United StatesWhat I'm looking for
I’m a Test Engineer with 8 + years of Quality Engineering experience in Web and Mobile Applications testing across large enterprise environments and smaller teams. I’ve led mission-critical system testing with requirement analysis, test design, development, and product integration testing—often using causal analysis to resolve complex technical and process issues. I also write clear test specifications grounded in requirements and documentation.
I’m expert in manual testing (Black- and White-box) and Accessibility Testing (WCAG), and I build automation frameworks with Selenium and Appium. For API and backend validation, I use Postman (and Swagger), plus SQL for database validation and end-to-end testing using JSON. I’ve also owned data backup and restore reliability with Veeam, and I stay effective across Agile and Waterfall by collaborating cross-functionally and keeping test case tracking tight in Jira/Zephyr and TestRail.
