Software Engineer at DoorDash
When I was building ATGATT as a solo founder, I was primarily concerned about the cost required to deploy the app to production, along with speed of development. Given this requirement, I landed on Go because of its minimal memory usage, allowing me to run the entire site on the cheapest possible EC2 VM (free tier!). Even with 1000 concurrent users active at the same time, I never see more than 20% memory usage or 10% CPU usage in production. Go is also an extremely simple language to work with in terms of features and syntax, while still maintaining type safety, an important characteristic when the codebase grows in size.
