About

Professional summary

I am a Software QA Engineer with nearly four years of experience testing cloud-based web applications and APIs in Agile product teams.

I work across the full software development lifecycle, from refining requirements and acceptance criteria through integration testing and release validation. I collaborate closely with developers, product managers, architects, and stakeholders to identify issues early and support stable releases.

My core strengths include manual, functional, regression, integration, smoke, exploratory, and accessibility testing. I create structured test cases, checklists, test plans, and clear defect reports to ensure thorough coverage.

I validate REST APIs, backend data flows, and databases using Postman, Bruno, Apache Kafka, and SQL. I am also experienced in investigating complex defects through browser network traces, application logs, and database queries.

I build and maintain end-to-end UI automation using Playwright with JavaScript and TypeScript, including AI-assisted workflows to expand regression coverage and speed up validation. I have performed responsive, cross-platform testing across web, iOS, and Android user flows.

I am based in Joensuu, Finland, open to remote opportunities and relocation. I bring a proactive, quality-focused approach to improving product usability, accessibility, and release confidence.
