Project details
"Need a Blazor WebAssembly app that feels modern for users but still stays practical for your team to build and maintain?
I create production-ready WASM solutions for companies that want a rich single-page experience in C# without relying on JavaScript-heavy stacks. As a blazor developer with solid background as a .net developer, I build applications with a structured frontend, secure APIs, and a backend foundation that fits long-term product growth. This project can include a Blazor WebAssembly UI, JWT-based authentication, protected routes, role-based access, and a clean architecture built around separated layers.
Your app can be connected to the UI library your team prefers, including MudBlazor, Telerik, Syncfusion, Blazorise, or DevExpress. On the server side, I can set up the API layer with .net core, while my experience as a .net backend developer helps keep integration, security, and maintainability aligned from the start. This is a strong fit for products that need .net full stack delivery with Docker deployment and GitHub Actions CI/CD.
Send me a direct message, and let’s discuss the scope and phases of your Blazor WebAssembly project."

.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.
