The project is a video commerce platform designed to help e-commerce businesses increase product sales through interactive video experiences. It offers three core solutions. The first enables live sessions with video streaming, real-time chat, product showcasing, analytics, polls, and discount features. The second focuses on shoppable videos, allowing products to be attached to videos and seamlessly embedded into clients’ websites. The third solution is an advanced timeline-based experience that combines videos, products, images, and polls into an interactive, time-structured format.

• Designed and contributed to the overall software architecture, ensuring scalability, reliability, and maintainability across the platform;

An AI-powered product recommendation and discovery platform designed to enhance e-commerce search and product discovery experiences. The core solutions included intelligent text and image search capabilities within clients’ product catalogs. The platform processed client catalogs through an ingestion pipeline, converting each product into AI-driven models. Products were enriched with automatically generated tags for improved text search, and all product images were stored as vectors in a vector database for similarity search. Clients could then integrate the solution into their websites to enable smart text-based search or visually similar product search, enhancing user experience and product discovery.
