The Concatenate Conference, a virtual event organized by Microsoft engineers in response to visa challenges faced by Nigerian developers, successfully brought together developers from around the world with attendees tuning in in-person from Lagos, Nigeria and speakers participating remotely via conference call. The event's blend of in-person and remote interactions proved to be incredibly successful, providing ample opportunities for networking and learning. Despite being an experiment with less than a month's notice, the event was an immense success, featuring talks by notable speakers such as Sarah Drasner, Jeremy Keith, and Mina Markham.
