I build secure .NET backend APIs, automated code evaluation systems, and database-integrated web applications.
UkraineWhat I'm looking for
I've developed RESTful APIs and backend features for an automated LMS through EPAM Systems' Autocode / .NET Lab, using C#, .NET 8, ASP.NET Core, Entity Framework Core, PostgreSQL, Roslyn scripting, and the OpenAI API.
I built AutoCodeChecker-Lms to compile, isolate, and evaluate student C# code in memory. I implemented a security sandbox for unsafe system APIs, integrated automated OpenAI reviews, wrote unit tests with xUnit and Moq, and deployed services to AWS Lambda with Docker.
I've also built an Online Game Store API with dual-database synchronization, JWT authorization, payment retry policies, and QuestPDF reporting. I bring a Software Engineering foundation from Igor Sikorsky KPI and enjoy solving practical backend and integration challenges.
