Flaviu Buura

Senior Flutter Architect at Six Flags & Aquarabia (Qiddiya City), Saudi Arabia

One of three lead architects and primary technical owner for the Six Flags Qiddiya City and Aquarabia guest-experience apps — two flagship apps for Saudi Arabia’s Qiddiya giga-project. Designed the shared, reusable authentication package (secure login, token management, session flows) consumed by both apps; defined the modular multi-package architecture enabling Aquarabia to be built on the Six Flags codebase and reuse microservice integrations; drove platform-wide standards on state management, dependency injection and module boundaries; mentored engineers and authored engineering guidelines; integrated AI-assisted development tooling to accelerate delivery, code review and documentation; aligned API contracts with Backend and cross-functional stakeholders.

Senior Flutter Engineer at Crypto Wallet

Architected a secure authentication module using biometrics and PIN flows; engineered an in-app VPN layer for end-to-end encrypted transactions; designed real-time blockchain sync with background processing using WebSockets and Dart Isolates; refactored cold-start sequence with lazy loading and GetIt-based dependency injection; applied Clean Architecture with a modular project structure and SOLID principles; built and maintained CI/CD pipelines with Fastlane and GitLab CI; led weekly code reviews and mentored 3 junior developers on BLoC, DI, and testing practices.

Flutter Team Lead at Dr. Max (Healthcare)

Scaled the Flutter team from 2 to 10 engineers; defined architecture across 3 healthcare apps (BLoC state management, GetIt DI, a modular monorepo structure and a shared component library); introduced structured sprint planning and a delivery framework that improved on-time feature delivery and reduced scope creep; rolled out end-to-end integration testing across all 3 apps, measurably reducing production regression rate; standardized REST API contracts between mobile, backend and QA; provided ongoing 1:1 coaching and technical mentoring; acted as primary technical decision-maker on architecture, tooling and library selection for the mobile platform.
