Mobile product engineer building calm, native-first experiences.

Jan Janovec

Mobile developer shipping native and multiplatform products.

I help teams deliver polished iOS, Android, and Kotlin/Compose Multiplatform apps — choosing the right mix of native and shared tech to move fast without sacrificing quality.

I care about the details that make products feel trustworthy—tight feedback loops, accessible flows, and launch-ready polish. If your next mobile milestone needs someone who can guide it end-to-end, I’d love to help.
