What skills should a Frontend Developer focus on after 5-6 years of experience?

You should focus on going deeper instead of wider at this stage. Invest time in areas like design systems, accessibility, performance, testing, and system design for large frontends. Once you have that down, learning some backend basics with Node and a database can be helpful. For AI, try building real product features around LLM APIs rather than just creating simple chatbots. Also, enhancing your communication skills, writing documentation, and mentoring others are crucial, as that mix keeps you employable in today's market.

I recommend delving into system design and architecture, especially since it pairs well with AI and LLM integrations. You might find it useful to start by getting LLMs to adhere to the design patterns you set, which can lead to fruitful projects on both fronts.

Honestly, at your experience level, moving from just a "UI implementer" to a "feature owner" can make a big difference. Learning backend basics, how to design systems, and integrating AI APIs into actual products will really boost your value. Understanding performance, architecture, and the trade-offs in product development is also key. Developers who can manage end-to-end feature development are highly sought after.

I think jumping right into "grind backend or you're doomed" is a bit extreme at your level! The best leverage is probably honing your system design skills and taking ownership of features end-to-end. A bit of backend and infrastructure knowledge is useful, along with some understanding of AI and LLM integration—not heavy ML, just how to seamlessly plug them into real products. Frontend will continue to be relevant, but standout developers will be those who can connect the dots between frontend, APIs, data, and a bit of cloud, without needing a whole team to do it.

A fun approach is to learn prompt engineering for tackling coding challenges, making you look "full-stack" on your resume! But seriously, focusing on system design and backend fundamentals can really pay off. Frontend devs that understand data flow avoid building chaotic systems.
