About

Rendani Manugeni.

I'm a software engineer, designer, and founder based on Earth. I build software, AI, and digital systems with an obsession for simplicity, longevity, and craftsmanship.

Currently CEO of Hjulmund and Hjulmund Studios—building intelligent software and creative digital experiences. I'm also the mind behind Voidenmark, my independent software and product development practice.

My work sits at the intersection of systems thinking and beautiful engineering. I believe in performance first, minimalism always, and building things that outlast trends.

Principles

  • Minimalism
  • Systems over trends
  • Long-term thinking
  • Performance first
  • Beautiful engineering

Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.

— Antoine de Saint-Exupéry
