SUMMARY
QA Automation Engineer with over 6 years of specialized experience in test automation and software
development. Expert in building robust automation frameworks and managing the Full-Cycle QA for
web applications and APIs. I leverage deep knowledge of BDD (Behavior-Driven Development),
Story Mapping, and Documentation as Code to facilitate seamless collaboration between
development teams and business stakeholders. My technical stack includes Selenium, Playwright,
Postman, SpecFlow, k6, enabling me to drive product quality and accelerate development cycles.

SKILLS:

●​ Analytical Excellence: Meticulous attention to detail with advanced skills in deep-dive analysis
and technical documentation.
●​ Test Automation Expertise: Comprehensive knowledge of testing types and methods using a
modern stack (Playwright, SpecFlow, Selenium, Appium, k6) across the entire SDLC.
●​ Architectural Knowledge: Deep understanding of containerized environments (Docker),
client-server models, and web application architecture.
●​ Polyglot Programming & Data: Multi-language proficiency including C++, C#, PHP, Python,
and JavaScript, complemented by strong database (PostgreSQL) design and querying skills.
●​ AI-Driven Development: Expert at leveraging AI-powered tools to optimize QA processes and
increase team productivity.
●​ Mentorship:Experienced in providing technical guidance and fostering a collaborative
environment within cross-functional teams.
