Freelancer Overview

I am a detail-oriented front-end developer with extensive experience in building and optimizing web and mobile applications, where data integrity and accurate data handling are essential. My work integrating complex Python-based REST APIs and designing modular, reusable UI components has given me a strong foundation in managing structured data, validating user input, and transforming raw backend payloads into clean, UI-ready models. I have a deep understanding of error handling, data validation, and maintaining data quality throughout application workflows, which aligns closely with the needs of data labeling and annotation for AI training data. My projects have required me to collaborate with cross-functional teams to deliver production-ready dashboards and reporting platforms, emphasizing structured data presentation and reliable data synchronization. I am skilled in implementing robust validation logic, centralized error handling, and pre-release testing to ensure high data accuracy and consistency—key factors in creating quality AI datasets. Highly adaptable and self-driven, I am eager to apply my technical expertise and passion for data quality to support data labeling, annotation, and AI training initiatives in any domain.

Labeling Experience

AI Data Annotation & Quality Assurance Specialist (Multi-Domain)

ImageBounding Box
I worked on image data annotation projects focused on training computer vision models. My responsibilities included labeling objects using bounding boxes, performing image classification, and applying semantic segmentation for detailed object recognition. I handled diverse datasets such as product images, real-world scenes, and objects from different categories. I ensured high-quality annotations by strictly following labeling guidelines and maintaining consistency across datasets. I also performed quality checks to minimize errors and improve dataset accuracy, consistently achieving over 95% annotation accuracy. My work contributed to AI systems used in product detection, object recognition, and automated visual analysis.
