Over the last 8+ years, I've worked with startups, agencies, and enterprise teams across 36 Upwork projects, testing Web, Mobile, SaaS, Fintech, Shopify, E-commerce, and AI applications.
Most of my work has involved Manual QA, with Playwright Automation becoming part of the process on projects that required reliable regression testing and CI/CD integration.
Alongside Manual QA, I've built and maintained Playwright Automation suites integrated with CI/CD pipelines to improve regression coverage and release confidence. One of my recent projects involved Chick-fil-A, where I worked with Playwright and Zypherscale to support a faster and more reliable release process.
I've also worked on Shopify stores, including Freshland, Dream Controller, and Dyeport, validating checkout flows, payment gateways, order management, discounts, and customer journeys. My experience also includes mobile applications such as Etnowe and Simba, along with AI products like MyMood AI, where testing focused on workflow validation, usability, response quality, and real-world user behavior.
Testing isn't just about executing test cases. Every product has different risks, release cycles, and business priorities. My approach is to understand the product first, identify the areas that carry the highest risk, and apply the right balance of Manual Testing and Automation Testing to deliver reliable releases with confidence.

🚀 Transforming QA from a Bottleneck into a Business Advantage
As a detail-oriented QA Engineer, I help B2B SaaS, complex fintech platforms, and fast-moving mobile startups accelerate their delivery cycles without ever sacrificing quality. By taking absolute end-to-end ownership of the testing process, I minimize post-release business risks, prevent revenue-impacting bugs, and ensure your software ships quickly as a stable, production-ready product.
I understand that in Agile environments, speed is just as important as stability. My goal is to catch critical issues before they reach your customers, protecting your brand reputation and saving development time.
🔍 Comprehensive Quality Assurance: Manual & Automated
With over 5,000 hours of Software Testing experience across 30+ platforms, I operate effectively as both a meticulous manual QA Tester and a highly technical QA Automation specialist. I don’t just check if a feature works on the sunny-day paths; I simulate complex user flows, dig into unintuitive areas, and rigorously validate edge cases to ensure your system doesn't break under real-world pressure.
Whether I’m stepping in as an exploratory Tester or a strategic Automation Engineer, my approach guarantees a high-quality bar. I bridge the gap between user expectations and technical execution, providing a safety net for your engineering team.
My Core Testing Methodologies:
🧪 Functional & Exploratory Testing: Navigating the app like a real user to uncover non-obvious logical errors and UX friction points.
🔄 Thorough Regression Testing: Ensuring that new code merges never break existing, legacy functionality. Every Test phase I run is structured and methodical.
⚙️ API Validation: Going beyond the UI. I inspect network requests, validate JSON responses, and ensure flawless backend-to-frontend data integrity using tools like Postman and Chrome DevTools.
📱 Mobile Device Testing: Validating responsive design, cross-platform UI consistency, network interruptions, and memory scenarios on actual iOS and Android devices.
🛠️ Technical Stack & Frameworks
To provide maximum test coverage and efficiency, I build custom solutions and adapt quickly to your existing CI/CD pipelines.
UI & E2E Automation: I write robust custom scripts in Python and JavaScript (using Selenium WebDriver, Pytest) and am highly adaptable to modern testing frameworks like Cypress and Playwright.
Performance & Load: Using tools like Locust to stress-test your system, identify memory leaks, and verify infrastructure health under high concurrent loads.
API Testing: Advanced Postman collections, REST/GraphQL validation, and deep log inspection.
Management & Tracking: Mastery of Jira, Confluence, TestRail, and Hiptest for maintaining comprehensive test documentation.
📊 Proven Track Record & Project Ownership
I've led QA teams of 4–8 specialists and managed the full quality lifecycle for highly demanding applications, from MVPs to high-load enterprise platforms:
☁️ SaaS & Enterprise B2B: Acted as the lead QA and Automation Tester, building automated pipelines from the ground up. I verified complex business logic, role-based access controls, and data processing for logistics platforms and real estate CRMs.
📈 Fintech & Trading: Handled full-cycle quality assurance for a high-stakes trading platform. I designed and executed complex test scenarios where accuracy and system reliability were non-negotiable.
📱 Native & Cross-Platform Mobile: Executed deep mobile app testing across iOS (Swift/TestFlight) and Android. I handled everything from API integrations and rapid user interactions to validating core posting flows and location-based features.
🏥 Compliance & Healthcare: Performed detailed API and performance testing in a regulated environment where precision and clear documentation are mandatory.
🤝 Seamless Workflow & Clear Communication
I'm a strong believer that QA is a communication role as much as a technical one. I don't just wait for instructions — I act proactively.
📝 Actionable Bug Reports: I log defects directly in Jira with absolute clarity. My reports always include expected vs. actual results, severity ratings (Critical, Major, Minor), environment details, and exact, reproducible steps so your dev team doesn't have to guess or ask follow-up questions.
🗣️ Clear Communication: I collaborate closely with developers, product managers, and designers using clear written English to resolve ambiguities early in the sprint.
⚙️ Continuous Integration: I integrate a continuous feedback loop directly into your agile workflow to ensure stable mobile and web releases.
If you're looking for a proactive professional who can hit the ground running, take ownership of your quality standards, and deliver bulletproof results, I'm ready to join your team. Let's connect and build something exceptional together!

Most QA contractors show up, run some tests, and log tickets. I build the system that makes your whole team ship faster - and keeps it running long after the engagement ends.
I've spent 8+ years embedded in product teams - SaaS startups, scale-ups, fintech, healthtech, AI-first companies. I know what breaks at 3am before a release, what developers actually need in a bug report, and how to build automation that survives a codebase rewrite. ISTQB certified. 100% JSS. 7,500+ hours billed on Upwork without a single failed contract.
(✔️) Test automation - Playwright, Cypress, Selenium, REST Assured, k6
I build automation suites from scratch or layer them on top of existing code. Framework design, test architecture, CI/CD integration - the full picture, not just writing scripts. Every suite I deliver runs on every commit, gives your team fast feedback, and doesn't collapse the moment someone refactors a component. I've worked with GitHub Actions, GitLab CI, Jenkins, CircleCI. I write tests that are maintainable, not clever.
(✔️) AI product QA - LLM testing, hallucination detection, prompt regression
This is where most QA engineers hit a wall. Testing AI-powered products requires a completely different mindset - outputs are non-deterministic, edge cases are semantic, and traditional assertion logic breaks down fast. I've built QA pipelines for LLM-based features: output validation frameworks, hallucination detection heuristics, prompt regression suites that catch regressions across model versions, and end-to-end AI pipeline QA. If your product uses AI under the hood and you're not testing it systematically, you're shipping blind.
(✔️) API & backend testing - REST, GraphQL, SOAP
Full API test coverage: functional testing, contract testing, schema validation, error handling, edge cases, load and stress scenarios with k6. I test APIs as a first-class surface, not as an afterthought between UI tests.
(✔️) Mobile QA - React Native, iOS, Android
Real device testing and BrowserStack. I cover the full matrix - OS versions, screen sizes, network conditions, background/foreground behavior, push notifications, deep links. React Native is my primary mobile stack but I've tested native iOS and Android products as well.
(✔️) Accessibility - WCAG 2.2, ADA compliance
Accessibility audits built into the QA process from day one, not retrofitted before an App Store review or a legal notice. I test with screen readers, keyboard-only navigation, contrast analysis, and semantic markup review. I deliver remediation reports your dev team can act on directly.
(✔️) Test documentation & strategy
Test plans, test case design, traceability matrices, risk-based test strategy, coverage reports. I document QA processes so they outlive any single contractor - your team can pick up where I leave off without losing context.
(✔️) Manual & exploratory QA
Structured exploratory sessions, user flow testing, cross-browser and cross-device regression, edge case mapping, session-based test management. I don't just follow test cases - I think about how real users break things, and I document what I find in a way that's useful, not just a ticket dump.
Results from recent work:
- 30% reduction in post-release defects for an AI-powered SaaS platform after introducing structured QA process ownership and expanding automation coverage
- 20% faster release cycles by shifting testing left and eliminating manual bottlenecks in the regression phase
- 100% JSS maintained across 7,500+ hours billed across multiple long-term engagements
How I work:
Async-first, timezone-flexible, documentation-driven. I write bug reports developers can act on in minutes - reproduction steps, environment details, severity assessment, and root cause hypotheses when relevant. No ticket noise, no vague "it broke" reports.
I integrate cleanly with whatever you use: Linear, Jira, GitHub Issues, Notion, Confluence. I show up to standups prepared, I flag risks early, and I don't disappear between check-ins.
I'm available for ongoing retainers and fixed-scope projects. Greenfield automation builds, QA audits, AI testing strategy, mobile QA, accessibility reviews - if quality is the problem, let's figure out the right solution together.
