A top-performing certified QA engineer, I help startups and product teams ship with confidence — not just by catching critical bugs before your users do, but by building the QA processes that keep quality high long after launch. Whether you need hands-on testing today or a complete QA process set up from scratch, I deliver both. **📜 Certifications:** - ISTQB Certified: Foundation | Agile Tester | Mobile Tester | Test Analyst - Katalon Certified Expert **🏗 QA Process Building — From Zero to a Working Quality System:** Many teams have no QA structure at all — testing is ad-hoc, bugs slip through, and releases feel risky. I fix that by designing and implementing QA processes tailored to your team: - Assessing your current workflow and identifying quality gaps - Defining test strategy, coverage standards & release criteria - Setting up bug tracking, test documentation & reporting workflows (JIRA, Trello) - Integrating QA into your Agile sprints and CI/CD pipeline - Establishing regression and smoke test suites your team can rely on - Documenting everything so the process outlives any single tester The result: predictable releases, fewer production bugs, and a QA workflow your whole team actually follows. **🔍 What I Deliver Day-to-Day:** ✅ Web, Mobile (iOS & Android) & Desktop app testing ✅ Functional, Regression, Integration, Exploratory & Usability testing ✅ Cross-browser & cross-device testing (BrowserStack) ✅ API testing (Postman, Insomnia) ✅ Clear test plans, test cases & actionable bug reports your devs will thank you for **🤖 Test Automation — Playwright & Katalon Studio:** I build and maintain scalable automation frameworks that cut testing cycles and catch regressions early: - Web UI automation (Playwright, Katalon) - API test automation - Regression suites with CI/CD integration **🧠 AI-Enhanced QA — Automating the Full Testing Workflow:** I go beyond using AI as a helper — I build custom AI skills and workflows with Claude that automate most of the QA process end-to-end: - Turning manual tickets into structured test cases and executing them faster - Generating test scenarios and edge cases with broader coverage - Converting validated manual tests into production-ready automation scripts (Playwright, Katalon) - Integrating Claude with your tools via MCPs (JIRA, test management, CI/CD) so testing, reporting & ticket updates flow automatically The result: a QA pipeline where AI handles the repetitive work and human expertise focuses on what matters. **🛠 Toolbox:** Playwright, Katalon Studio, Postman, Insomnia, JIRA, Trello, BrowserStack, Proxyman, Bugzilla, Claude AI (Skills & MCP integrations) **💡 Why Clients Trust Me:** - ⭐ Top Rated Plus with a proven track record on Upwork - Fast turnaround, clear communication, detailed reporting - I find what others miss — and build processes that prevent bugs, not just find them Need someone to test your product today and build a QA system that scales with you tomorrow?

I help startups, SaaS companies, and growing businesses identify critical security vulnerabilities before attackers can exploit them. With 7+ years of experience in penetration testing and offensive security, I specialize in assessing web applications, APIs, mobile applications, and cloud environments and delivering clear, developer-friendly remediation guidance. My goal is simple: find the vulnerabilities that matter, explain the real business risk, and help your development team fix them properly. 🔐 PENETRATION TESTING SERVICES • Web Application Penetration Testing • API Security Testing • Mobile Application Security Testing • Cloud Security Assessments • Vulnerability Assessment • OWASP Top 10 Security Testing • Authentication & Authorization Testing • Business Logic Testing • Security Misconfiguration Testing • Manual Vulnerability Verification • Security Retesting & Remediation Validation 🛡️ WEB APPLICATION SECURITY I test web applications for vulnerabilities including: • SQL Injection • Cross-Site Scripting (XSS) • CSRF • SSRF • Broken Access Control • IDOR • Authentication weaknesses • Session management issues • File upload vulnerabilities • Security misconfigurations • Business logic flaws • Sensitive data exposure 🔌 API SECURITY Security testing for REST, GraphQL, and other API-based applications, including: • Broken Object Level Authorization • Authentication vulnerabilities • Authorization flaws • Excessive data exposure • Injection vulnerabilities • Rate-limit issues • API misconfigurations • Token and session security • Business logic vulnerabilities 📱 MOBILE APPLICATION SECURITY Security assessment of iOS and Android applications covering: • Insecure local storage • Weak authentication • API exposure • Sensitive data leakage • Application configuration issues • Reverse engineering risks • Client-side security weaknesses ☁️ CLOUD SECURITY Security reviews for cloud environments including AWS, Azure, and GCP, focusing on: • Access control • IAM configuration • Publicly exposed services • Storage permissions • Secrets and credentials • Security groups • Misconfigurations • Excessive privileges 📄 WHAT YOU RECEIVE Every assessment includes clear documentation designed for both technical and non-technical stakeholders. You receive: ✓ Executive security summary ✓ Verified vulnerability findings ✓ Severity and risk prioritization ✓ Reproduction steps ✓ Evidence and technical details ✓ Business impact explanation ✓ Developer-friendly remediation guidance ✓ Retesting support when required I prioritize manual security testing rather than relying entirely on automated vulnerability scanners. Automated tools can assist discovery, but vulnerabilities are manually validated to reduce false positives and identify logic flaws automated scanners frequently miss. 🏆 EXPERIENCE • 7+ years in penetration testing and application security • Security assessments across web, API, mobile, and cloud environments • Experience working with development and Agile teams • Developer-friendly vulnerability reporting and remediation support • Security testing for applications handling sensitive business and customer data 📜 CERTIFICATIONS • OSCP – Offensive Security Certified Professional • CEH – Certified Ethical Hacker • CompTIA Security+ WHY WORK WITH ME? ✓ Manual-first penetration testing ✓ Clear and actionable security reports ✓ Business-risk-focused vulnerability prioritization ✓ Confidential handling of sensitive information ✓ Clear communication throughout the assessment ✓ Practical remediation guidance for developers ✓ Retesting support after fixes Security testing should do more than generate a long vulnerability report. It should help you understand what can actually be exploited, what needs to be fixed first, and how to reduce your real security risk. If you need a penetration test, security assessment, vulnerability review, or independent security validation before launch, send me your project details and I’ll recommend the appropriate testing approach.
