Since January 2024, I have been enhancing my technical skills at Luckyfit, where I serve as a Full Stack Developer focusing on front-end and back-end development. My front-end work involves utilizing ExtJs, HTML5, and CSS to create engaging, responsive user interfaces. On the back-end, I engage in migrations and the development and enhancement of existing interactors, controllers, and models in a Ruby on Rails environment. This role demands a strong understanding of both the visual and functional elements of web applications, ensuring a seamless and efficient user experience.
Also, I'm working on my own pet project "Book of Recipes". Parallel to my professional journey, I pursued academic excellence, completing a Bachelor of Computer Science at NaUKMA, Kyiv, in July 2022, and currently working towards my Master's degree in the same field.
Continued Learning and Certifications: my dedication to ongoing education is evident from completing courses such as SQL Basics for Data Science from the University of California, Davis, and various specialized courses in machine learning and cloud technology essentials. Additionally, I hold a Certified SAFe Practitioner credential from Scaled Agile, Inc., reflecting my commitment to staying abreast of industry developments and methodologies.
Personal Project: I'm developing the Book of Recipes app, improving my full-stack development capabilities. This project involves using Ruby on Rails for the backend and React for the frontend, along with PostgreSQL, Rspec, Rubocop, Git, Trello, Postman, and ChatGPT4. It highlights my practical application of knowledge and skills in a real-world project.
