Designed and built a two-sided e-commerce platform (menswear trial store, womenswear planned) using Angular 17, ASP.NET Core Web API (.NET 8), and SQL Server. Architected a cost-efficient multi-store deployment on a single VPS with isolated databases and APIs, Nginx domain-based routing, Docker/Docker Compose containerization, and Cloudflare for CDN and SSL. Implemented product image storage via Cloudflare R2 / Azure Blob Storage and a seeded product catalog across six categories. Delivered the full lifecycle: client pitch materials, working demo, a 21-table ER data model, and production-ready technical handoff documentation.
