It's been about four years since I've been podcasting at Confluent, and "Streaming Audio" has been on hiatus for a little more than two, but I've got great news: we are back! We're back with a new name, a new format, and new hosts. Welcome to the Confluent Developer Podcast, where we talk to software developers of all stripes about some of the most interesting problems they've solved in their career. I'll be joined by my co-hosts, Adi Polak and Viktor Gamov. And hey, you know, we're all basically Kafka people, so of course, we're going to gravitate towards experts in data streaming and the technologies relevant in that space. But you know what? We're not limited to that. Really, we want to talk to developers of all kinds about the toughest problems they've solved and how that process changed them and changed the environment around them. So join us. We're launching September 22 with weekly episodes on the Confluent Developer YouTube channel or wherever it is you get your podcasts. We'll see you soon.SEASON 2 Hosted by Tim Berglund, Adi Polak and Viktor Gamov Produced and Edited by Noelle Gallagher, Peter Furia and Nurie Mohamed Music by Coastal Kites Artwork by Phil Vo 🎧 Subscribe to Confluent Developer wherever you listen to podcasts. ▶️ Subscribe on YouTube, and hit the 🔔 to catch new episodes. 👍 If you enjoyed this, please leave us a rating. 🎧 Confluent also has a podcast for tech leaders: "Life Is But A Stream" hosted by our friend, Joseph Morais.
