@sergeshcherbinka
I build reliable QA automation for web, mobile, API, and backend systems.
ZimbabweWhat I'm looking for
I've improved quality across Dragon Money's gaming platform, FeeSaver's TRON-based crypto workflows, and RemedyLogic's healthcare SaaS. My work spans end-to-end web testing, REST and GraphQL API validation, blockchain transactions, payment integrations, and AI-driven features.
At Dragon Money, I increased automated regression coverage from about 30% to 70% and reduced regression cycles from 2–3 days to 6–8 hours by strengthening Python, Selenium, and Pytest automation. At RemedyLogic, I used JMeter to uncover API bottlenecks and contributed to an approximately 30% response-time reduction after fixes.
I've also tested iOS and Android products for Gloria Jeans, smart-device ecosystems at SberDevices, and mobile applications at e-Legion. I bring 15+ years of hands-on experience across fintech, blockchain, healthcare, e-commerce, gaming, and streaming systems.
