Freelancer Overview

I am a detail-oriented software developer with a solid background in building and optimizing web applications, which has given me a strong foundation in handling data with accuracy and efficiency. My experience developing both front-end and back-end systems has equipped me with the skills to structure, validate, and process large datasets—essential for high-quality data labeling and annotation. I am proficient in technologies such as JavaScript, React, Node.js, REST APIs, and various databases (MySQL, PostgreSQL, MongoDB), and have worked on projects requiring secure authentication, data validation, and performance optimization for real-world users. I am adept at collaborating with cross-functional teams to ensure data integrity and usability, and I am eager to apply my technical and analytical skills to contribute to AI training data projects in domains such as computer vision, NLP, or any industry seeking reliable, well-structured data.
