What I'm looking for

I’ll be most effective in teams building web or mobile products where mistakes are costly and that want to systematically reduce critical defects in releases throughout the product lifecycle.

At Antara, I reviewed application-submission forms with analysts and helped increase the share processed correctly on the first attempt by 25%. I also verified subsidy-eligibility calculations across applicant categories, reducing manual accrual corrections by 35%.

Previously, at Agent Umnyy Polis, I tested the policy-issuance funnel and payment changes, contributing to fewer critical release defects and higher conversion. I work across functional, regression, integration, and API testing, using tools such as Postman, PostgreSQL, Kafka, and TestIT.
