๐ ๏ธQA Engineer | Manual & Automated Testing | API Testing (Postman)
I am a QA Engineer with 7+ years of experience in software testing. I have strong skills in both manual and automated testing. I cover PSTโEST well.
๐In QA, I have worked with tools like Katalon and Tosca and created 500+ automated test cases.

A Senior QA Engineer with 10+ years of experience testing SaaS, enterprise web apps, APIs, desktop apps, and mobile products at companies like Workday, Cisco, Intel, Thinkific, and CyberQP.
I specialize in finding the bugs that usually escape basic test cases: permission issues, broken edge cases, data mismatches, workflow gaps, integration failures, flaky UI behavior, and release-blocking regressions.
My strength is not just testing screens. I understand how modern SaaS products work: multi-tenant environments, role-based access, APIs, dashboards, session handling, backend/frontend boundaries, CI/CD pipelines, and customer-facing workflows.

I am a Computer Science Engineer with a postgraduate diploma in Network Security and 5+ years of hands-on experience delivering quality assurance across real-world systems including web apps, SaaS platforms, hardware-integrated products, and network-centric environments.
I have tested products end-to-end before production releases, identifying functional, usability, data-flow, and edge-case issues early to reduce release risk and improve system stability and user experience.
What I have Done & Delivered
1. Tested web and SaaS applications across browsers, admin dashboards, and configuration-heavy interfaces, helping teams catch usability and workflow issues before customer impact
2. Performed manual, exploratory, regression, and UI/UX testing, uncovering edge cases that scripted tests often miss
3. Created clear, reusable test plans and test cases, improving test coverage and repeatability across release cycles
4. Logged high-quality bug reports with clear repro steps, severity, logs, and visualsโreducing back-and-forth with developers
Automation, Playwright & Collaboration
1. Built and maintained Playwright (TypeScript) automation for critical user flows and regression scenarios
2. Used GitHub for version control, structured commits, and collaboration with engineering teams
3. Applied judgment on when automation adds value vs. when manual testing is more effective, keeping test suites reliable and meaningful
API, Network & Security-Focused Testing
1. Tested REST APIs using Postman, validating status codes, payloads, negative scenarios, and error handling
2. Applied a network-security mindset (TCP/IP, DNS, DHCP, VLANs, ports, traffic flow) to identify misconfigurations and stability risks
3. Performed basic application security testing aligned with OWASP Top 10, focusing on risk rather than noise
Hardware, System & Device Validation
1. Tested encoder/decoder platforms, firmware, and device WebUIs in hardware-integrated environments
2. Validated firmware upgrades/downgrades across Alpha, Beta, and production releases
3. Verified system behavior involving authentication, networking, and live data flows
How Clients Describe My Work
1. Detail-oriented, investigative, and process-driven
2. Clear communicator with developers, product owners, and stakeholders
3. Reliable, security-conscious, and focused on real-world usageโnot just happy paths
Tools & Tech
1. Playwright (TypeScript), GitHub, Jira, TestRail, Postman, Wireshark, Python (test logic & validation), Agile/Scrum, CI/CD awareness
Engagement Model
I am open to freelance and hourly work and typically start with a small trial (~10 hours/week) to ensure a strong fit. Hours can scale based on results and project needs.
