Ilya founded Nerdy Production and leads its engineering. Before that he was CTO of QIWI, one of Russia's largest payment platforms, and a principal developer at Yandex, where he worked on Yandex.Auto — taking native Android deep into the vehicle, with heavy CAN-bus integration through a custom CAN shield. He was also a principal at Evotor, whose point-of-sale devices run on a forked AOSP, giving him a low-level view of Android most app developers never touch. He has been building software since 2010 and shipping production Flutter since 2018, and now leads delivery on the agency's flagship apps — from the chart-heavy fintech UI of ExtraETF to the fully custom design system of Arcana. He writes most of the essays on this blog and maintains the agency's open-source work, including the dxpdf DOCX-to-PDF engine. He works across Flutter, Go, Rust, TypeScript, Kotlin, Kubernetes, and Docker, with a focus on app architecture, cross-platform delivery, and building teams that ship.
