Professional Portfolio

I developed this professional portfolio platform as a comprehensive full-stack project that showcases my most advanced technical skills. Built with Next.js 14 and App Router, the project features a modern architecture with TypeScript, implementing complete internationalization for global reach, persistent dark/light theme system, and mobile-first responsive design. I dynamically integrated my projects via GitHub API, developed a functional contact system with server-side email processing using Nodemailer, and fully optimized for SEO with structured metadata. The platform achieves 95+ Lighthouse scores, demonstrating excellence in performance, accessibility, and modern web development best practices. This project represents not only my professional showcase but also a practical demonstration of the technologies and methodologies I master in developing modern web applications.

YOLO Dataset Tools for Fashion Detection - Computer Vision Pipeline

I developed a comprehensive suite of computer vision tools for fashion item detection during my research phase at Styles.AI, creating an end-to-end pipeline for YOLO dataset preparation and model training. Built with Python, OpenCV, and Ultralytics YOLO, the project implements six specialized modules covering the complete machine learning workflow from data collection to model deployment. I engineered a semi-automatic labeling system with interactive annotation workflow, implemented intelligent data cleaning algorithms using SHA-256 hash comparison for duplicate removal, and created automated format conversion tools for batch WebP to JPG processing. The solution features sophisticated dataset management with class-balanced splitting (80/20 train/validation), data synchronization mechanisms to ensure image-label consistency, and an optimized YOLO training pipeline with advanced augmentation strategies including mosaic, mixup, and randaugment techniques. The system handles 86 fashion categories across tops, bottoms, footwear, and accessories, demonstrating expertise in computer vision preprocessing, object detection workflows, and production-ready machine learning pipeline development. This project showcases proficiency in computer vision engineering, automated annotation systems, and scalable dataset management essential for real-world AI applications in fashion technology.
