Andrej V.
QA engineer
I create innovative mobile and software solutions that enhance user experiences and streamline processes. With proven experience in developing Kotlin-based Android apps using Jetpack Compose and MVI architecture, I bring projects like Catalist to life, featuring interactive elements and external API integrations. My skills extend to Python and CUDA, where I implemented advanced parallel image processing systems with multithreading and multiprocessing. I specialize in building reusable libraries for report generation and designing microservices with robust authentication and asynchronous notifications. In addition, I have practical experience in software testing and quality assurance, including unit, integration, and end-to-end testing, applying both white-box and black-box techniques to ensure reliability and high code quality. If you’re seeking a developer who combines technical expertise with a strong focus on quality and user-centered design, let’s discuss how I can contribute to your next project.
