@joannauser
Test automation engineer specializing in payments, Python, and end-to-end quality assurance.
PolandWhat I'm looking for
I am a test automation and system engineer with strong domain knowledge in payments, embedded systems, and data processing. I have developed automated API and end-to-end tests for backend and frontend components, validated Kafka message flows, and implemented test parallelization to significantly reduce suite runtime.
My background combines MEng-level computer science and electrical/embedded systems training with hands-on roles in QA automation, software/system engineering, and maintenance at international companies. I have experience with Python, Java, Selenium, Playwright, Docker, CI tools, databases (MSSQL, MongoDB, Neo4j), and automotive/ISO standards.
I bring a pragmatic, quality-focused approach: reporting critical bugs, improving system stability, enhancing user experience through usability testing, and delivering clear documentation and system configurations. I work well in cross-functional teams, follow Scrum and V-model methodologies, and prioritize reliable, measurable improvements.
