Senior Software QA Engineer

🤩 Hi, I am a Senior QA Engineer looking to partner with development teams to provide them with 100% release confidence! Please feel free to check out my profile to discover how I’ve helped businesses deliver stable, high-quality software to their users. 🔬 I specialize in building & optimizing testing strategies by deeply understanding the product context and its business-critical flows. Through hands-on product experimentation, I investigate potential risks and error zones—from user interactions in the UI down to deeper issues within the information flow and system architecture. Coming from a backend-oriented development background, I look at the bigger picture to fix root causes rather than just symptoms, whether that involves validating relational databases, APIs, interconnected services, different types of architectures, or implementing robust test automation frameworks. 🚀 Whether it's securing the data of emerging SaaS platforms or validating complex workflows for recognized industry leaders, I've got you covered! Please feel free to reach out today so we can see if we are a good fit for each other.
