Dastgyr

#problem

Dastgyr is a B2B e-commerce platform for wholesale trading that connects SMEs, retailers, and suppliers across emerging markets. It addresses the fragmentation of wholesale procurement by giving buyers and suppliers a single marketplace for catalogs, ordering, and fulfillment. The system is engineered to scale with growing supplier and retailer participation.

#what-i-built

• ▸I designed and built the Nest.js backend that powers the B2B marketplace, including the APIs for catalog, ordering, and supplier-retailer workflows.
• ▸I developed the web application on the MERN stack, implementing the React front end and the Node.js service layer against MongoDB.
• ▸I architected the platform for scale to support a growing base of SMEs, retailers, and suppliers across multiple markets.
• ▸I deployed and operated the system on AWS, owning the cloud infrastructure and the CI/CD pipeline from environment provisioning through release.
• ▸I owned the engineering end to end, from API and data modeling through the front end and cloud delivery.

Production B2B wholesale marketplace live at dastgyr.com — full-stack system supporting SMEs, retailers, and suppliers across emerging markets.

#key-decisions

• 1.Chose Nest.js over plain Express to enforce domain separation across supplier, buyer, and catalog services as the marketplace scaled in complexity.
• 2.Used MongoDB for the product catalog to accommodate flexible, supplier-defined attributes without schema migrations per product category or market.
• 3.Designed the data model for multi-market scale from day one — supporting multiple regions, currencies, and supplier taxonomies without per-market code forks.
• 4.Deployed on AWS with environment-isolated configurations to support separate staging and production supply chains without cross-environment data contamination.
