About Sergei Ermolov

General informationI’m a Senior Manual QA Engineer with 5 years of experience in startups and product companies. Main domains: logistics, fintech, crypto, HR. I tested web, mobile, desktop, frontend and backend, API. During my career, I solved complex problems: for example, tasks with a large number of components on the backend, and all the functionality in the integration was tested in conjunction. I solved problems related to automated testing - for example, I ran regressions through Jenkins. On one of the products, we (testers) deployed the release ourselves, specifying all the tags and running all the tests (we did the work of autotesters manually), and writing instructions in Confluence. I’m currently actively learning Java. Hard skills - Testing of backend / frontend / web / desktop / iOS / Android / API. - Tools: Postgres / Linux / Zefir / Confluence / Android Studio / adb / Xcode / Charles / Figma / Swagger / GitLab / GitHub / Fidler / Test Link / MSSQL / TestRail / Zeplin / Postman / SOAP UI / SQL / BrowserStack / Sauce Labs / Trello / Azure DevOps . - Using Jira to file bugs.

Soft skills I have strong logic, critical thinking, and am constantly learning something new. I like to immerse myself in tasks and projects, improve the quality of products. I am a team player and feel comfortable interacting with colleagues. Participated in mono-presentations in different languages, where he demonstrated his skills and achievements.
