What I'm looking for

I seek a role leveraging full-stack .NET and Azure to build scalable, automated enterprise solutions, with collaborative teams and clear impact.

I am a full-stack .NET developer with over a decade of experience building scalable enterprise systems, ERP applications, and cloud-based solutions. I specialize in C#, ASP.NET Core, WPF (MVVM), Angular, and Azure technologies.

Throughout my career I have delivered measurable results: automating subtitle generation to cut transcription effort by 70%, implementing secure media streaming, and creating ERP modules that became central to daily operations. I focus on performance optimization, workflow automation, and reliable system design.

I have built desktop and web applications, web APIs, integration scripts, and reporting tools using modern practices like dependency injection, repository pattern, and RESTful API design. I also maintain strong database skills across SQL Server, Azure SQL, MySQL, and related performance tuning.

I am collaborative, support cross-functional and international teams, and consistently adopt new technologies to improve delivery and reduce manual effort. I seek opportunities where I can apply my full-stack .NET, cloud, and automation expertise to drive business impact.
