A distributed web crawler built to monitor over 40,000 products and notify the owner when items go out of stock. Optimized for performance, it crawls the entire product catalog in just ~10 minutes while keeping infrastructure costs minimal.
Developed as a customized inventory management solution for a dropshipping business, the system ensures daily synchronization with the manufacturer’s website to prevent the sale of unavailable products. This not only improved operational efficiency but also enhanced customer experience by guaranteeing that only in-stock items were displayed, ultimately boosting sales and reducing order cancellations.

CareerGPT is an AI-powered conversational career coach built using React, Django, and OpenAI APIs. It helps users explore career options, improve their resumes, and prepare for interviews through natural, interactive conversations. Users can describe their interests or upload resumes, and CareerGPT intelligently suggests relevant roles, rewrites resume sections, or simulates interviews using GPT-4’s language capabilities. The Django back end handles API orchestration and session management, while React delivers a smooth, chat-first user experience.
The platform emphasizes adaptive conversational UX with role-based personas—like a startup CTO or an empathetic career coach—that tailor tone and guidance to each user.
It also offers personalized upskilling recommendations, answering questions like “What’s next after 5 years in QA?” or “How do I break into product management?” in context-aware, helpful ways. With a clean React front end, a robust Django back end, and the power of OpenAI’s language models, CareerGPT showcases full-stack integration of intelligent assistance with a focus on real-world usability.
