I am a QA Engineer with more than eight years of hands-on experience testing mobile applications, responsive web products, and backend APIs for international clients.
I take ownership of quality throughout the delivery lifecycle, from reviewing requirements and identifying risk to designing tests, validating releases, and following defects through to resolution.
I specialize in end-to-end validation across iOS, Android, web, and backend services. I verify not only the user-facing behavior but also API responses, database state, logs, network traces, and business rules.
I use risk-based testing strategies to build effective test plans, regression suites, smoke checks, and release-readiness reports. My defect reports include clear reproduction steps and technical evidence to help engineering teams resolve root causes.
I have experience working as the sole quality owner on distributed teams and collaborating closely with product owners, analysts, developers, and business stakeholders. I communicate clearly in English and raise risks early during refinement and sprint planning.
I also contribute to quality process improvement through test automation, CI integration, test environment management, reusable test data, testing standards, and colleague onboarding.
Set up testing processes from scratch, including the test approach, test plans, test cases, and a lightweight traceability matrix.
Validate web, mobile, and API layers across end-to-end user flows. Confirm backend state using SQL queries and API responses before release sign-off, maintain Docker/PostgreSQL test environments and seeded test data, and track evidence-based defects through closure.
Owned quality for international web platforms serving clients in Norway, the United Kingdom, and the United Arab Emirates, including a platform operating in 88 markets. Reviewed requirements with product owners and analysts to identify ambiguity and delivery risk early.
Reduced regression time by an estimated 30–40% through risk-based testing and automated CI checks using Playwright, REST Assured, Jenkins, and GitHub Actions. Prepared UAT rounds, investigated recurring defects, verified corrective actions, created testing standards, onboarded colleagues, and reported coverage, risk, and release readiness.
Performed functional, integration, and regression testing of Android and iOS applications and web front ends in short release cycles.
Verified APIs using Postman and Swagger, conducted performance testing with JMeter, and analyzed and reported results. Maintained device and browser coverage and ran cross-platform regression testing before releases.
Tested authentication, payment, and CRM modules on a configured business platform, covering roles, permissions, customer records, and business rules.
Designed positive, negative, and boundary test cases. Supported developers with defect reproduction, investigation, and verification of completed fixes.
Performed API and mobile application testing across product functionality and integrations.
Maintained test cases and regression suites to support repeatable validation during releases.
