What I'm looking for

I’m looking to lead mobile delivery and architecture end-to-end—building Flutter apps with strong DDD/Clean Architecture, reliable CI/CD, reusable packages, and a collaborative, international team that ships fast.

I’m a Flutter specialist and mobile tech lead with 6+ years building cross-platform applications for iOS and Android. I’ve been an early Flutter adopter—shipping in production since early 2019, shortly after its first stable release.

In my current role, I lead mobile development for a U.S. client and grew from sole developer to team lead. I defined the architecture using Domain-Driven Design (DDD), own delivery planning and sprint coordination (Jira), and coordinate stakeholders while still contributing hands-on code.

I’ve handled the full mobile lifecycle—architecture, CI/CD, shared package design, and release management on Google Play and the Apple App Store. I also architected and maintain a versioned, reusable Flutter package library (audio, GraphQL core, and more) shared across multiple apps.

I’m driven by scale and product impact: I helped migrate a high-traffic product (several million downloads, 500,000+ monthly active users) to Flutter to improve reach and performance. Alongside leadership, I’ve delivered features like a robust social feed, multi-user chat, and an experimental Flutter Web CMS to streamline content operations.
