EXPERIENCE IN E-COMMERCE PROJECTS

I specialise in quality assurance for complex B2B and B2C systems. My experience includes working with platforms such as Magento 2 and Pimcore, where I am responsible for the stability of purchasing processes and integration with ERP systems. I focus on ensuring that digital products not only function correctly, but also deliver real business value whilst maintaining the highest standards of performance.

AUTOMATION AND DATA ANALYSIS

In my day-to-day work, I combine manual testing with process automation using Playwright (JavaScript). I don’t limit myself to the user interface – I’m proficient in API testing (Postman, REST, GraphQL) and data analysis in SQL databases. I use monitoring tools such as Sentry and Kibana to proactively identify errors and optimise system performance under heavy load.
