Jan 2025 - Present • 1 yr 4 mos
Working as a Full-Stack Flutter Developer at Crytonix Code, responsible for developing, maintaining, and improving cross-platform mobile applications. My role involves translating UI/UX designs into pixel-perfect Flutter interfaces using designs provided in Figma and Adobe XD, ensuring responsiveness, performance, and consistency across devices. I actively work with Firebase services, including user authentication, Cloud Firestore, Realtime Database, Cloud Storage, Cloud Functions, and Firebase Cloud Messaging for push notifications. I integrate and consume REST APIs to enable dynamic data flow between mobile applications and backend services. My responsibilities also include implementing Google Maps features such as location tracking, markers, and map-based interactions, as well as integrating payment gateways to support secure and reliable in-app transactions. I collaborate closely with Node.js developers to connect Flutter applications with backend systems, coordinate API requirements, and ensure smooth communication between frontend and backend components. I participate in code reviews, debugging, and performance optimization to maintain code quality and application stability. Additionally, I follow best development practices, version control workflows, and contribute to team collaboration to deliver scalable and maintainable mobile solutions.
