Telegram My passion for QA started with years of using beta versions of apps and
operating systems — exploring new features from a user’s point of view.
This background helped me develop strong attention to detail, technical
thinking, and a proactive approach to identifying issues early.
Education Previously worked in banking and technical support, handling a wide
2018 - 2022 range of client requests and delivering results in high-pressure
National Aviation University situations. This experience strengthened my multitasking abilities,
Bachelor in Civil Security stress resilience, and communication skills — all essential qualities I
bring to QA work.
