Freelancer Overview

With over six years of experience as a software engineer, I have developed and maintained scalable backend and frontend systems that rely heavily on high-quality data pipelines and structured data management. My work in fintech, media streaming, and SaaS platforms has involved designing APIs, integrating third-party data sources, and ensuring reliable data flow between services, which are critical foundations for data labeling and AI training data projects. I am proficient in Python (FastAPI), Node.js, PostgreSQL, and MongoDB, and have implemented authentication, data validation, and schema design to support robust data annotation workflows. I am passionate about clean architecture and enjoy collaborating across teams to deliver reliable, production-grade solutions that enable accurate and efficient data processing for AI-driven applications.

Labeling Experience

AI Dataset Annotation & Categorization Project

CVATImageBounding BoxClassification

Worked on annotating and categorizing datasets for AI model training. Labeled over 1,500 image samples using bounding boxes and attribute tagging. Performed text classification and sentiment tagging for structured NLP datasets. Followed strict quality assurance guidelines, performed double reviews, and maintained high annotation accuracy (above 95%). Collaborated with developers to refine labeling taxonomy and improve dataset consistency.
