* Configured test environments on Linux servers for SM projects (Web Based) on (Usually for Ubuntu 22.04 and Centos 7 based distributions). Some Web projects migrate from Hetzner and OVH cloud to various cloud providers such as GCP.* Depending on the server environment used for cyber security, network policies were created for dedicated servers and cloud servers and VPN using UFW/Iptables on external firewall or Linux Kernel.* CI/CD processes were migrated from Github Actions to Jenkins (Jenkins configured on Hetzner for testing and CI/CD processes). End-to-end CI/CD Pipelines Configured for more than 25 Web projects* Migrating Docker images to Artifact Registry to Container Registry for Dopinger project on GCP for GKE.* While building frontend and backend environments for the dopinger project in GCP, Dockerfiles were updated to use cache layers correctly for cost and resource optimization.* Configured ELK Stack on Linux machine for SEO Analytics team.* Index based Data Views were created and security policies were set for Analytics via Kibana* Configured Apache Kafka Cluster for Event-Driven Development (with Debezium and Kafka UI, with Kraft architecture).* Consumers were written with Spring AMQP and Spring Data Elasticsearch to insert the logs coming from the PHP Backend to elasticsearch. (event-driven design). Outbox pattern was used to keep error logs, and error logs were configured to be written schematically to Apache Kafka via the Global Exception handler.* CDC was written for Redis as Custom with Redis Pub/Sub together with the Backend Team. Thus, per-service redis architecture was implemented. Python-based Subscribers written for Redis Subscriber.*Redis Cluster was configured for high traffic services (12 nodes).*Prometheus and Grafana set up for Server Monitoring.*Nginx configurations on existing servers were maintained for Reverse Proxy. Configured Nginx on GCP for projects.* Monitoring and alert system configured for cronjobs.
