Freelancer Overview

I am an experienced software and AI data engineer with a strong background in building scalable data platforms and automation solutions for logistics, e-commerce, and financial domains. My expertise includes designing and implementing robust data pipelines, developing AI-driven data validation and annotation systems, and integrating human-in-the-loop review flows to ensure high-quality training data for machine learning models. I have hands-on experience with Python, FastAPI, Pandas, and modern AI/LLM tools like OpenAI and Hugging Face, as well as working with vector databases and RAG pipelines for advanced document analysis and metadata extraction. My work has involved automating data collection, cleaning, labeling, and enrichment processes, significantly reducing manual effort and improving data accuracy across large-scale projects. I am passionate about creating reliable, maintainable data workflows that empower teams to build effective AI solutions.
