  Project All-flyers.com - aggregator of discounts and special offers- Made transition from legacy code to ReactJS (Next.js + koa.js), which gave: access to the rapid integration of ready-made modules and plugins, reduced the need to document the code, reduced the time to familiarize new developers with the project- Transferred work in the company from the Hg version control system to Git (used bitbucket.org)- SEO-optimization: sitemap generation for more than 50 thousand pages, opengraph, Schema.org, etc.For the first time for the company:- Implemented the CSS framework Material-UI, which made it possible to quickly layout simple pages by developers, without hiring a layout designer- I used microservice architecture and application containerization, which helped to distribute tasks between developers, balance the load on the server and increase fault tolerance.- I implemented a ready-made third-party microservice for converting, processing, caching and uploading images to users (used nodejs streams)- I used automatically generated GraphQL interfaces based on Postgres and Hasura. Both the development of the API and the work with the database have become easier from a single UI, the need for third-party solutions (pgAdmin, etc.) has completely disappeared.- Created a microservice for multi-threaded crawling / parsing using PuppeteerJS, AMQP RabbitMQ queue manager and ChildProcess technology in node.js, as a result of which it was possible to fully utilize server resources, prevent data loss during crashes, in some cases it was possible to reduce the execution time of scripts from10 hours to 20 minutes.Project InShop.lv - discount aggregator- Created a section on the site in Frontend and Backend side- Сode refactoring in important modules Show less
