I help businesses find bugs and usability issues before they affect their users. I test web applications, mobile apps, APIs, and payment flows from a real user's perspective. I focus on functional testing, user flows, edge cases, regression testing, cross-browser testing, and end-to-end scenarios. I also test APIs using Postman and Swagger and can cover payment gateways and critical transaction flows. For every confirmed issue, I provide clear steps to reproduce, expected vs. actual results, screenshots or screen recordings, and the relevant priority/severity. Testing Services • Manual & Functional Testing • Web & Website Testing • Mobile App Testing • API Testing - Postman & Swagger • Payment Gateway & Transaction Testing • Regression & Retesting • Exploratory Testing • End-to-End (E2E) Testing • Cross-Browser Testing • UI/UX Testing • UAT • Performance Testing Tools: Jira, Linear, Trello, Postman, Swagger, BrowserStack, Slack, and Notion. I don't just check whether a feature works. I look at how a real user would use it and where things can go wrong. If you have a website, app, API, or payment flow that needs testing, send me the details and I’ll help you define the right testing scope.

Need a reliable QA Engineer who can help you ship high-quality software with confidence? I have 7+ years of experience testing Web, Mobile (iOS & Android), Desktop, SaaS, and API-based applications. I specialize in manual testing, exploratory testing, regression, end-to-end testing, release validation, and creating clear, actionable bug reports. I also use AI-powered tools to improve test coverage, generate edge cases, validate AI features and prompts, and accelerate testing without compromising quality. **My expertise includes:** • Web, Mobile & Desktop Testing • API Testing (Postman, Swagger) • Manual, Regression & Exploratory Testing • End-to-End Testing • AI & LLM Feature Testing • Cross-Browser & Cross-Device Testing • Test Case Creation & Bug Reporting • Jira, TestRail, BrowserStack, Charles Proxy, Firebase I'm proactive, detail-oriented, and focused on helping teams release stable, user-friendly products. Whether you need a one-time QA audit or ongoing testing support, I'm ready to help.

I find the bugs that reach production, payment flows that fail on one device, permissions that leak across roles, builds that pass smoke tests and break for real users. Before going full-time freelance, I was a Software QA Analyst at Safemoon, testing crypto and DeFi under real financial risk. Since then: AI voice agents, AI-powered accounting (Hedgi), blockchain and DeFi platforms, AI personal assistants, booking and healthcare systems, including a $36,000 end-to-end manual and automation engagement on a web application and API. 𝐖𝐇𝐀𝐓 𝐈 𝐓𝐄𝐒𝐓 Web applications and SaaS platforms. iOS and Android mobile apps. AI applications, voice agents, and chatbot workflows. Blockchain, DeFi, and crypto platforms. Fintech, subscription, booking, marketplace, and healthcare systems. APIs, integrations, dashboards, payments, and role-based workflows. 𝐇𝐎𝐖 𝐈 𝐖𝐎𝐑𝐊 Functional, regression, and end-to-end validation on 40+ real devices across iOS and Android, plus BrowserStack for browser coverage. Automation support with Cypress, Selenium, Playwright, and Momentic; API testing in Postman and Bruno. Reports in Jira, Linear, TestRail, ClickUp, or Notion — prioritized by severity, with reproduction steps, expected vs. actual results, environment details, and Loom recordings. Every engagement ends with a release-readiness summary: what's fixed, what's still risky, and whether I'd ship it. I don't just click through screens. I test business rules, user journeys, integrations, edge cases, error handling, permissions, and data accuracy- the places production failures actually originate. For larger or multi-platform projects, I lead a nine-person QA team through my agency, SmartCodeQA. Send me your build or testing scope, and I'll tell you honestly what needs testing before your next release.
