"In the blue ocean, everything we do is an innovation!"
Since our foundation, it has been RakSul's belief that technology can bring significant structural changes to many old-style industries. The vast majority of these industries haven't been empowered by modern software engineering. At RakSul, we pride ourselves on our spirit of innovation. To demonstrate this, we have created numerous services, which include but aren't limited to print order dispatchers, PDF data-checking services, and gang-printing engines. When you are in a blue ocean, we believe it's important for everything you do to be significant. Why build software that only slightly outperforms your competitors?
Ruby has been a central technology to make this vision come true. We support the Ruby community as it continues to be a key driver in realizing our mission.
