My toolkit: JMeter, LoadRunner \(TruClient, DevWeb, Web HTTP/HTML\), Selenium, pytest, AppInsights, Dynatrace, Azure DevOps\. I work across REST APIs, microservices, and cloud architectures \- not just running tests, but understanding why systems fail under pressure and driving the fix\. What sets me apart: I don't just test products\. I build them\. Won the Achiever Extraordinaire Award \- EY GDS's highest recognition \- for building an AI\-powered Resume Builder deployed company\-wide using LLM\-based prompt engineering\. Two other full\-stack projects live on GitHub\. Promoted to Consultant in 17 months\. ISTQB certified, Azure Data Scientist Associate, GitHub Copilot certified\.
