What I'm looking for

I want to keep building expertise in backend/API and AI/LLM quality—owning integration testing, automation, localization validation, and production verification—while partnering closely with engineering in an agile team to ship reliable distributed systems.

I’m a QA Engineer with 4+ years of experience testing backend, microservice, mobile, and AI-powered products. I focus on API and integration testing across distributed systems, combining strong defect analysis with risk-based and shift-left approaches to prevent issues early.

In recent roles, I’ve tested AI-driven content generation workflows end-to-end, including multi-step agentic workflows and MCP-backed integrations, and supported localization QA across 41 languages. I also worked with Kafka-based integrations, production monitoring, and release verification, using automation (Java, RestAssured, Selenide, JUnit 5, Allure) and evaluation tooling like DeepEval and Grafana to deliver clear quality reports.
