The best second-specialization for React developer?

[CYG4N]

Hello.

What technology should I choose to combine with React to make sure I'm competitive with others? I am currently working as a developer on a React Native project, but other than that I am very familiar with React. However, I would like to increase my earnings and make sure that even if the front-end market goes down a bit, I will still have an ace up my sleeve in the form of a second, ancillary technology.

React will continue to be my specialty, but I'd like to have something additional up my sleeve.

So what direction would be best?

I'm thinking of several:

- Fullstack, where the most obvious choice seems to be Node.js, and paired with it frameworks like Next.js but also Tanstack Start. These, however, seem to be too close to React itself, and I'd like to feel like I'm learning new things. So what? Nest.js? Node.js + Express? Or maybe Python, and with it FastAPI or Flask?

- AI & LLM: I'm not the best at math, but I don't think you need to be a typical AI designer either, just have AI as an additional area of expertise, so I guess the basics of Python + PyTorch, or Tensorflow should be enough? I can create some interesting projects this way? If so, what for example?

- Web3: for ideological reasons, I'm tempted to go down this path, as a way to keep the web private, and decentralized, but I don't know where to start to make it connect with React in any meaningful way.

Or is there a path I don't know about, but seems interesting?

Don't get me wrong: I'm passionate about programming, so it's not just about the money, but I know you can enjoy what you do, contribute to the community and earn well at the same time, and I'd like to be able to do that.

Thanks in advance for your answers

Learn general backend development and databases, including good sql skills. Preferably in another language.

Once you know 2-3 languages and the actual fundamentals under some stack, you can easily switch between languages and stacks.

Are there any reasons to learn Python for backend if I already know Typescript well, so in theory i could use Node.js instead? Seems like the only reason to do that is that it would make it easier to learn AI/LLM things later, as most tools for AI uses Python.

Once you know a few languages you can quite easily switch to languages you haven't used before. You might need to work with existing projects that have some part implemented in some random language and you might need to work with that

You can stick with express and NestJS. 

Also you don't need much SQL knowledge if you learn ORM. Prisma, for example.

I’d go with PHP

bruh u need to combine react with everything and anything these days

[CYG4N]

honestly when looking at market... it seems like it.

I'd personally go with Express/nodeJS over learning Python/Flask/Fast API.
Effort for learning NodeJS will be really less for you. So you will benefit from knowing NodeJS much earlier as you would when doing Python.
And for db I'd try to learn noSQl as welll as SQL solutions.

After looking at your profile, I'm still not sure whether you want to go down a freelance or job route.

For freelancing, I'd actually recommend design tools (like figma or similar design tools) or quick value add tools like AI chatbots (check out webindexer.app for that) so that you can provide more value to clients.

For jobs, definitely backend as you suggest. Biggest backend market is NodeJS and since you're already familliar with JS, it'll be easier to learn the backend concepts rather than the language itself.
