Bachelor of Engineering (B.Eng.) | Yuriy Fedkovych Chernivtsi National University, Ukraine I’m a .NET developer specializing in building reliable, production‑ready systems for e‑commerce, logistics, and workflow automation. I focus on backend engineering, API integrations, and deterministic data pipelines that keep operations stable and predictable. I build Windows services, DevExpress‑based desktop applications, API integrations, and SQL‑driven ingestion engines using C#, .NET, and SQL Server. My work includes deep integrations with Amazon SP‑API, Amazon Ads‑API, and other retail platform APIs, enabling automated workflows, real‑time data synchronization, and operational visibility across systems. I design systems that reduce manual work, improve operational reliability, and ensure data flows correctly between platforms. My approach is practical, engineering‑driven, and focused on long‑term maintainability — building solutions that behave consistently in real production environments.
