Experience

Logistics Printing System

I designed and developed a large-scale printing solution for logistics. The project included load-balancing of thousands of printers, printing shipping labels multiple times per second, and automated retries and smart fallback in case of failure.

eCommerce Customer Support Chatbot

I developed a customer support chatbot for the largest eCommerce platform in Hepsiburada, Turkey. The chatbot was used to greet users, collect information, and solve specific issues. If the problem couldn't be resolved automatically, it redirected the users to human agents, saving time and resources.

Peer-to-peer Banking Application
