With over 13 years of experience and 14,000+ hours on Upwork, I create Ruby on Rails web applications that are not only functional but built to last. Able to take a project at any stage — from an initial idea to a complex, production-ready system — and manage every aspect: backend architecture, integrations, performance optimization, and long-term maintenance. I have successfully delivered large-scale projects across multiple domains — from a hotel booking engine to a fintech platform for investors, a job search and recruitment platform and many others. I leverage modern tools such as GitHub Copilot for documentation, autocomplete, code optimization, and SQL query improvements, while using AI assistants like ChatGPT and Gemini to speed up research and handle small tasks such as generating regular expressions. I also understand the importance of AI in boosting development speed, productivity, and automation, and apply it thoughtfully to enhance my workflow without compromising code quality. Whether you need to launch a new product, rescue a struggling codebase, or scale your existing platform, I bring the skills, reliability, and insight to get it done right the first time.

I build test automation that actually works in real projects, from writing Playwright tests to scaling them into stable E2E systems. I’m a Senior / Lead QA Automation Engineer with 7+ years of hands-on experience in UI and API automation. I write and maintain test suites, but also help teams structure QA, stabilize pipelines, and make testing a reliable part of delivery instead of a bottleneck. As a QA Lead, I’ve guided QA direction on projects, mentored engineers, and helped shape automation strategy from the ground up to production-ready coverage. I work closely with developers, PMs, and stakeholders, so I can both implement automation and take ownership of quality when needed. Most often, clients come to me, when automation doesn’t scale: regression takes too long, tests are unstable, or QA ownership is unclear. In those cases, I focus on making testing practical, maintainable, and aligned with real user behavior. Core stack: - Automation: TypeScript, JavaScript, Playwright, Cypress, Selenium, Webdriver, Appium, Cucumber, API testing - CI/CD & Infrastructure: Jenkins, AWS, Docker, GitHub Actions, GitHub, Bitbucket, GitLab - Data: MySQL, PostgreSQL, GraphQL I also have experience testing AI-driven features, including output validation, edge case handling, and ensuring consistent behavior across different inputs. I actively use AI-assisted tools like Cursor, Claude Code to speed up test development, debugging, and refactoring in real workflows. If you need someone who can write reliable automation, scale it when needed, and take ownership of QA - I’m ready to help.
