The Client

Caster.IO is an education platform for professional Android developers. The company works with top developers in the industry to produce concise video tutorials on a wide range of Android development topics offered through a subscription-based model.

"I come from a background of mixed media and design, so finding a group that matches my high expectations has been challenging. However, upon reaching out to the team at Vitalsphere Digital, I found that luck had finally paid me a visit.

I hired them to design a custom logo and redesign Caster.IO. From the initial video conference consultation, I found their inquisitive, probing analysis of the project very welcoming. From uncovering concepts, design considerations, user experience recommendations, accessibility implementations, and more, Vitalsphere Digital demonstrated that they were the elite group I’d been looking for.

From that point forward, they continued to deliver exceptional design, front-end development, and product direction that ultimately helped turn Caster.IO into what it is today: a learning destination for thousands of professional developers. Vitalsphere Digital worked within the product specifications, stayed on budget, and delivered all projects before their deadlines. They continue to deliver outstanding results for all projects we have requested and we look forward to a long relationship with them.”

We designed a logo and established a new visual identity for Caster.IO. We teamed up with developer Carlos Jeurissen for a complete visual and technical overhaul of their website and online presence. We created over 60 course illustrations, as well as a template for generating new ones. We continue to work with them to design and implement new features as their site and subscription base grows.
