About

Senior Flutter Developer with strong experience building and scaling cross-platform mobile applications in production environments. I focus on writing maintainable, well-structured code and on solving complex problems around state management, performance, and platform constraints.

I’ve worked on consumer-facing apps with real-time features, media-heavy workflows, subscriptions, and monetization, and I enjoy collaborating closely with product and design to turn ambiguous requirements into robust solutions.

I value clear ownership, thoughtful architecture, and teams that care about quality without over-engineering.
