What I'm looking for

I’m looking for a QA role where I can deliver strong manual testing and grow Python-based automation, improve coverage, and support teams with CI/CD, microservices, and AWS—while building stable, reliable release processes.

I’m a QA Engineer with ~5 years of experience testing web, mobile, and desktop applications. I specialize in functional, regression, system, integration, API, and UI testing, and I build practical automation using Python.

In my recent role at Adalisk, I increased test case coverage by ~40%, reduced production bugs by ~25%, and automated part of the tests with Python. I also implemented testing processes from scratch to improve release stability and support teams working with AWS and 3D visualization systems.

I’ve worked across microservices-based products, including preparing test environments and participating in CI/CD processes with tools like Jenkins. I enjoy collaborating with stakeholders and continuously improving test documentation, coverage, and feedback loops using Jira, Confluence, and modern debugging tools.
