What I'm looking for

I seek a full-time role as an AI Trainer or Data Annotator where I can apply precise labeling, coding skills, and collaborative problem-solving to improve AI systems and grow professionally.

I am a motivated, detail-oriented IT and AI enthusiast with hands-on experience in web and Android development, data annotation, and AI model training. I have labeled and classified text and image datasets, reviewed AI outputs for accuracy, and used structured feedback to improve LLM responses.

As a developer I have designed responsive websites and Kotlin-based Android apps, implemented user-friendly interfaces and backend logic, and collaborated via GitHub for version control. I am eager to contribute technical and analytical skills to global AI projects while continuing to grow as a data and software professional.
