What I'm looking for

I’m looking to continue leading QA automation and API test strategies in mission-critical products—expanding coverage with modern frameworks and Generative AI, partnering with developers, and improving CI-quality to reduce risk before release.

I’m a Senior QA Automation Engineer with 9+ years of experience in software quality, test automation, and validation of mission-critical systems across financial, telecom, and industrial sectors. I specialize in end-to-end and API automation for distributed systems, pairing modern web architectures with backend integrations to protect business rules, data integrity, and traceability in regulated environments.

I’ve led automation framework POCs, structured test strategies, and leveraged Generative AI (StackSpot AI) to expand scenario coverage and proactively identify risks. From mission-critical banking integrations to mobile and IoT test strategies, I work closely with developers and stakeholders to drive defect analysis, release stabilization, and continuous CI-quality improvements.
