Mariana Sargsyan

I am a Quality Assurance engineer with hands-on experience in manual testing for mobile retail applications and clinical-data programming exposure. I built test cases in traditional and BDD formats, validated RESTful APIs with Postman, and used Charles Proxy for network debugging.

At Grid Dynamics I progressed from QA Intern to Quality Assurance Engineer (Manual), executing extensive search capability assessments for 80+ clients and validating 50–80 queries per client while documenting defects and ensuring UI fidelity for client-facing materials.

As a Statistical Programming Intern I standardized clinical trial data using R, converted SDTM to ADaM datasets, and learned CRF annotation—demonstrating adaptability in regulated environments and timely task delivery.

I collaborate effectively in Agile and Waterfall teams, apply test-design techniques (equivalence partitioning, boundary value analysis, decision tables), and communicate findings clearly, supported by certifications in cloud fundamentals and API testing.
