What we're about

As Visuality, for the past 15 years, we've built countless apps for multiple industries. Throughout this time we've encountered many challenges, that gave us skills and know-how how to deal with the design and architecture.

Almost every month we meet at our office to share the knowledge. Visuality's meetups became very popular in the Ruby on Rails community. We now want to reach out to all of you that cannot appear at our office in person.

One of the most noteworthy accomplishments is the shift towards Domain-Driven Design. For us it was one of the most interesting discoveries that not only helps us grow, but also pushes us to be closer to the dev community.

This time we decided we wanted to share some of this knowledge. We cordially invite you to our webinar that we hope will motivate you to research and implement DDD in your projects.
