What I'm looking for

I seek a collaborative Agile team role focusing on manual and API testing, strong documentation, career growth, and opportunities to improve QA processes.

I am a QA Engineer with over three years of hands-on experience testing complex web and microservices platforms, focusing on functional, regression, integration and API testing. I have driven quality improvements at scale—creating structured Confluence documentation, converting checklists to parameterized test cases, and identifying critical issues early in grooming sessions.

I work effectively in Agile/Scrum teams, collaborate with developers, analysts and designers, and use tools such as Postman, Swagger, Jira, Zephyr, PostgreSQL, Kafka, Kibana and Grafana to validate back-end and front-end behavior, analyze logs, and monitor application metrics. I am willing to relocate and travel and bring a pragmatic, documentation-driven approach to ensure reliable, user-friendly releases.
