Project work
From requirements to a resilient solution.
A concise look at the context, implementation and technical decisions behind the project.
Starting point
DuoByte built an integrated automotive platform for ADG Sales that connects its public brand experience with the operational workflows of an international vehicle distributor. Multilingual model and corporate pages present brands including Dongfeng, Voyah and Venucia, guide prospective buyers to vehicle offers and support dealer contact and partner acquisition. Behind the secure login, the application connects retail partners and internal ADG teams through two role-based workspaces.
Implementation
In the Dealer Box, authorized dealers filter in-stock, inbound and factory-order vehicles, build a cart and complete a validated purchasing flow with purchase and contract documents generated automatically. The Distribution Box brings together dealer applications and distribution rights, purchasing and price lists, audits, logistics, vehicle intake and aftersales workflows such as warranty and support cases.
Quality & operations
A Fastify backend integrates MongoDB with multiple existing MySQL company databases and protects vehicle purchases, permissions, audit trails and status transitions through transactional workflows. React, TypeScript, Docker, Caddy, SFTP document storage and automated CI/CD pipelines provide a maintainable and extensible foundation for day-to-day operations.
