As a Certified IT Professional (B.Sc Hons), I specialize in the Quality Assurance of complex business logic and web systems. My background in System Development allows me to go beyond surface-level testing; I analyze the root cause of bugs using browser console logs, API responses, and database queries. Key Contributions: ✔️University Management System: Led the QA for a comprehensive student portal, identifying critical logic errors in grade calculation and enrollment modules prior to launch. ✔️E-Commerce Website Builders: Validated the core functionality of dynamic page builders, ensuring that drag-and-drop modules, custom product layouts, and third-party integrations (Payment/Shipping) functioned seamlessly across all devices. ✔️Shop Order Management Systems: Conducted rigorous stress testing for order processing workflows, ensuring 100% accuracy in inventory deduction and database updates. ✔️Expense Tracking Applications: Performed security and functional audits on financial tools, ensuring data precision and user privacy. My QA Methodology: ✔️Deep-Dive Analysis: I don't just report "it's broken." I report where it broke (Frontend vs. Backend). ✔️User-Centric Testing: I test edge cases that real users encounter but developers often miss. ✔️Tools: Jira, Trello, Postman (API), Chrome DevTools, Selenium (Basics).
