👨🔧 As a Cloud Engineer,
I have used approximately 40 services and PaaS/SaaS/IaaS solutions from AWS, Azure and GCP clouds in my projects.
I can design and build; effective cloud solutions and fully automated CI/CD pipelines using Cloud services, and infrastructure automation tools. I can integrate them with the GitHub/Gitlab repository. I can code them with Bash script.
I can securely deploy on the Clouds by using WAF, NACLs, Network Security Groups(NSGs) with FortiClient VPN, Private Subnets, Private VPC, Hashicorp Vault, etc. Also, I can use AWS Security Services for example; Amazon Cognito, Amazon GuardDuty, AWS KMS, Parameter store/Secret manager, Amazon Macie.
I have worked with Artificial Intelligence (AI) services of AWS, Azure and GCP clouds, and implemented projects with Amazon Rekognition. See the link.
In databases; I have worked with Microsoft SQL Server, MySQL, PostgreSQL, and MariaDB, Amazon RDS, Azure SQL DB, and GCP Cloud SQL as a SQL Database. I also worked with Amazon DynamoDB and MangoDB as a NoSQL Database. Also, I did DataBase migration (I moved MySQL DB to AWS Cloud simultaneously without any interruption bu using AWS Database Migration Services (AWS DMS)). I have used pg_dump, DBeaver, AWS DMS, Azure Migrate, and GCP DMS on the cloud or on-premise for migrating and backing up. See the link.
I can use Apache Kafka as an Event Streaming Platform (link), and Amazon SQS (Simple Queue Service) as an Message Queue(MQ) service (link).
I can use MinIO as an Object Storage. See the link.
I would be delighted to take care of the design, planning, management, maintenance and support and other technological tasks associated with an Organization's Cloud Computing Environment.
👨🔧 As a DevOps Engineer,
I am familiar with the Software Development Lifecycle and enjoy using various automation tools to develop CI/CD Pipelines. Especially, I have worked with many CI/CD tools (Jenkins, GitLab CI/CD, GitHub Action, AWS CodePipeline, Azure DevOps Services, etc.). I have used Argo CD together with them when deploying to Kubernetes. The link to my articles about CI/CD tools and the others is cmakkaya.medium.com
I have hands-on experience automating and optimizing deployments, effective configuration management, CI/CD, and DevOps processes in AWS/Azure/GCP clouds. I can use effectively; Ansible as configuration management, Terraform and Cloudformation as infrastructure as a Code, and Nexus open source repository. I have hands-on experience with container technologies like ; Docker, Docker-compose, Docker Swarm, Kubernetes(+Helm), Amazon EKS/ECS, Azure AKS, and Google GKE. See the link,
I can manage multiple Kubernetes' clusters efficiently by using Rancher. See the link.
Also, I can use Prometheus, Grafana, New Relic, Datadog, AWS Cloudwatch, Azure Monitor, ELK Stack-Beats as Monitoring, Logging, and APM tools. I used ELK Stack with Filebeat for log analysis. See the link1, link2.
Applications developed with Java, PHP, Python, .Net, JavaScript; I deployed to the production environment (Docker container or Kubernetes cluster) using Docker and Docker Compose, Kubernetes and Helm, and prepared CI/CD pipelines for them. See the link.
I have knowledge of SDLC methodologies, and able to use Jira as a project management tool and Agile methodology.
I can integrate various systems and tools together. For example;
* Slack-Jenkins, Slack-Grafana, Gmail-Jenkins, Gmail-Grafana, and GitLab-Jira integration,
* Docker image integrations between Jenkins and Artifact Registry Services.
* Peer-to-peer connection for Local-Cloud,
* DataBase-Debezium-Kafka integrations for DB connection,
* Elastic Stack-Postgresql DB connection,
* SSH-Connection for Jenkins-Cloud VMs,
* KafkaUI for managing Kafka topics,
👨🔧 As a DevSecOps Engineer,
I have used SonarQube, Trivy, OWASP Dependency Check, OWASP ZAP, Hashicorp Vault, NACL, Firewall, Private VPC, AmazonCognito, AWS KMS, Azure Key Vault, GCP Cloud KMS, AWS Parameter Store/Secret manager, and Wazuh for SIEM (Security Information and Event Management) in my project. See the link1 , link2 , link3.
For SQL injection, cross-site scripting attacks, and DDoS protection, I use WAF, AWS WAF&Shield, Azure WAF, GCP Cloud Armor in my project, see the link1, link2 .
For SIEM (Security Information and Event Management); Wazuh and FortiLogger.
👨🔧 As a Data Engineer,
I use AWS Glue as an ETL(Extract, Transform, and Load) and data catalog management tool, Amazon Athena as a data query and analyze tool, Amazon QuickSight as a visualization tool, and Amazon S3 data lake as a data lake storage tool in my project. See the link1 , link2.
👨🔧 As a Proactive Team Player,
I always is eager to collaborate and contribute to the success of his team and the company. I have always been appreciated and consulted by my colleagues in the places I worked. I am confident that I will reach the same level in a short time in any company too. Also, I like to work professionally in teamwork but also like to work independently.
I am making great efforts to develop myself to design cloud-native microservice architectures and orchestration solutions for deployment of applications that have been the prominent DevOps subject of recent years.
As you can see my Education section below, I can approach and solve problems from different perspectives with the training I have received in different disciplines in the fields of science. At the same time, these trainings allow me to establish better dialogues with my teammates.
✍️ As a Writer,
I publish my articles about Cloud and DevOps, especially Security and CI/CD on Medium . I have nearly 100 Medium articles related to all of my works. I'd love for you to take a look at them. And I have added my projects to GitHub. I think, I'm very good at documentation. I can contribute to your company in this regard.
