Ayşe Yalçındağ

I am a highly skilled full-stack developer with extensive experience in both Android development and backend systems using Node.js. With a strong focus on performance, security, and scalability, I specialize in crafting responsive and user-friendly mobile applications and robust backend services. In Android development, I design and implement intuitive, high-performance applications using Java and Kotlin. I have a deep understanding of the Android platform, from UI/UX design to integrating advanced features like real-time communication, video streaming, and encryption for secure data transmission. On the backend, I am proficient in building secure, efficient, and scalable APIs with Node.js. I am experienced in working with databases, including MySQL, and implementing advanced security features such as JWT authentication, encryption protocols (e.g., Diffie-Hellman, AES-256-GCM), and ensuring secure communication with RESTful and gRPC APIs. Additionally, I have worked with microservices and containerization to create flexible and scalable system architectures. My expertise extends to optimizing database queries, handling high-volume messaging and file-sharing services, and ensuring the security and privacy of user data. I also have experience with cloud technologies like AWS, utilizing services such as S3 for storage and CDN for efficient content delivery. Besides these, remotely, I had worked at Google as an Android developer, and at Jobot as a Node.js developer earlier. I am committed to staying up-to-date with the latest industry trends, continually expanding my skill set, and delivering high-quality solutions that meet the needs of modern software applications.
