I’m a Full Stack .NET developer with over 5 years of experience working mainly with C#, .NET, and SQL, building and improving enterprise web applications. On the frontend, I’ve worked a lot with AngularJS, have some experience with Angular, and lately I’ve been getting into Next.js, always using TypeScript.

In my previous role, I worked on systems where performance and reliability really mattered. I spent time optimizing queries, reducing unnecessary data loads, and building real-time features with SignalR. I also implemented an invoice processing solution using OCR and AI to extract structured data, which helped reduce manual work and user errors.

What I care about most is understanding the problem behind the requirement. I try to keep things simple and build solutions that actually make sense in practice, not just on paper.

Right now, I’m looking for a backend or full stack role where I can keep learning and contribute to building solid, maintainable systems.
