Ilya Bershadskyi

I led the development of a real-time inventory management platform synchronizing stock across IKEA's digital and physical channels. Built with Go, Kubernetes, and the Google Cloud Platform (GCP), the platform processes millions of daily inventory updates, ensuring accurate stock levels and optimizing allocation across warehouses and stores.

As a software developer, I led critical improvements to the search functionality in the company's flagship mobile app, enhancing speed and relevance for millions of daily users. I architected and implemented RESTful APIs that reduced search latency by 15% while increasing result accuracy through advanced filtering algorithms. Additionally, I developed a sophisticated in-app revenue tracking system for pre-install partnerships, which enabled precise attribution analytics and contributed to a 28% increase in partner-driven conversions. Working in an Agile environment with a diverse international team, I leveraged Java/Kotlin back-end technologies and collaborated closely with front-end developers to create seamless user experiences. This project required both deep technical expertise and strong business acumen to align technical solutions with revenue goals.
