Zinnia

• an enterprise operations management platform
• in English: code that helps a team organize work, people, and equipment in one place
• named after the fourth track on Clairo's 2021 album Sling

Executive rundown

• Zinnia is like Jira mixed with ServiceNow. People can create work orders, assign them, track assets, and watch updates happen live.

Tech stack

• C# to write the backend programs
• ASP.NET Core to turn those programs into web APIs
• React to build the website people use
• TypeScript to make the website code easier to maintain
• PostgreSQL to remember work orders, assets, and users
• SignalR to instantly show updates without refreshing the page
• Docker to package everything so it runs the same everywhere
• AWS ECS to run the packaged application in the cloud
• Terraform to create the cloud infrastructure automatically
• GitHub Actions to automatically test and deploy new code
• CloudWatch to monitor the application and catch problems
