You will get Blazor Developer | .Net Core | .NET Backend with gRPC & Blazor UI
Top Rated
Project details
Need a faster backend when REST is too slow for real-time data, internal services, or high-load communication?
I can help you build production-ready gRPC systems with ASP.NET Core services, strongly typed protobuf contracts, binary serialization, HTTP/2 multiplexing, native streaming, authentication, logging, retries with backoff, health checks, and Blazor frontend integration. My .net developer experience covers high-performance service architecture, while my .net backend work includes secure APIs, microservices communication, deadline propagation, cancellation tokens, client-side round-robin load balancing, graceful shutdown, and connection draining.
For frontend needs, my blazor developer skills help connect Blazor WebAssembly apps through gRPC-Web for real-time feeds, uploads, dashboards, or live collaboration features. I also provide .net full stack delivery when you need backend infrastructure plus user-facing Blazor functionality. The implementation follows .net core best practices and can support pricing engines, document pipelines with client streaming, chat-like systems, and large file uploads.
Let’s build a fast, scalable gRPC solution ready for production.

.NET Full Stack Developer (Blazor .NET Core Specialist)
It was a pleasure to work with such a detail-oriented professional. As a highly skilled .NET Full Stack expert, he seamlessly handled everything from .NET Core microservices to sophisticated Blazor Developer interfaces. His expertise as a .NET Developer across the entire Microsoft ecosystem, including legacy systems and MySQL optimization, is truly impressive. Clear communication and exceptional code quality throughout the project. Highly recommended

Senior Developer | .NET | MAUI
Serg worked on my team for over a year as a Senior MAUI/C# Fullstack Developer. He quickly adapted and became productive with minimal guidance. He worked efficiently both independently and with other developers, QA, and managers, and consistently delivered on time. He is skilled in iOS development, Swift, C#, .NET MAUI, the Mescius ComponentOne framework, and REST APIs. His work designing and implementing an in-memory SQLite database architecture was a breakthrough that significantly contributed to the success of the entire project. He followed solid engineering practices such as design-first thinking, TDD, and effective use of AI tools. Serg demonstrated strong work ethic and communication. The project was successfully completed. Thank you for all your contributions! I look forward to working with you again.

✔️Legacy code makes updates slow, risky and expensive
✔️Web, backend, and mobile parts stop working as one system
✔️Performance issues affect users and operations
✔️Technical debt grows faster than the product itself
✔️Teams need secure, maintainable and scalable software
If this sounds familiar, we should talk.
As a .Net full stack Developer and Blazor developer I help companies design, modernize and scale secure business applications with a strong focus on maintainability, performance and long-term product stability.
━━━━━━━━━━━━
Core expertise
━━━━━━━━━━━━
My main focus is Blazor c# and .Net full stack. As a Blazor developer I specialize in enterprise-grade delivery where architecture quality, security, and predictable execution matter as much as speed. I have supported SaaS platform delivery, migration and upgrade projects, and refactoring legacy systems for products that needed modernization without disrupting business operations.
As a full stack developer ( web developer ), I work across frontend, backend, API, database and deployment layers, including HTML ( HTML5 ), JavaScript, jQuery and MySQL when legacy or mixed stacks require them. As a backend developer, I design systems that remain stable under growth, easier to maintain and clearer to extend.
I’m usually brought in when a team needs to improve delivery quality, modernize an aging platform, migrate mobile products, or restore control over a codebase that has become difficult to scale.
━━━━━━━━━━━━
What I deliver as a Blazor developer
━━━━━━━━━━━━
I build and improve applications using blazor webassembly, blazor server, .net blazor, blazor c#, blazor maui, mudblazor, blazor syncfusion, blazor telerik and syncfusion for internal platforms, customer portals, dashboards, and cross-platform business tools.
On the service layer, I design and implement asp.net, ASP.NET Core, ASP.NET Web API, ASP.NET MVC, .NET Framework and .net core solutions with restful api architecture, secure integrations, background processing, caching and scalable business logic. My experience as a .net backend developer includes role-based access, secure authentication, structured logging, auditability and performance optimization.
As a maui developer and c sharp developer, I build modern cross-platform mobile and desktop products with strong engineering discipline. My c# programming approach is focused on clean architecture, maintainable code structure, and long-term ownership. I use mvvm where it improves testability and keeps mobile or desktop solutions easier to evolve.
I also work with azure serverless and azure function patterns when a product benefits from modular cloud execution, event-driven workflows or lightweight service orchestration.
━━━━━━━━━━━━
Best-fit project types
━━━━━━━━━━━━
I’m a strong fit for:
SaaS platform development
migration and upgrade projects
Xamarin to MAUI modernization
enterprise dashboards and internal systems
secure API and backend architecture
Blazor-based web platforms
cross-platform mobile applications with long-term support in mind
━━━━━━━━━━━━
Why clients hire me
━━━━━━━━━━━━
Companies usually bring me in when they need a blazor developer for enterprise UI delivery, platform modernization, performance improvement, cross-platform product strategy, or long-term ownership of a business-critical application.
The same is true when teams need a .net developer to stabilize delivery, modernize legacy systems, improve architecture, strengthen backend services, or support product growth with clear technical direction.
When a product needs .net full stack ownership across backend and frontend, .net full stack execution for web and mobile, .net full stack support for modernization, .net full stack leadership for architecture-heavy delivery, or .net full stack problem-solving during a recovery phase, I can step in quickly and move forward with a structured plan.
🔧Broader collaboration scope
While my core specialization is .NET, I collaborate effectively in mixed delivery environments that include Angular, AngularJS, React, Node.js, (react js ) and react node developer workflows. I can also align with teams using xamarin, wordpress integrations, figma-based handoff, Adobe Photoshop materials, Web Design references, flutterflow prototypes, obs-related workflows, support from a java developer and css responsive adjustments where needed.
🧩Delivery approach
Discovery → technical alignment → architecture definition → iterative implementation → documentation → handover
📍Availability
Based in Ukraine with working overlap for EU and US teams, I continue delivering production-grade software from a secure location.
If you need an experienced engineering partner to build, modernize, or recover a .NET product, I’m ready to help with a clear and realistic approach.
