I am a Flutter / Full-Stack Developer with hands-on experience building complete production-ready systems from scratch. I specialize in developing mobile and web applications using Flutter, as well as implementing backend logic with Firebase Functions (Node.js). I work extensively with Firestore, Firebase Auth, Cloud Run, and event-driven architectures, where all critical business logic, state management, time tracking, and billing calculations are handled strictly on the server, while the client is responsible only for displaying real-time data.
I have real-world experience integrating IoT devices, including electric scooters, using MQTT and the Flespi platform. I have implemented real-time device control, telemetry processing, location and speed tracking, and remote lock and unlock commands. I designed and built a scalable electric scooter rental system supporting rental start, pause, resume, completion, and automatic termination without client involvement, ensuring full server-side control, data consistency, and protection against balance and state errors.
I actively use artificial intelligence as an engineering tool. ChatGPT and GitHub Copilot are part of my daily workflow for system architecture design, backend and frontend optimization, edge-case analysis, and accelerating development while maintaining code quality. I follow best practices for configuration security, use environment variables for keys and tokens, and clearly separate development and production environments.
I am focused on building stable, secure, and scalable business-oriented solutions. I am comfortable owning the entire technical stack, making architectural decisions, and delivering projects to production rather than working only on isolated UI components.
