I build and lead scalable web, mobile, and API automation that improves release reliability.
North MacedoniaWhat I'm looking for
At ScyllaDB, I design Playwright-based automation, automate GraphQL and REST API suites with Axios, and build GitHub Actions pipelines for multi-environment CI/CD.
I lead go-live deployments, investigate production issues through Grafana and DataDog, and mentor junior QA engineers on automation practices. As part of the AI Champions team, I help colleagues adopt GitHub Copilot to improve developer efficiency.
Previously at HTEC Group and Endava, I led QA teams, built scalable UI and API frameworks with Cucumber, WebdriverIO, Protractor, RestAssured, and RestTemplate, and supported AWS-hosted microservices. I also introduced automation standards, coordinated end-to-end testing, and used Splunk for production monitoring and root-cause analysis.
My experience also includes HR platforms, fintech, insurance, and mobile gaming, where I tested iOS and Android apps, managed app store deployments, and validated in-app purchases. I focus on practical automation that catches defects earlier and helps teams release with confidence.
