Hire the Best Software QA Testers
in Germany

I am a Senior QA Analyst with 8+ years of experience in manual and automation testing across web and mobile platforms. Currently working within a leading organization, I specialize in test case creation, execution, and detailed bug reporting. I collaborate closely with developers and product teams to reproduce issues clearly and verify fixes efficiently. What I bring to your project: 1. Comprehensive Testing: Functional, regression, smoke, and exploratory testing for web and mobile apps. 2. Clear Reporting: Detailed bug reports with precise steps to reproduce. 3. Automation: Writing automated test scripts to cover regression and exploratory tests. 4. User-Centric Mindset: Testing from both technical and real-user perspectives. 5. Reliability: Full project management from start to finish with regular communication. If you need a reliable QA tester to improve your product quality, I am ready to help.

QA Tester with experience in web and real-time systems, focused on finding bugs and delivering clear, actionable reports. Currently working as a QA Automation Tester on a VAR (Video Assistant Referee) project for the Bundesliga, testing complex, high-performance systems. I help teams improve product quality by: • Identifying bugs and edge cases • Writing clear reproduction steps (Expected vs Actual) • Providing screenshots and video evidence • Testing across browsers, devices, and environments Tools: Jira, Confluence, Python (basic automation), OBS, DevTools Devices & Environment: iPhone, Android, Windows PC, MacBook, VPN access for region/location testing I’m detail-oriented, reliable, and easy to work with.

Let’s connect and improve the quality of your project together!

QA Engineer with 6+ years of experience in manual testing across mobile, web, and game applications. Skilled in functional, regression, and exploratory testing with a strong focus on gameplay quality, LiveOps, and user experience. I have supported 68+ releases, identifying critical issues, creating clear bug reports, and ensuring stable, high-quality product delivery. Experienced with Jira, TestRail, and working closely with cross-functional teams.

Shipping software without a solid QA process is risky — bugs slip through, releases get delayed, and clients lose trust. I help startups and small teams build that process from the ground up, then keep it running so nothing breaks in production. I'm a Manual QA Engineer with 5+ years of experience testing web, mobile, API, and hardware-integrated products for clients across the US and Europe. On Upwork, I've worked with 5+ clients who had no QA function at all — setting up their testing standards, workflows, and bug-reporting processes from scratch, including projects in logistics and AI-powered content creation. In my full-time QA role, I also test FDA- and HIPAA-regulated connected medical devices — validating full hardware-software integration across Bluetooth connectivity, mobile apps, backend data sync, and clinician-facing dashboards — so I bring that same level of rigor and attention to detail to every project, regulated industry or not. What I can help with: Manual functional, regression, and exploratory testing (web, mobile, API) Cross-browser and cross-device testing — using real physical devices, not just emulators Hardware-software integration testing (connected/IoT devices) Accessibility and localization testing QA process and test plan/strategy setup for teams starting from zero Structured bug reporting and documentation (Jira) User Acceptance Testing (UAT) coordination AI feature and AI-generated content testing Why clients work with me: ISTQB-certified (Foundation, Advanced Technical Test Analyst, AI Testing, Generative AI Testing) Clear, detailed bug reports — your developers spend less time reproducing issues, more time fixing them Comfortable working directly with non-technical founders as well as engineering teams Fluent in English and Spanish, working German — useful for international teams If your product needs a reliable second pair of eyes before it ships, or you're hiring your first QA person and don't know where to start, let's talk.
