What I'm looking for

I’m looking to drive end-to-end QA automation and CI/CD quality across microservices, partnering with product and engineering teams to improve reliability, troubleshoot faster with monitoring/logs, and strengthen performance testing in cloud environments.

I’m a QAEngineer and DevOps Support professional with over 5 years of hands-on experience leading QAprocesses, building automation frameworks, and executing end-to-end testing in complex microservices environments.

In my current role (QAengineer at Vennote technologies), I led QApractices for a multi-component chatbot system, designing automated test suites with Cypress, Playwright, and Selenium for frontend and API testing, and driving CI/CD integration through Github actions.

I also focus on reliability and troubleshooting: I perform API and E2E testing with Postman/Newman CLI and Karate DSL, diagnose issues using Swagger plus log analysis tools like Elastic/Kibana, Grafana, and Splunk, and run performance and edge testing with Gatling.

I bring strong infrastructure skills—Docker and Kubernetes, plus IaC with Terraform on AWS and Azure—and I’ve supported production uptime through careful upgrades, monitoring, and technical support practices from prior roles.
