Pavlo V.

I’m a .NET developer with 15+ years of experience building and maintaining production systems, including high-load and legacy-heavy environments. My core stack aligns directly with your requirements: C#, ASP.NET Core (Web API), Entity Framework (Code First), and MS SQL, with practical experience designing scalable backend services and optimizing performance-critical paths. In addition to backend development, I also have strong frontend experience with Angular and TypeScript, building complex SPA applications, integrating REST APIs, and maintaining large-scale enterprise frontend codebases. I’m comfortable working across the full stack and coordinating frontend/backend architecture to keep systems maintainable and scalable. I’ve worked on systems handling large request volumes (up to ~1M requests/day), where I focused on diagnosing bottlenecks (indexes, query plans, inefficient procedures) and improving performance without breaking existing behavior. Most of my work involved real-world constraints: legacy code, evolving business logic, and the need to extend systems cleanly instead of rewriting them. On the cloud side, I have hands-on experience with Azure services and understand how to design distributed systems: REST APIs, inter-service communication, and asynchronous processing patterns. I’m comfortable working with messaging (Service Bus–style patterns), storage, and scalable architectures that fit IoT-like workloads. I follow clean architecture principles, participate actively in code reviews, and work with CI/CD pipelines (Azure DevOps). I also use unit testing tools like xUnit and Moq when it makes sense for system stability and regression protection. What makes me a strong fit for your team: • Strong full-stack experience with both backend (.NET/C#) and frontend (Angular/TypeScript) • Experience working on long-term products and stable teams, not just short freelance engagements • Focus on practical, maintainable solutions rather than overengineering • Ability to work independently and contribute to architecture decisions • Hands-on experience dealing with real production issues, not only greenfield development Technologies that I have used in my projects: Languages: C#, SQL, JavaScript, TypeScript Frontend: Angular 18, NgRX, RxJs, SignalR, HTML, SCSS, Material Backend: .NET Core, ASP.NET Web API, AWS Lambda, Amazon S3, ASP.NET MVC, Docker, RabbitMQ, CosmosDB, Azure DBMS: SQL Server, PostgreSQL, SQLite, Access DB, T-SQL, LINQ, Entity Framework, EF code first, ADO.NET Testing: NUnit, XUnit, MS Test, Moq Cloud: Azure Portal, Azure DevOps Operating Systems: Windows Version Control: GitHub, Bitbucket
