I was instrumental in enhancing the stability, performance, and security of the enterprise IT infrastructure at Gözen Digital Aviation. I ensured the reliability and efficiency of Linux-based systems, managed virtualization platforms and backup operations using Veeam to support business continuity, and streamlined configuration management processes through Ansible automation. In addition, I oversaw load balancing and DNS operations on Cloudflare, implemented geo-steering strategies to optimize traffic distribution across multiple regions, and contributed to SSL/TLS configuration and certificate validation processes. I also conducted multi-region error analysis and successfully planned and executed DNS migrations in production environments, ensuring uninterrupted service continuity.
Measure, Monitor, Master: Unlock Observability! I've launched a blog focused on Observability, where I'll be sharing the latest and most comprehensive insights in the field. I'll write in-depth articles about APM (Application Performance Management) and observability products from around the world, highlighting the strengths, challenges, and use cases of each tool. On my blog, I will be covering the biggest and most popular APM companies and their products, including: Dynatrace - Dynatrace Platform New Relic - New Relic One Datadog - Datadog APM AppDynamics - AppDynamics APM Elastic - Elastic APM Zabbix and Grafana Monitoring IBM Instana Opentelemetry I will also touch upon SRE (Site Reliability Engineering), which combines software engineering and operational practices to improve the reliability and efficiency of systems. SRE is crucial for monitoring and performance management, especially in large-scale environments. If you're interested in software development, system monitoring, and performance management, make sure to check out my blog!
Presidency of Religious Affairs (Diyanet) I have extensive experience administering servers on Ubuntu, Debian, and Rocky Linux, including installation, configuration, LVM-based disk resizing, system upgrades, security patching, performance tuning and DNS Server Administration, scripting languages, LDAP, routing protocols and storage technologies (NAS or SAN). In addition, Windows Server Family environments were deployed, maintained, updated, and hardened for enterprise standards. I managed Zimbra Mail Server and Proxmox Mail Gateway to enhance email reliability and efficiency. Samba Directory and Active Directory structures, including Windows Group Policies and Security Policies, were designed, implemented, and maintained. Audit logs from Nginx, Apache, Active Directory, Windows Audit, and DNS services were collected and sent to SIEM systems, enabling centralized monitoring and correlation analysis for security events. VMware clusters, including vSphere, were installed, configured, and maintained, while storage and SAN solutions were deployed. Virtual servers, pools, and load balancing algorithms were implemented on F5 Load Balancers. Databases such as MSSQL, MySQL, and PostgreSQL were installed, configured, and monitored. Backup and configuration processes for network devices were automated using Ansible and AWX. Within Application Performance Monitoring (APM), performance metrics were analyzed, and root cause analysis was performed using Dynatrace, AppDynamics, and IBM Instana. Linux, Windows, storage, virtualization, websites, and network structures were monitored with Zabbix, with dashboards created in Grafana for visualization and reporting.
