Job Success
Dubai, United Arab Emirates - 3:30 am local time
I’m a QA Engineer and Cybersecurity expert with 100% Job Success Score and 15+ years of experience across SaaS and CRM platforms, mobile applications, POS systems, fintech, healthcare, and e-commerce.
I help web, mobile, and API teams find bugs, vulnerabilities, and usability issues before their users or attackers do.
My approach combines Quality Assurance with security-focused testing. I validate products against requirements, test them through real-user scenarios, and identify functional defects, security weaknesses, payment issues, API problems, and UX friction before they reach production.
On a recent mobile project, I identified 100+ bugs before release, helping the application launch with zero critical issues.
What I Work On:
✅ Manual QA & Functional Testing
I thoroughly test applications across critical user journeys, business requirements, edge cases, and real-world scenarios.
* Manual QA Testing
* Functional Testing
* Regression Testing
* Exploratory Testing
* End-to-End Testing
* Smoke & Sanity Testing
* User Acceptance Testing
* Test Case Design
* Cross-Browser Testing
* Responsive Testing
✅ Playwright Test Automation
I build maintainable automation suites that reduce repetitive manual regression work and help teams release faster.
* Playwright + TypeScript
* JavaScript Test Automation
* End-to-End Automation
* Cucumber / BDD
* Automated Regression Suites
* Cross-Browser Automation
* GitHub Actions CI/CD Integration
* Reusable Test Frameworks
✅ Cybersecurity & Application Security
Modern products need more than functional testing. I help identify security weaknesses and reduce risk across web applications, APIs, networks, and infrastructure.
* Web Application Security Testing
* OWASP Top 10 Assessment & Mitigation
* API Security Testing
* Authentication & Authorization Testing
* Vulnerability Assessment
* Penetration Testing
* Vulnerability Assessment & Penetration Testing (VAPT)
* Security Audits & Risk Analysis
* Access Control Testing
* Security Configuration Review
✅ Network & Infrastructure Security
I help assess infrastructure security and identify weaknesses that could increase exposure to cyber threats.
* Network Security Assessment
* Firewall Security Review
* IDS/IPS Review
* Network Segmentation
* Secure Configuration Review
* Endpoint Security
* Access Control
* Security Hardening
* Infrastructure Risk Assessment
✅ Threat Monitoring & Security Operations
Security requires continuous visibility, not just one-time testing.
* Log Monitoring
* Threat Detection
* Security Event Analysis
* Incident Response Support
* Risk Identification
* Security Policy Development
* Security Best Practices Implementation
* Preventive Security Recommendations
✅ API & Database Testing
I validate APIs, integrations, databases, and backend workflows from both functional and security perspectives.
* Postman API Testing
* REST API Validation
* Endpoint & Response Testing
* API Integration Testing
* Error Handling Validation
* Webhook Testing
* SQL Data Verification
* MySQL & PostgreSQL
* API Security Validation
✅ Mobile App Testing
* iOS Testing via TestFlight
* Android App Testing
* Play Store Closed Testing
* Real Device Testing
* Android Emulator Testing
* Mobile Web Testing
* Cross-Device Testing
* Responsive UI Validation
✅ SaaS, Website & E-Commerce QA
* Registration & Login
* User Onboarding
* Checkout & Shopping Cart
* SaaS Dashboards
* Admin Panels
* Role & Permission Testing
* Subscription Workflows
* CRM Workflows
* E-Commerce User Journeys
✅ UX & Usability Testing
A feature can technically work and still frustrate users. I identify friction that traditional functional testing can miss.
* First-Time User Experience
* Registration & Onboarding Friction
* Checkout & Payment Drop-Off Analysis
* Navigation & Information Clarity
* Error Messages & Empty States
* UI Consistency
* Figma Design Validation
* UX Improvement Recommendations
I don’t just check whether a feature works.
I test whether it works correctly, remains secure, handles real-world scenarios, and delivers a reliable user experience.
If you’re building a web application, mobile app, SaaS platform, API, fintech product, or e-commerce system, I can help you identify bugs, security weaknesses, and UX problems before they impact your users or your business.
