Instead of querying the database every time, applications can retrieve cached data from Redis.

Have you used Atlassian tools?

Yes. I'm familiar with Atlassian products such as Jira for sprint planning, ticket tracking, and Agile workflows, and Confluence for documentation and knowledge sharing. In professional and academic projects, I've worked in environments where tasks were organized through ticket-based workflows similar to Jira.
