GitHub Blog
A place for combining all of my findings in IaC architecture, software design, and computer science. It may also contain topics about Terraform, testing, and automation tools. The blog is updated from time to time.

Load Balancing Solution

I developed a load balancing solution capable of passing through traffic for hundreds of customer environments for mid-to large-size enterprise customers. I was capable of architecture solutions based on open-source and cloud technologies, developing an automated process of configuration updates for client needs, configuring Web Application Firewall, and developing custom security profiles for various applications.

Deployment Framework for Oracle Cluster in AWS

I was deeply engaged in developing automated solutions to create Oracle DB clusters in AWS. During this project, I addressed infrastructure and network requirements and developed a pipeline to provide the required resources. Also, I was deeply involved in performance testing and tuning.

Automated Application Delivery with GitOps

I developed a company-wide delivery process based on the GitOps concept. I was responsible for improving the CI part of SDLC for multiple applications. Also, I created a secure connection between each component of the delivery system. Additional security checks were added to the pipeline. Also, I made a simple process for developers to update applications in test environments and, based on it, automated ways to update applications in a production environment.
