What I'm looking for

I seek remote roles where I can improve AI model accuracy and product quality through rigorous testing, annotation, and cross-functional collaboration.

I am a detail-oriented QA Tester and AI Model Trainer with extensive experience in manual and automated testing, model evaluation, dataset annotation, and content moderation across web and mobile platforms.

I have improved testing efficiency using Selenium and TestNG, contributed to LLM and AI model quality through structured feedback and dataset curation, and enforced content policies while maintaining community standards.

I collaborate effectively with distributed teams, deliver data-driven insights to improve product performance, and apply strong analytical and communication skills to ensure compliance and model accuracy.
