Architected a multi-role coaching platform with a React/Vite frontend and role-based access control for 3 client tiers, then built a secure Express.js backend. Implemented JWT authentication, request rate limiting, and Stripe payment pathways across 10+ server routes, plus WebSockets for real-time notifications that improved order update speed by 40%.

Built a modular Playwright Java Page Object Model (POM) with advanced data-driven login scenarios, extracting 25+ test-data matrices from Excel via Apache POI. Reduced flaky failures by 20% using smart waits and isolated browser contexts, and automated HTML regression report publishing through GitHub Actions on every 100% source update.

Led a 4-person Scrum team to manage 9+ bugs end-to-end and delivered a comprehensive 9-class Selenium test suite achieving 92% overall coverage for core Authentication, Shopping, and Account workflows. Implemented Apache POI data-driven testing (60+ variants) and used GitHub Actions to run parallel tests, reducing execution time by 35%, while authoring SRS, test plans, test cases, and an RTM.

Developed a headless backend API testing architecture covering 15+ REST endpoints and validated data persistence, strict payload structure, authentication status, and 100% standard HTTP response codes. Used Postman collections to verify schemas and run negative tests across 30+ edge cases, and conducted security testing to identify and document 4 endpoint vulnerabilities.

Designed and executed 100+ manual test cases for core HR modules (recruitment, leave, performance) and created 40+ high-fidelity bug reports with clear reproduction steps, environment parameters, and expected vs. actual results. Maintained project test plans and ensured 100% requirement traceability matrix completion with active execution cycles.

Completed a Quality Assurance Engineer Certificate program with an intensive 500+ hour focus on manual, back-end, and API testing, including automation using Selenium.

Pursuing a B.Sc. in Computer Engineering with coursework including Data Structures & Algorithms, Database Management, Software Architecture, and Cybersecurity Principles.
