Freelancer Overview

I am a detail-oriented software developer with specialized experience in AI data training and multimodal tagging for e-commerce and machinery platforms. I have a deep technical understanding of computer vision workflows, specifically focusing on precise object detection using YOLO-formatted annotations (v8-v11). My background in full-stack development allows me to bridge the gap between data labeling and model integration, ensuring that training datasets are optimized for high-performance outcomes. I am highly proficient in using Roboflow for managing complete annotation pipelines, including data preprocessing and dataset augmentation. My experience includes large-scale projects involving fashion attribute tagging and heavy machinery component identification, where I consistently maintain high accuracy in normalized coordinate placement and class mapping.

This project involved the technical refactoring and data organization of an online fashion catalog to improve user navigation and searchability. Multimodal Attribute Tagging: Implemented a system for tagging fashion items with specific attributes such as style, material, and garment type to enhance filtering capabilities. Catalog Architecture: Transitioned the platform from a modal-based view to dedicated landing pages, ensuring each product had a structured, indexable data entry. Data Integrity: Managed the synchronization between the front-end display and the MySQL database to ensure real-time accuracy of product availability and descriptions. Security Integration: Ensured secure user interactions within the catalog by implementing JWT-based authentication and protected routing.
