E-commerce platform with a gate configurator

Task: Built a full e-commerce platform with a product catalog, accounts, and checkout - plus an extra tool where customers can design a gate step by step and see the price update automatically, based on pricing rules from the company's Pragma system.

• Developed an interactive visual gate configurator with dynamic calculations based on SQL formulas retrieved from the Pragma system.

• Implemented a fully multilingual system to support multiple languages across the platform.

• Built secure authentication with role-based access control for different user roles.

• Designed and developed role-specific user dashboards and management panels.

• Integrated SOAP APIs with the Pragma system to synchronize products, pricing, credits, debts, and other business data.

• Implemented automated cron jobs to periodically fetch data from Pragma via SOAP and store it in Payload CMS (MongoDB).

• Integrated Stripe payment processing to enable secure online transactions.

• Implemented PDF generation with Puppeteer for orders.

• Managed application state using Redux Toolkit for scalable and maintainable data flow.

• Designed a role system including Manager, Dealer, and Subdealer accounts.

• Implemented dealer discount logic where managers can assign custom discount rates to dealers.

• Ensured dealers see product pricing automatically recalculated with their assigned discounts upon login.

• Built functionality allowing dealers to create and manage subdealer accounts.

• Implemented margin settings so dealers can define custom price markups for their subdealers.

• Developed dynamic pricing logic ensuring subdealers see updated prices based on dealer-defined margins.

• Maintained secure data access boundaries so each role only sees permitted pricing and accounts.
