I’ve been a "Full Stack" dev for three years, but I feel like a "jack of all trades, master of none." Would I be better off specializing in something like Distributed Systems, Cloud Infrastructure, or Frontend Performance to increase my market value? Or is being a generalist safer during economic downturns because you can fill more roles?

The most successful developers I know follow a "T-shaped" model. This means you have a broad understanding of the entire stack (the top of the T), but you go very deep into one specific area (the vertical bar). This gives you the versatility of a generalist to collaborate with different teams, but the high salary potential of a specialist. For example, be a great Full Stack dev, but become the "go-to" person for PostgreSQL performance tuning. That niche expertise makes you indispensable and harder to lay off.
Julia, for someone just starting their "deep dive," how do you identify which niche is actually going to be profitable in the long run?
I found that being a generalist in a startup is great, but big tech companies (FAANG) almost always hire for specific niches. It really depends on the company size you prefer.
That's a very practical observation, Monica. In small teams, you wear many hats, but in large orgs, they want you to be the master of your specific domain.
Douglas, look for "pain points." What is the one thing your senior devs always complain about or struggle with? If it's something complex like WebAssembly, Security compliance, or Kubernetes orchestration, that’s your niche. Follow the complexity, because where there is complexity, there is a demand for specialists who can simplify it.
