UkraineWhat I'm looking for
I've tested enterprise Healthcare products at GlobalLogic and 10 parallel E-Commerce projects at Mobilunity, covering functional, regression, end-to-end, cross-browser, UI, and accessibility testing.
During my AI QA and model evaluation training, I assessed ChatGPT- and Midjourney-generated content, tested LLM guardrails against prompt injection and jailbreaks, completed all eight Lakera Gandalf levels, and studied Web LLM attack vectors through PortSwigger.
I'm an ISTQB-certified QA professional who creates practical test documentation, verifies data with SQL, tests APIs with Postman, and has mentored junior QA engineers.
