HN – Ask HN: How important are stacks and specialization?

Over the last year's I have worked in different roles and with different technologies. Python, Go, C, TS/React, domain specific languages and tooling, and played with frameworks like Elm and Svelte. Mainly in the areas of web, technical simulations, and DataScience.

I would argue that I am flexible but that comes at a cost, low specialization.

My question: To build a career, how much do tech stacks matter? Should I stick to one (React, FastAPI, PostgreSQL) or doesn't it really matter as long as I can ship something? Is it fine to use Svelte for a new project when breaking into the market or should I stick to React?

Note: I worked in different roles not described as SWE but in practice I am writing code full time for almost 3 years. Building a career refers to "becoming officially a SWE".
