At Tribuna.com, I lead developers and QA specialists shipping mobile applications for a digital sports media and fan community platform. We shipped 19 new apps for a product with 1,000,000+ MAU.

I integrated Tuist binary caching for Swift builds, reducing total build time by 80%. I also built a Python tool for Firebase Remote Configuration with Slack integration, cutting the time per configuration change by 90%.

At Tribuna.com, I built module scaffolding templates that made end-to-end module creation and integration 95% faster, and a native paywall builder integrated with Adapty that cut new paywall integration time by 75%.

Earlier, I worked on Movix at Itransition Group and iOS projects at EPAM Systems. My work included designing a scalable UI-test architecture, integrating Kotlin Multiplatform into an iOS codebase, and supporting junior developers and trainees.
