About me
As a Ruby Developer with over 8 years of experience, I specialize in designing, developing, and maintaining complex web applications across various domains, including E-commerce, fintech and online video platforms. I’m truly passionate about problem-solving and have a keen attention to detail. My coding skills are strengthened by sharp analytical thinking, and I excel as an effective team player by fostering open communication, actively contributing ideas and collaborating on solutions that drive project success. I follow best practices, SOLID and DRY principles and use a variety of techniques including caching, asynchronous processing and efficient database management for handling large-scale web applications. Leveraging the rich features of the Ruby language and modern gems like dry-rb, I am primed to consistently deliver robust and reliable solutions. Presently, I am located in Tbilisi, Georgia, but I am willing to relocate to Germany.
