terraform, Ansible, Bash, Python, Kotlin, Java, Go, Nginx, Prometheus, Grafana, Graylog, Apache Spark, Spring Framework, Git, Jenkins, Helm, ArgoCD, ELK, Kafka, Cassandra, Redis, MongoDB, PostgreSQL, and MySQL. I hold a Master's and Bachelor's degree in Computer Engineering from Sharif University of Technology.
