Experience
Git Repository Migration
This project involved migrating over 1,000 repositories from GitHub to GitLab with all the data, hierarchies, PR history, commit history, and comments. I created all the users and implemented a group policy for security. All of this activity has been completed with proper planning and execution without any downtime.
Cloud Cost Optimization
The AWS usage costs were $2 million per year, and a reduction was requested. I implemented a strategy to identify all unutilized or underutilized resources, removing or downgrading them, which led to a cost reduction from $2 million to $1.1 million, achieving nearly a 50% decrease.
Elasticsearch/Graylog Storage Optimization
Encountered issues with excessive Graylog storage usage in Elasticsearch. I identified and deployed tools to back up old data to the cloud storage, freeing up space by removing it from the existing system, with the capability to restore when needed.
