Are you in search of a Senior .NET Developer who can build, scale, and maintain resilient software systems for web, desktop, and cloud-based applications? You’re in the right place. I’m Eugene - a seasoned .NET developer with deep expertise in full-stack architecture, Azure-based services, REST APIs, relational databases, and scalable backend platforms.
Over the years, I’ve taken the lead on mission-critical software projects for top-tier clients, including Microsoft and Shell. I’ve delivered a wide array of business solutions using C#, ASP.NET Core, .NET Stack, Entity Framework, SQL Server, PostgreSQL, WPF, WinForms, and Azure App Services. My portfolio includes scalable web platforms, API-driven microservices, high-performance desktop tools, and cloud-native architectures powered by Docker and CI/CD workflows.
👨💻 Areas Where I Excel:
✅ Full-Stack .NET Development
I craft backend and frontend solutions with ASP.NET Core, .NET 6/8, MVC, Razor Pages, and Web API. I also bring experience with Blazor, Angular, and React, following clean architecture and SOLID design.
✅ Desktop Application Engineering
I build Windows apps using WPF, WinForms, MVVM, and Telerik controls. These include hardware integrations, PDF/image processing, and offline functionality.
✅ API Development & Integration
I create and connect REST APIs with third-party services such as Stripe, Twilio, SendGrid, and CRM systems. I also develop custom APIs for tools like print services and internal dashboards.
✅ Database Architecture & Optimization
I design performant database schemas and manage SQL Server, PostgreSQL, MySQL, and Cosmos DB. I focus on query performance, indexing, and schema evolution.
✅ Cloud & DevOps
I deploy apps using Azure App Services, Functions, and CI/CD with GitHub Actions or Azure DevOps. I containerize services with Docker and orchestrate deployments via Kubernetes.
✅ Microservices & Distributed Architecture
I build .NET Core microservices with RabbitMQ, Kafka, and Ocelot. These systems serve web and mobile platforms with real-time and asynchronous communication.
🔍 Key Project Highlights:
iGaming Platform: Built a real-time casino system using .NET Core, SignalR, Kafka, ScyllaDB, ClickHouse, PostgreSQL, ELK stack, and Power BI. Deployed via Docker on AWS.
Loan Automation: Delivered a full-cycle loan platform with .NET Core, OData, EF Core, Azure Service Bus, Hangfire, CosmosDB, Angular, and Power BI.
App Marketplace: Developed a microservice-based SaaS platform with RabbitMQ, Stripe, Angular 6, Ocelot, Autofac, and SQL Server.
Fleet ERP: Built WPF/Angular tracking ERP with EF6, SQL Server, MEF, GIS, and modules for driver behavior, fuel tracking, and maintenance.
Insurance System: Created a UBI platform on ASP.NET Core, AngularJS, Kendo UI, and MS SQL for fraud detection and claims processing.
Outlook CRM: Developed CRM integration for Outlook using ASP.NET MVC, AngularJS, Kendo UI, Azure Services, and hosted on IIS.
Logistics ERP: Led development of a WPF .NET AngularJS ERP for transport tracking, satellite communication, and business ops.
Medical Monitoring: Built a diagnostics app with ASP.NET MVC, DurandalJS, EF, and MS SQL. Hosted securely via IIS.
Delivered enterprise-grade .NET solutions: real-time, cloud, ERP, CRM, fintech, and diagnostics systems.
🛠️ My Technical Toolbox:
I specialize in C# and the .NET ecosystem, including .NET Core, .NET Framework, Web API, MVC, and WinForms. I rely on EF and LINQ for data access and schema control. My database experience covers MS SQL, PostgreSQL, MySQL, MongoDB, Redis, and Cosmos DB. I manage deployments on AWS and Azure, using Azure DevOps, Docker, and Git. For UIs, I use WPF, Blazor, Angular, and React with TypeScript. I also implement secure CI/CD, API integrations, and scalable infrastructure.
