● Building automated testing processes for both the backend and frontend from scratch in accordance with the testing pyramid. ● Establishing guidelines for test automation that enable developers to write and maintain automated tests more effectively. ● Standardizing test frameworks across the organization for increased efficiency and transparency. ● Introducing AllureTestOps to display and analyze test results. ● Developing a comprehensive testing strategy for the entire company. ● Improving recruitment processes for Automation QA and Backend, and conducting interviews for Python, pytest, Docker, K8s, Linux, and DBMS.

I am responsible for the quality of our internal framework based on Apache Airflow, which allows you to create a batch pipeline for loading, processing and uploading data. Automates deployment and integration with the Tinkoff data ecosystem. Achievements: ● The current unit tests have been expanded and refactored (redundancy and irrelevant checks), new ones are being reviewed. ● Functional tests from unit are highlighted, integration tests are implemented (they are part of the release pipeline). ● Got rid of dependent unit tests, ensured isolation Each test uses a unique DAG (empty /template with the necessary operators). Provided hybrid parallelism of tests: - Unit ~9 minutes → ~2 minutes 40 seconds. - Functional ~10 minutes → ~4 minutes 15 seconds. - Integration ~10 minutes → ~2 minutes. ● Lowered the threshold for entering development into testing features - pytest fixtures, utils, helpers, mock/test data, checkers. ● The preservation of intermediate and final test artifacts is ensured, as well as improved perception through allure step and the time of their execution. ● Implemented integration with a team developing a set of functions and classes implementing ETL transformations. Accordingly, their test data is used to verify our implementation of operators. ● Basic test cases for e2e UI tests are described, on the basis of which automated tests are made on Cypress. ● Analyzed and described the relevant tasks on the separation of business logic and the creation of thin controllers for development and testing. Additionally: ● Advising other DWH teams in the context of building automation processes. ● Teaching Python and automation to DWH QA Engineers from scratch. ● Participating as an interviewer of the Python section, reviewing of autotests, general technical sections (Docker / Linux / DBMS). ● I am responsible for the quality of our internal framework based on Apache Airflow, which allows you to create a batch pipeline for loading, processing and.

Achievements: ● Ensured the quality of integration (API interaction) with its own internal supplier, as well as the most important external ones, their monitoring and support. ● Implemented the tasks necessary for business, such as: search in the past; early check-in / late check-out.differentiation of suppliers' inventory by sales channels. ● Prepared a roadmap of infrastructure and quality assurance for low-level hotels' searching and booking services: - Deploy individual branches (avoiding the trunk based model). - Adding additional nodes to the development environment. - Mock server. ● Updated outdated text and technical documentation, thereby lowering the threshold for employees to enter the search and booking services in particular. ● Trained a QA trainee from scratch in the direct integration team. ● Became a mentor for 10 new employees. Developed utilities for: ● Getting logs of a low-level hotels' searching service with attribution settings for the required sales channel. ● Generating a secure payment token (card data) for a low-level hotels' booking service with payment system management. ● Generating a set of test JSON files for manual checks of low-level hotels' searching and booking services, depending on the supplier's input data. ● Generating dynamic (instead of hard-coded) test data before each run of autotests.

● Conducting manual tests on Zgate and Traffic Control products to ensure no confidential information is leaked on mail servers such as MS Exchange Server and IBM Domino Server. ● Carrying out manual tests on web products including: - DLP - a centralized information security management system. - Reports - access to databases containing incident information. - Event Log - access to logs with information about internal system events. - OCR - a text recognition system for graphic files. ● Developing and maintaining test documentation. ● Working with external customers, from implementation to resolving any issues during use.
