At Kaspi.kz, I implemented an AI assistant for test case generation and review, log analysis, and API test preparation, reducing test preparation time by 45%.

I developed API regression tests for banking microservices with Pytest and Requests, and automated end-to-end UI scenarios with Python and Playwright. This work increased coverage of critical integrations by 40% and reduced manual regression effort by 50%.

I integrated automated tests into GitLab CI and Docker with Allure reporting, and established test data preparation and validation in PostgreSQL. I also conducted performance testing with JMeter and analyzed failures using OpenSearch, Grafana, and Sentry.

At Credo Bank / კრედო ბანკი, I developed a regression suite covering more than 90% of a banking product's functionality. Earlier, at Sravni, I tested web and mobile OSAGO insurance workflows, including REST APIs and cross-browser scenarios.
