What I'm looking for

I seek remote roles focusing on data annotation, QA, and preprocessing within collaborative teams that value accuracy, clear guidelines, and opportunities to support ML model improvement.

I am a detail-oriented AI Data Specialist with hands-on experience in data collection, annotation, labeling, and quality assurance across text, image, audio, and video. I deliver accurate, high-quality results for machine learning pipelines while adhering to project guidelines and schedules.

As a freelance contributor since 2023, I have conducted annotation and pairwise comparison tasks, performed evaluations to improve AI-generated content, and preprocessed large datasets for model training. I focus on data integrity by identifying inconsistencies and correcting errors to maintain high data quality.

In a parallel role as a Database Administrator at a cloud computing company since 2022, I manage, maintain, and optimize database systems, perform extraction, transformation, and validation, and support business intelligence workflows. I have strengthened expertise in Linux, SQL, and data-driven processes.

I hold a B.Sc. in Computer Science and certifications in SQL & Database Management, Python for Data Analysis, and Machine Learning Foundations. I am proficient in English (C1/C2) and thrive in remote, collaborative environments where attention to detail and timely delivery are valued.
