At Equals 5, I developed an AI-assisted Visual Regression Testing Agent to compare target environments against reference baselines. I also validated complex workflows across UI, API, and backend layers, including checks in CI/CD and release readiness.

At Upstars, I tested an iGaming web platform, mobile applications, and PWA functionality. I supported production deployments and validated incidents using Sentry, Grafana, and Argo.

At Svitla Systems / Cordial, I tested campaign workflows, customer segmentation, and cross-channel communication for a marketing automation platform. I introduced QA metrics and contributed to reducing Bug Leakage; across my QA work, I have also supported exploratory testing, risk-based planning, and AI-assisted QA workflows.
