Tips for Great Projects
Make it real. Solve an actual problem, even a small one. "Built a Kubernetes cluster to deploy my personal blog" is more impressive than a tutorial clone.
Document everything. A repo with a great README beats one with better code but no explanation. Include: what it does, why you built it, how to run it, what you learned.
Show your thinking. In interviews, you'll be asked: "Why did you choose X over Y?" Have a reason. Architecture decisions matter.
Iterate publicly. Make commits regularly. Employers look at commit history. 10 commits over a week shows real work; 1 commit with everything shows you copied it.
