What I'm looking for

I’m looking for a QA role focused on backend APIs and microservices in a fintech-like environment, where I can own validation (PostgreSQL), perform log-driven root-cause investigation, collaborate with developers, and continuously improve detection and reproduction speed.

I’m a QA Engineer with 4+ years of experience in fintech and backend-heavy systems. I specialize in testing microservices architecture, REST APIs, and data validation at the PostgreSQL level, with a strong focus on contract validation, error handling verification, and comprehensive test design.

I bring hands-on log analysis and root-cause investigation using DataDog and Kibana, working with Kubernetes (k9s) to trace pod conditions and speed up debugging. I’ve supported event-driven architecture testing with Google Pub/Sub, improved backend bug detection rates, and reduced bug reproduction time through in-depth system analysis—while collaborating closely with developers and analysts to localize and resolve issues.
