SUMMARY
With over 4.5 years of experience in mobile app development using React Native, I
specialize in creating efficient and scalable solutions for both iOS and Android platforms.
Additionally, I possess strong back-end development skills utilizing Node.js and the Firebase
ecosystem to build robust APIs and scalable serverless architectures.
I am proficient in TypeScript, Next.js, Redux/React-Redux, Firebase, Google Maps API,
and WebSocket, which I use to implement real-time functionality. In my practice, I actively
utilize native modules (Java) to integrate platform-specific features such as geolocation
and camera access. I work in an Agile environment, regularly collaborating with my team
for sprint planning, code reviews, and product improvements.
Key achievements include:
● Developing high-performance mobile applications with optimized memory
management and fast loading times.
● Implementing advanced geolocation features, such as real-time tracking and
geofencing, using the Google Maps API.
● Integrating Firebase for user authentication, push notifications, analytics, database
management, and cloud storage.
● Collaborating with UI/UX designers to implement precise design mockups and
animations.
● I continuously enhance my skills to create useful, scalable, and user-focused
solutions, aiming to implement innovative solutions keeping up with the latest
technological trends.
