Freelancer Overview

I have hands-on experience in AI training data workflows, including prompt evaluation, structured data labeling, and annotation pipelines for both LLM and computer vision projects. My background as a full-stack engineer has given me a deep understanding of data quality, consistency, and the importance of robust backend systems for managing large-scale annotation platforms. I am skilled in tools such as PostgreSQL, Redis, and FastAPI, and have contributed to AI annotation platforms where I improved label coverage and reduced latency through optimized data flows and caching strategies. My experience spans leading engineering teams, building analytics dashboards, and implementing end-to-end solutions that support high-quality, scalable AI data operations.
