Vladimir Putilov

Dear Hiring Team, My name is Vladimir Putilov, and I am interested in the position of Senior iOS Developer / Team Lead Mobile Development / Head of Mobile. I have more than 15 years of experience in mobile development and team leadership, with a strong focus on building scalable multi-platform solutions (iOS / Android / Kotlin Multiplatform) and establishing predictable delivery processes within product teams. I have worked in international companies across Europe and Australia, where I was responsible for both mobile system architecture and team/process development. At my current company, Infobric (Sweden), I lead a cross-platform team (iOS, Android, API), develop mobile products with up to 30k DAU, and oversee the entire development lifecycle — from architecture and engineering standards to CI/CD and release management. Key achievements include:
• Reduced technical debt by 60% through systematic legacy code migration and architecture unification, accelerating new feature development by 30%
• Reduced time-to-market from 2–3 weeks to 1 week by implementing CI/CD pipelines using GitLab and Fastlane
• Improved application stability: reduced crash rate by 40% and achieved a crash-free rate above 99%
• Introduced Kotlin Multiplatform, reducing code duplication between platforms by 20–30%
• Established engineering standards and development processes that improved onboarding speed and delivery quality
Previously, I launched mobile products from scratch, including streaming and social platforms, designed architectures using VIPER and Clean Architecture principles, implemented high-load functionality (LIVE/VOD streaming), and built and mentored development teams. My key value lies not only in software development itself, but in applying a systematic approach to mobile engineering. I build architectures, processes, and teams in a way that enables products to scale efficiently, keeps releases predictable, and ensures development remains manageable and effective. I would be glad to discuss how my experience can contribute to your team and business goals.
