First Talk Description:
• Code Architecture and AI
Carter Levin, Software Engineer at Duolingo

AI is great at writing apps from scratch, but struggles to consistently capture the conventions and context of a larger codebase. Without explicit guidance the architecture and patterns an LLM uses today are often incompatible with those used yesterday. I’ll be presenting on how we’ve set up a pipeline of scripts, prompts and templates to guide LLM code generation flows toward a set of constant architectural patterns and cue it into our codebase specific context.

Carter has been at Duolingo for over 6 years. In his free time he plays squash and is interested in game design.

Second Talk Description:
• Designing Simplicity: Our Team’s Path into The Composable Architecture
Alexander Saenko, Field CTO at Sigma Software, Co‑founder of iOSUkraine

I will talk about how our team embraced The Composable Architecture to tame complexity and achieve cleaner code. I’ll share the challenges, lessons learned, and the key principles that guided our implementation.

Alexander is Field CTO @ Sigma Software. He started his career as an iOS engineer over 12 years ago and has experience in different domains such as ad tech, healthcare, hospitality & retail software, etc. He organized different iOS events, including one of the biggest conferences in Ukraine for iOS engineers, iOSUkraine.

Alexander has been working with mobile apps and related technologies since 2012, back when manual reference counting in Objective‑C was still common. He began his career as an iOS engineer and later gained experience with a range of mobile technologies, including PhoneGap, Cordova, Android, React Native, Xamarin, and Flutter.

After building a strong engineering foundation, Alexander moved into hybrid engineering/management roles to better understand both customer and team needs, become more involved in business processes, and broaden his expertise into full‑stack development. He has mentored mobile engineers at his company and served as a trainer at “Sigma University,” where he taught students.

Alexander has also been an organizer of the “Kharkiv iOS User Groups” and the “iOS Ukraine” conferences, both of which have held multiple editions. He has spoken at multiple conferences in Ukraine and Brazil, and this will be his first appearance at a conference in the United States.
