About

Android Developer with 7+ years of commercial experience in consumer mobile products. In recent years I’ve mainly worked on large-scale media and streaming apps, while also having solid experience beyond a single domain across complex Android codebases. For 2+ years I’ve taken tech-lead responsibility for features: aligning on requirements, planning and ticketing, coordinating Android/iOS/backend work, releasing to production, and validating results via analytics and metrics. Tech Lead of the Middle Android course at Yandex Practicum; occasional Android lecturer on YouTube (e.g., databases/persistence).
