My team contributed to the logistics platform at Ozon, Russia's second-largest online retailer. We played a crucial role in ensuring the business remained stable during both regular operations and peak periods of seasonal sales. Additionally, we collaborated on developing tools to streamline the entire sales process, from warehouse management to doorstep delivery.In terms of my specific contributions, I primarily focused on backend development tasks:• Participated in the migration of our system from a monolithic database architecture to microservices. Created various microservices to handle client requests, enabling more precise caching and the rewriting of business logic from stored procedures to C#.• One notable achievement was the implementation of a write-off process for our warehouse application, significantly reducing the number of items stored in Ozon's warehouses and minimizing spending on surplus products.
