About

I am a Senior SDET & AQA Lead focused on building reliable, maintainable test automation and quality processes for web & mobile products. Over the last 8+ years, I have worked as a hands-on engineer and a lead, combining deep technical work (frameworks, CI/CD, performance) with mentoring and quality strategy for multiple teams.

My goal is to make releases predictable and safe: move critical checks into automation, integrate them into CI/CD, and align quality work with real business priorities instead of 'test coverage for its own sake'.

What I Do as a Senior SDET / AQA Lead

  • Design and evolve test automation architecture for web & mobile (UI, API, integration) using TypeScript/Node.js
  • Build and maintain automation frameworks with Playwright, WebdriverIO, Appium, Detox and Flutter integration tests
  • Integrate automated tests into CI/CD (GitLab, GitLab CI, Bitrise, AWS) to catch issues before production and make releases predictable
  • Define quality strategy and metrics together with engineering and product, focusing on business-critical user flows
  • Mentor QA/SDET engineers, set coding standards, code review practices and testing guidelines across teams
  • Collaborate with developers and DevOps on performance, reliability and observability improvements

Technologies I Work With

A modern tech stack powering enterprise-grade test automation and quality engineering

Core Stack

TypeScript / Node.js, Playwright, WebdriverIO, Appium, Detox, Flutter integration tests, REST APIs, CI/CD (GitLab, GitLab CI, Bitrise, AWS), Docker, Linux.

Also worked with: Cypress, Java/Selenide, performance and monitoring tools.

Enterprise E2E Automation Framework

Built enterprise test automation platform from scratch serving 20+ teams and 100+ engineers. Reduced regression cycle 90% (3 weeks → 3 days) saving $180k/year. Eliminated 80% of integration tests through contract testing while achieving 95% coverage.

The Challenge

The organization faced a critical challenge: multiple applications built with different technology stacks (React, Angular, Vue) had no unified testing approach. Each team maintained their own testing solutions, leading to inconsistent quality gates, duplicated efforts, and a 3-week regression cycle that was blocking rapid delivery.

The Solution

Architected a modular framework with TypeScript + Playwright as the core, supporting multiple test runners

For Hiring Managers

If you are looking for someone who can go beyond "writing tests" and take ownership of test automation, quality strategy and CI/CD integration, this is where I can help.

I work best in environments where:

  • Quality is treated as a shared responsibility, not just a QA task
  • There is room to improve automation architecture and processes, not only "add more tests"
  • Teams are ready to collaborate on making releases faster and safer at the same time
