Cross-Platform App Developer

FlutterFlow • Freelance

Aug 2025 - Present • 1 yr 3 mos

Developed cross-platform mobile applications for businesses and early-stage companies looking to validate and launch digital products efficiently. Worked across the complete development process, starting with product requirements and interface designs and continuing through application logic, backend connectivity, testing, and release preparation. Converted Figma designs and product concepts into responsive interfaces with reusable components and structured navigation. Developed user onboarding, authentication, account management, dashboards, search, filtering, booking, messaging, content management, and transaction-related workflows depending on project requirements. Used FlutterFlow to accelerate application development while applying custom Flutter and Dart solutions when projects required functionality beyond native platform capabilities. Connected applications to Firebase and Supabase for authentication, databases, storage, and backend operations, while designing data structures that could accommodate additional features as products evolved. Integrated REST APIs and third-party services, configured application state, implemented conditional workflows, and resolved issues involving data synchronization and user interactions. Regularly reviewed existing builds to identify inefficient workflows, inconsistent interfaces, broken actions, and technical limitations. Worked directly with product owners to translate business requirements into practical technical solutions. Maintained a strong focus on usability, reliability, and maintainability so applications could move from prototype to a dependable product rather than remaining as demonstration builds.
