Track record of scaling regression coverage for payment gateway APIs, cutting documentation time by 50% with custom AI agents (n8n, local Ollama), and building a Python-based neural network that unlocked full automation coverage in CAPTCHA-restricted areas — work that sits at the intersection of QA and applied AI engineering. Owns test infrastructure end-to-end: containerized environments (Docker, Portainer), CI/CD pipelines (Jenkins, GitLab, CircleCI), log analysis (Sentry, Kibana), and direct data validation with SQL (DBeaver) and MongoDB. Thrives in fast-paced, ambiguous environments, turning complex business requirements into structured, maintainable test suites rather than ad-hocs.Affiliate experience No data availableWork experience6 years 2 monthsMay 2023 - May 2026(3 years 1 month)Company under NDAQA Engineer• Built and scaled a Type/Playwright test suite structured around the Page Object Model, increasing regression coverage for payment gateway APIs. • Developed a Python-based neural network to handle CAPTCHA in QA/staging environments, enabling full automation coverage in restricted product areas. • Built AI agents using n8n and local Ollama 3 for automated generation of test cases and checklists, reducing documentation time by 50%. • Deployed and managed isolated Docker environments via Portainer, ensuring environment parity across dev/QA teams. • Configured and maintained automated test pipelines in CircleCI, integrating the Playwright suite into the release process. • Used DBeaver for SQL validation and ran basic MongoDB queries to verify data integrity during API testing. • Investigated production issues and tracked error rates via Sentry and Kibana logs; implemented a domain status checker to monitor system availability and DDoS protection during releases.December 2022 - April 2023(5 months)LLC "ELS"QA Engineer• Built the company's testing process from the ground up. • Developed test documentation. • Developed a Playwright (JS/TS) automation framework and integrated it into CI/CD to speed up regression runs and new-feature delivery to production. • Worked across multiple projects within the company.February 2020 - September 2022(2 years 8 months)Heckny LogistikQA Engineer• Testing of an internal customs/logistics e-commerce platform for integration with Ozon Global. • Checklists and test documentation. • UI/UX testing and bug reporting. • Testing of the cargo tracking system. • Testing of the software integration with the customs warehouse for cargo-quantity reporting. • Writing unit tests in JS/TS (Playwright).SkillsJavaScript (Node.js)PlaywrightPage Object Modelreusable fixturesAPI testing (Postman)web/mobile testingUI/UX verificationmanual and automated regression testingDocker (Compose)PortainerLinux (Bash)CI/CD (Jenkins, GitLab, CircleCI)SQL (DBeaver)basic MongoDB queriesSentryKibanaCharles ProxyGitCypressTypescriptLanguage proficiencyIntermediate EnglishBeginner SpanishNative RussianEmploymentEmploymentFull, Part-time, Project-basedWork formatRemoteWork scheduleFlexible, Shift, 5/2RelocationNot possibleBusiness tripsBusiness trips possibleArbiHunterAbout the companyPublic APIMedia KitNEWSupportTerms of ServicePrivacy PolicyMoreSearch for employeesPublish a vacancyMobile appFor all questions[контакт скрыт]© 2026 All rights reservedPrivacy Policy
