- Dynamic routes for blog posts, career positions, and team members
- GSAP animations (marquee, counters, button hovers)
- IntersectionObserver-based scroll reveal (blur-to-clear transitions)
- Dark mode with next-themes
- React Hook Form + Zod contact form
- Framer Motion page transitions
- Lottie animations via lottie-web
