Ukraine · Kyiv · 4 years of experience · Advanced/Fluent ·Published 2 May
On the backend side, I have developed and maintained several high-performance applications using Django, integrating PostgreSQL and other relational databases to ensure data integrity and speed. My expertise also extends to implementing NoSQL databases, which allows me to select the most suitable storage solution based on the project requirements.
In addition to my core programming skills, I have extensive experience with task queue management using Celery and message brokers like Redis, enhancing the responsiveness and scalability of web applications. My projects often involve containerization with Docker, which streamlines development, supports continuous integration/continuous deployment (CI/CD) processes, and assures consistency across various development environments.
I am adept at navigating complex problem-solving scenarios and have a track record of delivering projects that meet high standards of quality and user experience. I'm keen to leverage my skills in a dynamic team where I can contribute to impactful projects and continue growing as a part of a forward-thinking company.
