I'm a Full Stack Developer and .NET Developer with 10+ years building web applications that businesses actually run on. I take an idea and ship it — front end, back end, database, deployment — and I've done it for products still serving customers a decade later. ✦ WHAT I DO BEST My core stack is .NET and C#. As a .NET Developer I build secure, scalable back ends with .NET Core and ASP.NET Core, expose them as clean ASP.NET Web APIs (REST), and back them with Entity Framework and SQL Server, PostgreSQL. As a Full Stack Developer I pair those APIs with responsive front ends in Angular, React, or Blazor, then deploy and scale on Azure with Azure DevOps, Docker, and CI/CD. When a product needs AI, I wire proven models — often through a thin Python layer — into the application without breaking what already works. And when a templated WordPress or Shopify build has hit its ceiling, teams bring me in to rebuild it as a custom .NET web application that can actually grow. ✦ PROOF OF WORK Longevity is the point. I once took a rough idea from an automotive client and built it into an e-commerce platform that has served customers for nearly 15 years and still runs today. As the lead .NET Developer on Launch Control, a real-estate SaaS, I refactored the core and made the system 50x faster. I also built SiftScore, an AI-powered talent-acquisition platform that uses the OpenAI API to source and score large datasets. Across fintech, real-estate, and healthcare I've owned the full lifecycle as a Full Stack Developer: requirements, architecture, build, go-live. 🚀 SaaS MVP (From Idea → Production) When a client starts from a rough idea, I take it the full way: requirements, architecture, prototyping, build, and go-live on Azure. As a Full Stack Developer I've shipped .NET SaaS MVPs for fintech, real-estate, and conveyancing platforms — clean, maintainable code with the scalability and monitoring to grow once real customers arrive. ✦ AI Integration for Existing Products I add AI features when a product actually needs them. The fastest, most cost-efficient path is usually integrating a proven model — OpenAI, Claude, or Gemini, often through a thin Python layer — rather than training your own. I add chatbots, automation, and smart search to existing web apps. Most AI features fail not because of the model but because the surrounding .NET architecture wasn't built to support it — and that's where a senior Full Stack Developer earns their keep. ⚙️ Modernizing Existing .NET Systems - without the rewrite If you have a .NET or C# application that needs work, I optimize performance, refactor legacy code, upgrade aging ASP.NET back ends, and migrate data access to Entity Framework Core — refactored against SOLID principles, without freezing feature work. Stuck on an old ASP.NET WebForms app? You don't have to gamble on a big-bang rewrite. As a .NET Developer I migrated a WebForms spare-parts store — 20M+ products across 100+ suppliers — to ASP.NET MVC by running both side by side in one solution, so the business kept selling while the modernization happened underneath it. The same incremental approach moves teams off PHP, Laravel, or legacy WordPress builds and onto a maintainable .NET stack: ship value continuously, retire old code gradually, never go dark. ✦ Legacy .NET project modernization Old code isn't the enemy — downtime is. As a .NET Developer, I modernize legacy ASP.NET and ASP.NET MVC systems by introducing a clean API layer, migrating data access to Entity Framework Core, and refactoring against SOLID principles, all without freezing feature work. As a Full Stack Developer, I migrate the application page by page behind a feature flag, so new and old run together in production and you can switch any screen over — or roll it back instantly — without disrupting users. Whether it's an ASP.NET MVC application that has grown brittle or a WebForms system that needs a path forward, I find the route that lowers risk: incremental, tested, and reversible at every step. ✦ ENTERPRISE-GRADE .NET ARCHITECTURE My work as a Full Stack Developer goes deeper than features. On a large enterprise fintech platform built on microservices, as a Full Stack Developer I designed how the team builds — onboarding developers, setting architectural standards, and structuring a clean, maintainable .NET codebase that scales. As a .NET Developer with a decade across .NET Framework, .NET Core, ASP.NET, and ASP.NET MVC, plus an M.Sc. in Applied Mathematics behind the design decisions, means I build systems meant to last years, not quarters. I focus on web rather than native mobile apps in Flutter or React Native; on the .NET side I also ship cross-platform with .NET MAUI. I'm a web developer — my C# and .NET expertise powers web applications. ✦ HOW WE'LL WORK If you need a Full Stack Developer or .NET Developer who can take something from rough idea to production — and keep it running for years — let's talk about the fastest path to shipping it.

What does an ASP.NET Zero developer do?

An ASP.NET Zero developer builds line-of-business web applications by implementing custom features on top of the ASP.NET Zero starter solution. This role focuses on extending a production-ready foundation that adheres to SOLID principles across supported templates like ASP.NET Core MVC or Angular. The developer uses specialized tools to generate code layers from database definitions and manages the complex process of version upgrades.

  • The developer selects a project architecture, such as ASP.NET Core with Angular or ASP.NET MVC 5.x, and configures the initial environment. They use the ASP.NET Zero Power Tools Visual Studio extension or the dotnet CLI to process JSON input files. This action generates server-side entity layers, including data transfer objects, application service interfaces, and implementation classes. For Angular-based projects, the developer runs the Web.Host project and executes the nswag refresh.bat script to update client-side service proxies after generating new entities.
  • This professional defines custom templates within the Power Tools to control how the system produces code for specific business requirements. They create and modify authorization rules and permission sets as new entities and features enter the application. The workflow includes generating database migrations or updates to align the schema with the new entity definitions. This ensures that the generated CRUD layers match the intended data structure and security model without manual coding errors.
  • The developer maintains the health of the solution by executing documented branching and version upgrade processes. They review change logs to identify breaking changes or new features in the underlying framework. This work involves merging updates into the custom codebase while preserving existing business logic and configurations. The developer tests the upgraded solution to confirm that all generated components and custom modifications function correctly together.

How to hire an ASP.NET Zero developer on Upwork

Step 1: Post a job

Define your project architecture and feature requirements clearly to attract qualified candidates. Use the Job Post Generator powered by Uma™, Upwork's Mindful AI to draft a precise description. Describe your needs in a few sentences, and Uma creates a tailored post for this role. You can write a new post, update a saved draft, or reuse an existing post.

  • Specify the chosen template, such as ASP.NET Core MVC or ASP.NET Core with Angular, to ensure candidates possess the relevant frontend and backend skills.
  • List required experience with ASP.NET Zero Power Tools for generating entity layers, DTOs, and CRUD operations from database definitions.
  • Detail any necessary version upgrade tasks or custom authorization logic that the developer must implement within the SOLID foundation.

Step 2: Evaluate candidates

Review portfolios for evidence of complex line-of-business applications built on the ASP.NET Zero framework. Uma can run instant video interviews and build shortlists with side-by-side comparisons to help you assess technical fit quickly.

  • Look for GitHub repositories or case studies showing generated code structures, including app service interfaces and Angular components created via NSwag.
  • Verify experience with Entity Framework Core CLI and database migration scripts produced during entity generation workflows.
  • Check for demonstrated ability to handle solution upgrades using documented branching processes and change-log driven updates.

Step 3: Interview your top choices

Discuss specific technical challenges related to extending the base framework and managing permissions. Schedule and conduct interviews within Upwork Messages, which generates an immediate transcript and summary after each session.

  • Ask how they customize Power Tools templates to alter generated code output for specific business logic requirements.
  • Query their process for refreshing Angular service proxies using nswag refresh.bat after modifying server-side entities.
  • Explore their approach to implementing multi-tenancy features and role-based access control within the existing infrastructure.

Step 4: Agree on scope and begin work

Outline deliverables such as generated server-side layers, client-side UI files, and database updates. Use Upwork Messages and the contract workroom for communication and project management, plus identity verification, payment protection, hourly tracking, and project funds for security.

  • Define milestones for completing entity generation, implementing business logic, and testing CRUD flows in the selected architecture.
  • Set clear expectations for code quality, adherence to SOLID principles, and documentation of custom modifications.
  • Establish a protocol for handling version upgrades and merging changes from the main ASP.NET Zero repository into your solution.

Frequently asked questions

Is hiring an ASP.NET Zero developer worth it?

For most businesses, yes: hiring an ASP.NET Zero developer is worthwhile. This specialist builds line-of-business applications on a production-ready foundation rather than coding every feature from scratch. They use automated tools to generate entity layers and authorization rules, which reduces manual boilerplate work. You pay for their ability to extend the framework and manage version upgrades without breaking existing code.

How do I evaluate ASP.NET Zero developer candidates?

Evaluate candidates by asking them to describe their process for generating code with ASP.NET Zero Power Tools. A strong candidate explains how they define JSON inputs to create entities, DTOs, and app service interfaces automatically. Look for specific experience running NSwag refresh scripts to update Angular service proxies after backend changes. Verify they understand the branching strategy required for safe framework version upgrades.

What tasks does an ASP.NET Zero developer handle daily?

An ASP.NET Zero developer implements business logic on top of the starter solution using ASP.NET Core or MVC templates. They configure authorization permissions and maintain the codebase through documented version updates.

Which tools does an ASP.NET Zero developer use?

These developers rely on the ASP.NET Zero Power Tools extension within Visual Studio to generate CRUD layers from database definitions. They also use the dotnet CLI and Entity Framework Core CLI to execute code generation and manage database migrations.
