What I'm looking for

I’m looking for a QA role where I can own quality end-to-end, strengthen API/backend validation and release verification, and collaborate in fast-moving teams—while applying QA operations/process optimization and (where relevant) AI workflow automation.

I’m a Manual QA Engineer with 5+ years of experience in web, mobile, API, and backend-oriented testing across fintech, telecom/security, IoT, and digital product domains. I’ve worked in international English-speaking teams on enterprise-level products with microservices architecture, traffic filtering systems, and AWS IoT ecosystems.

My strength is end-to-end quality ownership: from requirements analysis and test design to regression, release verification, production support, and bug investigation. I focus on API testing and backend validation, Kafka message tracing, Linux log analysis, and complex business logic testing to ensure issues are caught early and validated thoroughly.

Beyond QA execution, I’ve built credibility through QA operations and leadership—coordinating workflows, documentation, contributor onboarding, and operational coordination. Currently, I lead private Telegram-based digital operations involving AI content production and automation workflows, including LoRA training and prompt/visual content production—while continuously improving reporting and process efficiency.
