I made a challenge for myself–during 100 days learned something new in web development and wrote 100 articles on different topics. The challenge was a success.

Yandex.Collections is a service that allows users to collect images and research exciting topics through enriched image content. I started as a front-end software engineer and later expanded my responsibilities to DevOps and infrastructure.

I have multiple accomplishments in this project:
Implemented a robust streaming server-side rendering for Node.js, which improved the metrics TTFB (time to the first byte) from approximately one second to 70 milliseconds (14x).
Developed, from scratch, an extensible masonry solution working at 60fps.
Scaled a Node.js application to run on a cluster of 15 machines in three separate data centers under a load of around 100 requests per second (RPS); set up the rolling update deployment and weighted balancing.
Created an Elastic and Kibana cluster to process server and client logs. Set up logging and logs rotation in a multiprocess Node.js application.
Moved a large codebase from ES6 to TypeScript.

Adform is one of the world's largest private and independent advertising technology companies. I started as a technical lead for a team of three engineers. I quickly moved to the software architect position, where I was defining the technology direction for all front-end engineers in the company.

My accomplishments include the following:
Completed a large step-by-step refactoring of a legacy codebase from Backbone.js to React and GraphQL.
Organized AdformJS–internal knowledge-sharing meetups for all engineers in the company. Summary: 10 meetups, 27 talks, and 120 unique attendees.
Built visual tests solution for the company–a tool and approach for UI/UX automatic regression tests.
Researched and developed a new unified application development architecture to be used by 50 front-end engineers in the company.
Developed a CI/CD pipeline for all front-end applications in the company.

StudyQA is a smart search platform for programs, universities, and scholarships worldwide that aims to help students from developing countries. It helps them to find universities and colleges which suit their interest and match their background and financial resources. I worked here as a software engineer.

My accomplishments include the following:
Developed a smart search platform for programs, universities, and scholarships worldwide.
Integrated a couple of externals API, including Stripe for subscription payments, Mailjet for email campaigns, and Aviasales for partnership programs.
Built a system for processing a large amount of abnormal data and extracting facts from it.

The repository with algorithms on ACM topics.

It contains:
1. A binary search.
2. A comparison of the search algorithms.
3. Dijkstra's and Ford's graph searching algorithms based on adjacency class, binary heap, dynamic list, static and dynamic stack, Treap, and solutions for ACMP tasks.
