About

Results-driven SDET with 4+ years of experience designing and scaling automation frameworks for complex B2B platforms. I specialize in Java-based UI and API automation using Selenium, Playwright, and Rest Assured — with a strong track record of reducing regression execution time by up to 80% and improving backend validation accuracy by 60%. 🔹 What I bring to the table: • Built end-to-end UI automation suites from scratch for B2B portals (Backoffice, NP Portal, API Portal) using Java + Selenium and Playwright • Delivered 200+ API test cases across REST, SOAP, and AWS Lambda services using Rest Assured + Cucumber • Engineered a custom API comparison framework that cut response discrepancy detection time by 60% • Integrated automation with CI/CD pipelines via GitHub Actions + Selenium Grid for parallel distributed execution • Validated large-scale platform migrations — SQL to AWS Cognito auth systems, Cloudflare domain migrations, and service endpoint transitions • Built observability infrastructure: Grafana dashboards, CloudWatch queries, and Allure reports for proactive issue detection (40% faster debugging) • Performance testing experience with K6 and JMeter 🔹 Core Stack: Java | Selenium | Playwright | Rest Assured | Cucumber | TestNG | GitHub Actions | Selenium Grid | AWS (Lambda, Cognito, CloudWatch) | Postman | JIRA | Grafana | K6 | JMeter | Python I'm passionate about automation scalability, shift-left testing, and DevOps-driven quality.
