Engineering case study / Full-stack
PazarPilot.
One workspace. Multiple marketplaces.
01 / The problem
What needed solving.
Selling across Trendyol and Hepsiburada means coordinating listings, stock, orders and shipping across separate systems. PazarPilot brings those operations into a shared workspace.

03 / Engineering decisions
Make a marketplace an adapter
Each channel sits behind a shared adapter interface. I implemented REST clients with OAuth token refresh and retry logic for listing and order synchronisation across two marketplace platforms; adding a channel does not require a rewrite of the product.
Connect the operational details
The panel combines listing management, orders, stock locations, inventory movements and stock overview. A shipping carrier API supports shipment creation, label generation and status tracking.
Surface exceptions
A rule engine raises alerts for critical stock, cross-channel price mismatches and sync failures. The intent is to help the operator find issues that need attention.
04 / Where it stands
Built during the six-month Nest2Move internship, with Docker and Docker Compose environments. Marketplace API clients and shipping workflows were implemented; production seller rollout has not been verified for this case study.
