What I'm looking for

I seek a collaborative company where I can ensure product quality across complex business logic, mentor juniors, and help build robust QA processes.

I am a Manual QA Engineer with five years of experience testing web and mobile applications, including three years focused in the gambling (iGaming) industry. I specialize in functional, regression, API, and end-to-end testing of complex business logic such as payouts, bonus systems, and payment integrations.

I have built QA processes from scratch by creating test documentation, establishing cross-team communication, and mentoring newcomers. I have hands-on experience validating database records (MongoDB, PostgreSQL), testing APIs (Postman, Insomnia), and verifying streaming data in Kafka.

In past roles I worked on payment flows, tournaments, jackpots, and financial transaction accuracy, and I served as a Test Lead on an internal project where I established QA workflows and onboarded interns. I am ISTQB Certified (Foundation Level) and comfortable using Jira, Confluence, TestRail, GitLab CI/CD and Jenkins.

I am passionate about product quality, clear workflows, and effective collaboration, and I bring a practical, detail-oriented approach to ensuring reliability and correctness in complex systems.
