What I'm looking for

I'm looking to build and improve quality automation and application security across web, mobile, or backend products, collaborating closely with developers and product stakeholders on reliable releases, API integrations, CI/CD, and secure SDLC practices.

I've delivered Python-based UI and API automation at RedCore, Fylpi, and Gremi Personal Poland, testing web, mobile, backend, CRM/ERP, and payment products. I validate REST and gRPC integrations, build Playwright and Pytest coverage, and support CI/CD workflows across regression, end-to-end, smoke, and exploratory testing.

My security background includes SOC monitoring, vulnerability assessment, incident response, IAM, network security, and security testing. I've tested payment flows with Stripe, PayPal, Mono, and Way4Pay, and I bring practical experience turning requirements and acceptance criteria into reliable test documentation and release validation.
