Hi there! 👋 Are you looking to transform your QA process from a final "checkpoint" into a strategic business advantage? I am a QA Automation Strategist specializing in the 2025-2026 shift toward Agentic AI and Shift-Right testing. I help teams reduce customer-reported defects by building resilient, automated frameworks that prioritize ROI and faster release cycles. Whether you need to migrate legacy Selenium suites to Playwright (the new industry favorite) or implement a comprehensive CI/CD testing gate, I provide end-to-end solutions. My approach focuses on "Designing for Testability," ensuring your code is modular, maintainable, and ready for high-scale automation. Services Offered: • Framework Development: Custom, scalable frameworks using Playwright, and Selenium. • AI Integration: Implementing AI-driven test creation and autonomous failure diagnosis. • Comprehensive Testing Suites: API (Postman), and Performance (JMeter) testing. • Strategy & Management: Full test management via TestRail, including risk analysis and test case prioritization. • DevOps/SRE Collaboration: Embedding automated canary releases and chaos testing into your pipeline. Core Skills: • Languages: JavaScript, TypeScript, C#, Java. • Platforms: Web, Mobile (iOS/Android), and Desktop. • Methodologies: Agile, BDD, TDD, and DevOps. Analogy for Understanding: Think of QA Automation like an automated home security system. Manual testing is like a security guard walking the perimeter - essential for spotting unusual, human-level subtleties (exploratory testing). However, QA Automation is the network of sensors and AI-powered cameras that monitor every entry point 24/7 without getting tired, catching predictable threats instantly and allowing the "guard" to focus on high-level strategy rather than just watching the door.

I help SaaS and healthcare tech teams ship reliable software faster with automation frameworks that actually hold up in production. With 7+ years in QA across web, mobile, and API and an ISTQB® Certification (CTFL). I've worked in regulated environments where a missed bug isn't just a bad review, it's a compliance risk or a revenue loss. What makes my work different: I've tested AI-driven systems including voice assistants, conversational flows and agent behavior covering edge cases, prompt manipulation and real-world failure scenarios. I've delivered in healthcare and fintech environments where accuracy and compliance are non-negotiable. My test suites consistently reduce manual regression by 70–90%. I can help you: Build Playwright or Selenium frameworks from scratch Stabilize flaky tests and improve pipeline reliability Convert manual test cases into scalable automation Test AI agents, LLM outputs and automated workflows Cover critical user flows, APIs, and edge cases end to end Tech Stack: Playwright • Selenium • Cypress • Appium • REST Assured • TypeScript • Java CI/CD: GitHub Actions • Jenkins • Docker If your team is shipping fast and quality is getting harder to maintain that's exactly where I work best.
