What I'm looking for

I'm seeking a role where I can lead or mentor engineers, work on backend/cloud architectures (ASP.NET Core/Azure), tackle legacy migration, and grow technically in an agile team.

I'm a backend software engineer with over four years of professional software experience and a Bachelor's in Software Engineering from University of Singidunum, Belgrade. I architect and develop scalable solutions using ASP.NET Core and SQL Server, and I have hands-on experience with performance tuning and migrating legacy systems to modern architectures.

I have led a cross-functional team of three engineers, providing mentorship, running code reviews, and establishing coding standards and best practices to improve code quality and maintainability. I work with Azure, Azure DevOps, Git, and automated testing frameworks such as xUnit and NUnit to support CI/CD and agile delivery.

I'm motivated to work with new technologies in a positive environment, enjoy collaborating with clients to implement requirements via REST APIs, and bring strong attention to detail, teamwork, and time management to every project.
