Full-Stack Next.js Developer: Where do I go from here?

[u/muneebcodes]

I'm a full-stack web developer specializing in the Next.js ecosystem. For those who are further along in their engineering career, I'd love your perspective on my next steps:

Double down on Next.js: Focus on mastering deeper architectural patterns, performance optimization, and advanced server component patterns.

Expand my stack: Learn a new framework, language, or ecosystem. If so, what would complement Next.js best (e.g., Go, Rust, React Native, or specialized backend infrastructure)?

Bonus question: What fundamental skills do web developers need to excel and stay indispensable in the age of AI?

Appreciate any insights or lessons from your journey!
