Hi, I’m Kyle, the only QA engineer on Avvy at AnotherBall. QA has been this size since the beginning, with a part-time QA joining for very large features. What changed is the workload. AI sped up our developers and the dev team grew, so every release has more to test. QA stayed small and still keeps pace with development, without slowing releases down. Avvy is a live-streaming app where you appea…

Hello! I’m @apippo from the AnotherBall Mobile Team. We built a bridge code generator that keeps Unity, Android, and iOS APIs aligned using one C# contract. In a previous post, Davide wrote about how our game development and native app work come together inside Avvy. I also come from a game development background. Over the years, I have worked with Unity/C#, Unreal/C++, Kotlin, and Swif…

Hi! I’m @fortkle, Tech Lead and Engineering Lead for the Avvy division at AnotherBall. Alongside product development, I also conduct first-round interviews for server-side engineers. Recently, I made a small change to how I ask questions in those interviews. It was not a major redesign of the interview process. I simply split what had previously been a single design question into several stages. …

Hi! I’m Tsuji, a server-side engineer at AnotherBall. Most days I’m writing backend code, or chasing an infrastructure alert down a rabbit hole and shaving a yak somewhere along the way. What to Do With the Room AI Frees UpHow is AI working out for you these days? AnotherBall is no exception — we use AI company-wide, for development and for plenty of things that aren’t development. How AI Put Our…

Today I want to talk about what a team with mixed backgrounds brings to the table — the friction, the upsides, and how AI can help smooth things out. Different problems to solveAt a fundamental l…
