Ladybug Podcast
We're Emma Bostian, Sidney Buckner, Kelly Vaughn, and Ali Spittel - four seasoned software developers working in different sectors.

But, we wanted to add our voices to the space and share our experiences and advice. We'll have great discussions around how to start coding, the hot technologies right now, how to get your first developer job, and more!
