Quality Assurance & Manual Testing Specialist As a meticulous Manual Testing professional with a background in Technical Support and Design, I offer a unique, user-centric approach to software quality. My experience spans from technical troubleshooting for telecommunications to specialized QA freelancing for gaming platforms. I bridge the gap between technical functionality and aesthetic integrity, ensuring that every product I test is not only functional but intuitive. I provide comprehensive Manual Testing services designed to identify critical bugs and optimize the user experience before your product reaches the market. My methodology is rooted in a deep understanding of the software development lifecycle and a "think-like-the-user" mentality.

What's included

Core Testing Competencies
I utilize a diverse range of testing methodologies to ensure full coverage of your application: User Acceptance Testing (UAT): I validate that the end-to-end business flow meets your specific requirements, drawing from my experience in game UAT and responsiveness testing. Regression Testing: I perform rigorous checks after updates to ensure that new code changes haven't negatively impacted existing features. Exploratory Testing: Using an unscripted, intuitive approach, I investigate the application to find edge-case bugs that structured test cases might miss. Usability Testing: Leveraging my background in Figma and wireframing, I evaluate the "feel" of your UI/UX, ensuring the design is accessible and user-friendly. Black Box Testing: I examine the functionality of your software without peering into its internal structures, focusing purely on inputs and outputs from the user's perspective. Sanity Testing: I conduct quick, focused evaluations of specific functional areas after bug fixes to verify that the logic is sound before proceeding to wider testing. Why Choose My Services? Detail-Oriented & Critical: My transition from Technical Support to QA has honed my ability to analyze complex problems and catch minute errors that others might overlook. Whether it's a repetitive task or a high-level design critique, I remain critical of every element to ensure a polished final product. Effective Communication: 16 months of experience in support roles means I can translate technical bugs into clear, actionable reports for your development team. Design-First Mindset: Because I design websites and marketing materials myself, I don't just find functional bugs—I find "design bugs" that affect your brand's credibility. Multi-Platform Experience: From web applications to mobile responsiveness and gaming, I adapt my testing strategy to the specific platform and audience.
FAQs
I provide specialized Manual Testing by stepping into the shoes of your end-user. My goal is to simulate real-world usage to identify friction points and ensure the final product is seamless, functional, and ready for your audience.
I conduct all tests on physical devices to ensure a 100% authentic User Acceptance Testing experience. I do not use emulators; I test exactly how your customers interact with your product. PC / Desktop (Web Testing): Windows 10 Browsers: Chrome, Microsoft Edge Mobile (App & Responsiveness Testing): Device: [Samsung Galaxy A36] Testing Focus: Touch targets, screen rotation, and mobile-specific Exploratory Testing.
