Technologies: Ruby on Rails, Vue.js, MongoDB, RSpec, Capybara, FactoryBot, REST API, Heroku, Vega-Lite, GeoJSON, Rubocop, Brakeman, LintersMore information:While working on the project, I have learned Vue.js and a lot from the front-end developers. Thanks to this, I can perform both back-end and front-end tasks.I am responsible for the project support, including analyzing and implementing business tasks. I conduct code reviews to ensure code quality and alignment with business requirements.Also I have written onboarding documentation for the project. Onboarding time of new colleagues has been significantly reduced.I have initiated the process of creating project documentation. Now methods of working with already existing services are well documented. This documentation significantly accelerates the development and integration of new services, while also promoting their reusability.- Social network for founders of startups. Technologies: Ruby on Rails, PostgreSQL, RSpec, Render, Rubocop, little experience with HotwireMore information:My team and I had to refactor and improve this project while developing new features. During the refactoring process, patterns such as “Factory”, “Decorator”, “Adapter”, “Iterator” were used. After refactoring, the speed of further development increased, and the project pages began to render faster.I solved the problem of selecting the optimal course for the user based on his answers to questions. A service has been created that calculates the greatest intersection of user interests with courses and abstracts from their implementation. The dry-validation library was used to validate (by user answers) new entities, such as courses and communities. Show less

Technologies: Ruby on Rails, PostgreSQL, Sidekiq, GeoJSON, JSON Schema, REST API, Prawn, AASM, RSpec, Capybara, FactoryBot, Rubocop, implementation of microservice architecture.More Information:I had successfully moved the generation of legal documents into a separate microservice. It has accelerated the speed of creation, corrections and changes of the documents. The time for testing and deploying changes has been reduced from 15 to 2 minutes. It is also allowed to generate documents for new systems.I have also integrated several third-party systems via API. For example, a cartographic system. Points and polygons with information are created/updated/deleted in real time.- Information system for citywide discussions.
