## PROFESSIONAL SUMMARY
For over 10 years, I've been the silent guardian of software excellence. My journey began in the trenches of software quality assurance, where I mastered the art of turning "it works" into "it works flawlessly." From stress-testing code for agile Silicon Valley startups, I've honed a meticulous eye for detail and a passion for bridging technical robustness with real-world user needs.

In the early days, I lived by the mantra: "A bug unresolved today becomes a crisis tomorrow." This mindset drove me to architect testing frameworks for applications across industries like education, healthcare, transportation and logistics—ensuring not just functionality, but scalability, stability, and compliance. But technology never sleeps, and neither do I.

When Agile disrupted traditional QA, I immersed myself in CI/CD pipelines and automation tools like Selenium and Cypress and Playwright. Earned certifications in cloud technologies and data analytics to stay ahead of shifting industry demands.

My focus today is on AI's transformative potential - learning about models, exploring AI agents, and stress-testing conversational AI chatbots, including penetration testing AI tools to detect vulnerabilities. My QA roots now fuel a new mission: ensuring AI systems are ethical, reliable, and human-centric.
