What I'm looking for

I'm looking for .NET / Backend Engineer or Senior SDET roles, ideally remote across the EU, UK, or US, or hybrid.

At RF-SMART, I develop C#/.NET backend services and REST APIs that connect its mobile warehouse platform with Oracle Fusion Cloud SCM. They sync warehouse transactions—including receiving, putaway, picking, and shipping—with Oracle Cloud in real time.

At Billsby, I owned the C# test automation framework for UI and API testing and integrated automated tests into CI/CD pipelines. At DataArt, I developed Oracle Cloud SCM integration features and bug fixes, and defined a Test Pyramid strategy that helped stabilize the automated test suite and cut false failures.

Earlier, I worked in QA and test automation at Luxoft, N-iX, Diceus, and QA Mentor. My work included UI and REST API automation with Selenium, SpecFlow, and RestSharp, as well as functional and regression testing for web and banking applications.
