• Conducted testing of a microservice web application for the sale of new cars, including services for adding additional products, payment systems and the formation of documents for the execution of transactions.• Identified vulnerabilities in the user experience and the logic of the system, which contributed to the launch of car sales in the early stages of development. He provided technical support and advice to users, which allowed to increase the number of successful transactions by 20% monthly.• Implemented early testing, which reduced the development time and delivery of features by half.• Carried out onboarding and mentoring for new members of the test team from the Junior to Middle level, as well as distributed tasks between them.• Collected and provided up-to-date product information for the preparation of release notes and demonstration in front of the business team.Tools:• DevTools: Used for functional and UI testing, including defect localization.• Charles: Intercepted and spoofed traffic to test various scenarios and localize defects. I installed stubs on non-working methods to bypass errors and continue testing.• Postman: Tested changes in the backend logic, created collections of queries and API autotests.• DBeaver: Tested database content, collected data for testing via the API, and compiled SQL queries to prepare reports.• Jira: I started the detected defects, tracked the tasks and their current progress using JQL commands. He distributed testing tasks, was engaged in planning and evaluating QA tasks.• Confluence: Compiled and maintained test documentation, as well as reviewed documentation from other team members.• Platformeco: Localization of defects through traces of the called method. Analysis of the logic and structure of the backend for the design of test documentation.
