What I'm looking for

I’m looking for a Senior QA role where I can own end-to-end testing across backend, mobile, and web—especially API and payment flows—using strong observability and AI-assisted QA to improve release confidence.

I’m a QA Engineer with 6+ years of experience testing mobile, backend and web applications at scale, and I’ve worked on products used by millions. I’ve tested checkout and payment flows with international payment methods at AliExpress, an award-winning AI voice assistant for a brokerage app at BCS, and core platform services at Competo.

I’m strong in API testing, payment systems, SQL/PostgreSQL, and production monitoring, and I’m comfortable owning quality end-to-end—from test design to release. I use AI tools daily to speed up test design, log analysis, and documentation, and I rely on observability stacks like Grafana, Kibana/ELK, and Elastic APM to validate real behavior in production.
