What I'm looking for

I am looking for a role in an innovative environment where I can contribute to ethical AI development and enhance user experiences.

I am an AI-focused professional with extensive experience in Large Language Models (LLMs), particularly within Google's Gemini (Bard) ecosystem. My expertise lies in high-precision data annotation, prompt engineering, and algorithmic evaluation, which has allowed me to refine AI-generated outputs and align model behavior with ethical guidelines. I have a strong background in enforcing annotation and QA protocols, ensuring that model outputs consistently meet stringent accuracy and relevance benchmarks.

Throughout my career, I have contributed to optimizing natural language responses within virtual assistant frameworks like Google Assistant, leading to measurable improvements in user engagement and system reliability. My unique blend of analytical, creative, and operational skills stems from my background in QA, content evaluation, and international brand management. I am eager to leverage my skills in an innovative IT or AI-driven environment, focusing on building ethical and intelligent digital systems.
