What I'm looking for

I'm seeking a .NET Developer role where I can apply my C#/.NET expertise to build reliable APIs, maintainable services, and scalable application components.

At Nexon Dev Vina, I develop and maintain software features in C# across existing codebases, and build REST and socket endpoints. I also work with SQL Server and EF Core for relational data, alongside MongoDB for document logging.

For a Nexon Dev Vina project, I designed a network communication layer using Google FlatBuffers to optimize serialization between clients and backend servers. I developed an automated bot framework to simulate 1 million concurrent connections and resolved server-side bottlenecks and bandwidth crashes ahead of public release.

Previously, I developed backend features and APIs for game projects at Playad company and Gosu group. At HVNET Group, I worked on REST APIs, Blazor applications, an Angular management portal, and a Flutter mobile app for Rodbooks.
