What I'm looking for

I'm looking to continue building reliable, maintainable software with modern .NET technologies, integrations, and cloud concepts while collaborating closely with analysts, QA engineers, and developers in Agile teams.

I've built and maintained HRM and payroll systems at Visma Labs for Swedish public sector organisations, developing enterprise applications with C#, .NET, SQL Server, and Entity Framework.

I design WCF and SOAP integrations, consume REST APIs, and create test applications that simulate partner systems for independent integration testing. I also improve SQL performance, resolve production issues, and maintain legacy applications built with Classic ASP, C++, and VBScript.

Earlier, I developed payment terminal and POS software at Verifone Baltic and Point Transaction Systems. I'm continuing to build personal projects with ASP.NET Core, React, and .NET MAUI while learning modern .NET and cloud concepts.
