Cross-Platform App Developer | FlutterFlow

May 2026 - Aug 2026 • 3 mos

Designed and 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.

Mobile App & SaaS Developer

Mar 2026 - Jul 2026 • 4 mos

Contributed to the development of mobile applications and SaaS products for startups and growing businesses, specializing in rapid product development with FlutterFlow and Flutter. Converted product concepts, wireframes, and high-fidelity Figma designs into responsive application experiences for iOS, Android, and web. Handled application architecture, database planning, authentication, API connectivity, backend workflows, reusable components, and responsive layouts. Developed features such as customer portals, booking systems, marketplaces, content platforms, admin dashboards, subscription-based services, and business management tools. Worked closely with product stakeholders throughout development to clarify requirements, identify edge cases, and improve the user journey before implementation. Debugged application logic, optimized database interactions, resolved UI inconsistencies, and prepared builds for testing and release. Focused on creating applications that were not only visually polished but also structured for easier maintenance, iteration, and future feature expansion.

Mobile Solutions Developer | FlutterFlow & Backend Integration

Feb 2026 - Jun 2026 • 4 mos

Developed tailored mobile and web solutions for businesses seeking to digitize services, improve customer experiences, or launch new technology-driven products. Combined FlutterFlow development with backend services and API integrations to deliver applications that supported real business workflows rather than simple interface prototypes. Implemented complete user journeys from registration and onboarding through account management and core application functionality. Developed dashboards, booking systems, marketplaces, content platforms, customer portals, administrative tools, and other feature-driven applications according to project specifications. Converted Figma layouts into responsive FlutterFlow screens while maintaining reusable components and consistent design behavior across devices. Connected applications to Firebase and Supabase for authentication, databases, storage, and backend operations, with attention to appropriate data structures and access control. Worked with APIs and third-party services to extend application functionality, including data retrieval, submission workflows, automated processes, and external service connections. Where native FlutterFlow capabilities were limited, implemented custom logic and Flutter/Dart solutions to meet specific requirements. Also handled application testing and troubleshooting, diagnosing issues involving action flows, database queries, authentication, state management, API responses, and responsive layouts. Collaborated with clients throughout development to clarify requirements, review progress, and make informed adjustments. Focused on delivering clean, reliable applications that could be maintained and expanded efficiently as business requirements changed.
