Building a website or app for a client and need someone to make sure it actually works before launch?
I help agencies and development teams test client products manually, find functional issues, and catch bugs before they reach the end user.
I focus on real-world QA, not just checking whether a button works. I test user flows, edge cases, integrations, responsiveness, usability, and API behavior so your team can ship with confidence.
๐ Problems I Help You Catch
Broken or inconsistent user flows
Functional bugs and unexpected behavior
Issues across browsers, devices, and screen sizes
API request/response problems
Form, authentication, payment, and integration issues
Usability and UX problems that affect the user journey
Regression issues after new features or fixes
Bugs that are difficult for developers to reproduce
โ What I Do
Manual & Functional QA Testing
Website & Web Application Testing
Mobile Application Testing
User Acceptance Testing (UAT)
End-to-End Testing
Usability Testing
Regression Testing
Cross-Browser & Cross-Device Testing
API Testing
Bug Reporting & Documentation
Test Case & Test Scenario Creation
Test Management & QA Documentation
๐งช My Testing Approach
I test from both the business and end-user perspective.
I don't just look for obvious bugs. I follow actual user journeys, test different scenarios and edge cases, verify expected behavior, and document issues clearly so developers can reproduce and fix them quickly.
My workflow typically includes:
Requirements โ Test Scenarios โ Functional Testing โ Edge Cases โ Cross-Browser/Device Testing โ API Validation โ Bug Documentation โ Regression Testing โ Final QA
๐ Tools I Work With
Jira โ bug tracking & project management
Zephyr โ test case & test management
Postman โ API testing
Insomnia โ API testing
BrowserStack โ cross-browser & cross-device testing
Charles Proxy โ network/debugging analysis
๐ What You'll Get
โ Clear, reproducible bug reports
โ Screenshots and screen recordings when needed
โ Steps to reproduce
โ Expected vs. actual results
โ Severity / priority identification
โ Test cases and test scenarios
โ Regression testing after fixes
โ QA feedback from a real user's perspective
๐ค Ideal for Agencies
If you're an agency building websites, web applications, or mobile products for clients, I can work alongside your development team as a dedicated QA layer.
You build it.
I test it.
Your client gets a product that's ready to launch.
I bring professional QA experience with a practical, detail-oriented approach focused on finding issues before your client does.
๐ Hook Offer
Want to see how I approach your product before committing to a larger QA engagement?
Send me your website, app, or test environment and I'll provide a free QA sample/audit highlighting a few issues or improvement opportunities I identify.
If you're looking for a reliable Manual QA Tester, Functional Tester, or Software QA Tester for your agency's client projects, send me a message and let's get started.

๐ Most QA engineers find bugs. I find the ones that cost you money.
With 5+ years testing web, mobile, and desktop applications across Fintech, E-Commerce, SaaS, and Healthcare, I specialize in two things: making sure your app works โ and making sure it holds up when real users hit it at scale.
โ๏ธ I combine rigorous manual testing with performance testing (JMeter, k6) to catch what unit tests miss: the race conditions, load-breaking bottlenecks, and edge cases that only appear in production. My clients don't find out about critical bugs from their customers โ they find out from me, first.
โ Functional & regression testing across web, mobile (iOS/Android), and desktop
๐ Performance & load testing to validate your app survives real-world traffic
๐ก๏ธ Industry-specific risk awareness: compliance, data integrity, payment flows
๐ Clear bug reports with reproduction steps, severity tagging, and fix suggestions
๐ผ Experience in Fintech, E-Commerce, SaaS, and Healthcare โ I know the high-stakes scenarios
โ ๏ธ If your product handles transactions, patient data, or high-traffic commerce โ a crash isn't just an inconvenience. It's a crisis. Let's make sure it never gets there.
๐ฉ Open to hourly engagements, project-based testing sprints, and ongoing QA retainers. Message me with your tech stack and I'll tell you exactly how I'd approach it.
