About

I’m Brian Kayfitz, a senior software engineer with 15+ years of experience building and scaling consumer applications and backend systems in production, including event-driven and asynchronous architectures. I’ve led end-to-end product development for travel and healthcare platforms, working on everything from hands-on payments and subscriptions to designing high-scale APIs that keep real users moving smoothly through the product.

Most recently, I’ve been leading development of a travel platform serving 2.5M+ users, with deep experience architecting entitlement and purchase validation for in-app purchases and subscriptions. I also enjoy building cross-platform mobile experiences (Flutter, Dart, iOS/Swift) and cloud infrastructure (AWS, CI/CD, Infrastructure as Code), with a strong focus on performance, reliability, and product-driven iteration.
