Ladybug Podcast
We're Emma Bostian, Sidney Buckner, Kelly Vaughn, and Ali Spittel - four seasoned software developers working in different sectors. Since there's a major lack of technical podcasts out there, we've decided to start one. Just kidding -- there's already a ton! 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!
