Playwright/TypeScript Test Automation
Expertise in designing and building Playwright/TypeScript frameworks that cover broad regression across distributed microservices, including Selenium-to-Playwright migration prioritized by business risk, stability, and execution value.
UI & API Automation
Comprehensive experience in UI and API automation using REST, GraphQL, Postman, Bruno, and Swagger/OpenAPI, with scalable frameworks built for CI-driven regression coverage across enterprise SaaS and distributed systems.
CI/CD Quality Gates
Proficient in integrating automated test suites into CI/CD pipelines with Azure DevOps, GitHub Actions, GitLab CI/CD, and Jenkins, using parallel execution strategies to significantly reduce CI feedback time.
BDD with Gherkin/Cucumber
Authoring of business-readable BDD scenarios in Gherkin, aligning automated coverage with product owner and business analyst requirements across regulated and enterprise environments.
Data Validation & SQL
Validation of data integrity for critical business flows using PostgreSQL and MySQL queries in DBeaver, ensuring accurate test outcomes across financial and pharmaceutical platforms.
Diagnostics & Reporting
Diagnosis of failures across UI, API, application logs, and database state using Playwright Trace Viewer, AWS CloudWatch Logs, Allure, and Browser DevTools/Network Analysis.
AI-Assisted Test Engineering
Acceleration of test authoring using GitHub Copilot, Claude, ChatGPT, and Microsoft Copilot while retaining full engineering review and quality standards.
Test Strategy & Architecture
Define and execute test strategies for web and desktop platforms, including smoke, critical-path, and scheduled regression suites, using state-based synchronization instead of fixed waits.
Cloud & Containerization (QA)
Experience with AWS (QA), Docker, and cloud-hosted test artifacts, including traces, videos, and reports for distributed system testing.
Selenium & Python Automation
Building Selenium/Python automation frameworks for financial services platforms, increasing automation coverage, and reducing regression cycle duration significantly.

Project history
Designed and built a Playwright/TypeScript framework covering approximately 80% of regression across distributed microservices in pharmaceutical (regulated) and retail e-commerce enterprise platforms. Reduced CI feedback time by approximately 35% through parallel execution in Azure DevOps pipelines. Diagnosed failures across UI, API, application logs, and database state using Playwright Trace Viewer, AWS-hosted test artifacts, CloudWatch logs, and SQL validation. Authored BDD scenarios in Gherkin, accelerated test authoring by approximately 40% using GitHub Copilot and Claude, and validated data integrity for 100+ critical business flows using PostgreSQL/MySQL queries in DBeaver.
Led migration from Selenium to Playwright/TypeScript on a threat intelligence SaaS platform, prioritized by business risk, stability, and execution value. Built a scalable UI/API automation framework for CI-driven regression coverage. Structured suites into smoke, critical-path, and scheduled regression runs. Reduced test flakiness from approximately 30% to below 5% and maintained a CI pass rate above 95%, reducing manual regression effort by approximately 60%. Evaluated Cypress/TypeScript during stack assessment.
Led QA and defined test strategy across web and desktop for a cross-platform synchronization product, including compatibility coverage across supported platforms and versions. Worked as a B2B contractor and relocated to Slovakia during the engagement.
