Who we are

Founders

  • Ranil Arieta

    Founder & Solutions Architect

    He works on the load-bearing parts: frameworks, backends, and the architecture decisions that are expensive to reverse. Primarily C# and Angular, with a growing focus on where AI genuinely fits into a product rather than where it merely decorates one. At RaJuKe he leads solution architecture, turning a client's problem into a system that still makes sense three years later.

    • 20+ Years
    • C# / Angular / AI

  • Judy Yee

    Founder & Graphic Designer

    She works the seam where interface decisions become engineering ones, leading UI and UX at RaJuKe while staying fluent in the code her designs land in — C#, Angular, React, and AI solutions. That fluency is why her work survives contact with implementation instead of being renegotiated during it.

    • 20+ Years
    • UI/UX / Angular / React

  • Kent Fong

    Founder & Solutions Architect

    His range comes from shipping across the whole stack rather than one slice of it. He works in C#, Angular, React, and AI solutions, and owns the DevOps side at RaJuKe — the pipelines, environments, and release paths that decide whether good code ever actually reaches anyone.
