I build and fix mobile apps in Flutter and web apps & APIs in .NET — production software that businesses actually depend on. For the last 4 years my day job has been a Flutter app used every day by thousands of field crews across UK local government, so I'm used to the conditions real apps face: patchy signal, offline data, device hardware, real deadlines and code that can't fall over. What I can help with: • Flutter (iOS & Android) — new apps, features, bug fixes, refactors and upgrades • Firebase & Supabase — authentication, Firestore, storage • Offline-first sync and hardware integrations: GPS, camera, Bluetooth • Web apps & APIs in C#/.NET (ASP.NET Core, Blazor) with React front-ends • SQL / MSSQL design and optimisation, plus third-party API integrations • WordPress, WooCommerce and Shopify — fixes, customisations and maintenance 8+ years' experience, a First Class BSc in Software & Development, and recent professional certifications in advanced C#/.NET and application security. I'm a great fit for part-time, ongoing or project-based work — small builds, bug fixes and retainers. Tell me what you need and I'll give you an honest estimate and keep you updated throughout.

Ehtisham Zaki Senior .NET Architect & Full-Stack Developer ----- *Keywords: ASP.NET Core, C#, Blazor, Microservices, Azure, SQL Server, Web API, Angular, Docker, DevOps, Cloud Architecture, Enterprise Applications, Stripe Integration, PayPal API, Payment Processing, Third-Party APIs*

Senior C#, .NET .NET Core, ASP.NET, ASP.NET Core, WPF, React, AI Full Stack Developer I’m a Senior Full Stack Developer with more than 7 years of experience building reliable web applications using C#, .NET 8, .NET Core, ASP.NET Core, ASP.NET Web API, React, and TypeScript. C# and .NET are the technologies I work with most. I’ve spent years building backend systems, SaaS platforms, business applications, internal tools, and API-driven products with C#, .NET Core, and ASP.NET Core. A large part of my work involves building secure and scalable ASP.NET Core Web API applications. I use .NET 8 and C# to develop REST APIs, business logic, background services, authentication systems, third-party integrations, and real-time features. I’m also comfortable working across the full stack. On the frontend, I use React, Next.js, TypeScript, Tailwind CSS, and Blazor. I regularly connect React applications to ASP.NET Core Web API backends and handle everything from database design to deployment. I’ve worked on projects in healthcare, fintech, SaaS, and other data-focused industries. Some projects involved building new C# and .NET Core applications from the ground up, while others required improving existing ASP.NET Core systems, fixing performance issues, adding new Web API endpoints, or modernizing older software. I can help with: C# and .NET 8 application development .NET Core and ASP.NET Core backend development ASP.NET Core Web API design and development REST API and third-party API integrations Entity Framework Core and Dapper SQL Server and PostgreSQL development Authentication, authorization, JWT, and OAuth SignalR and real-time application features Hangfire and background processing React and TypeScript frontend development Full stack SaaS development Legacy .NET application modernization Azure and AWS deployment Docker, Kubernetes, and CI/CD pipelines Over the last two years, I’ve also focused heavily on AI and RAG development. I help companies add practical AI features to existing C#, .NET 8, .NET Core, and ASP.NET Core applications. This includes document search, internal knowledge assistants, AI chatbots, semantic search, automated workflows, and retrieval-augmented generation. I’ve worked with Azure OpenAI, the OpenAI API, embeddings, vector search, Azure AI Search, pgvector, Pinecone, Elasticsearch, and PostgreSQL. For example, I can build an AI-powered ASP.NET Core Web API that processes documents, stores embeddings, retrieves relevant information, and sends the right context to an LLM. I can then connect that service to a React or TypeScript frontend. My goal is always to build AI features that are useful in real products, not just impressive demos. I also help clients modernize older .NET applications. That may involve moving from .NET Framework to .NET Core, upgrading an existing system to .NET 8, replacing an outdated ASP.NET application with ASP.NET Core, improving old Web API services, or rebuilding a WinForms or WPF application as a modern web platform. I understand that legacy systems often support important business operations, so I approach modernization carefully. I focus on improving the system without creating unnecessary risk or disrupting existing users. When building new systems, I care about clean architecture, readable C# code, sensible database design, clear API contracts, and maintainable frontend components. I don’t believe in making software more complicated than it needs to be. I prefer practical solutions that are easy to understand, test, maintain, and extend. My main technical stack includes: C#, .NET 8, .NET Core, ASP.NET Core, ASP.NET Core Web API, Entity Framework Core, Dapper, LINQ, SignalR, Hangfire, FluentValidation, SQL Server, PostgreSQL, Redis, Elasticsearch, React, Next.js, TypeScript, JavaScript, Tailwind CSS, Blazor, Azure, AWS, Docker, Kubernetes, Azure DevOps, GitHub Actions, xUnit, Serilog, and Seq. Clients usually value my clear communication, realistic estimates, and ability to take ownership of a feature from start to finish. I’m comfortable joining an existing C# and .NET team, maintaining a large .NET Core codebase, building a new .NET 8 application, developing an ASP.NET Core Web API, or handling a complete React and .NET full stack project. If you’re looking for a dependable C# developer with strong experience in .NET 8, .NET Core, ASP.NET Core, Web API, React, and AI integration, I’d be happy to learn more about your project.

I build and improve custom .NET web applications, dashboards, internal tools, admin panels, and client portals using ASP.NET Core, Blazor, React, APIs, and clean backend logic. I can join an existing .NET project, understand the current codebase, fix issues, add new features, improve the frontend/backend, and support the product long-term. My clients typically need one of two things: 1. A new web application, dashboard, admin panel, or client portal built from scratch. 2. A reliable developer to take over and evolve an existing system without breaking what's already working. HOW I HELP: ✅ Build custom .NET web applications for business workflows ✅ Develop dashboards, admin panels, internal tools, and client portals ✅ Improve existing ASP.NET Core / Blazor / React applications ✅ Add new features, fix bugs, and support long-term product development ✅ Integrate APIs, databases, authentication, user roles, and third-party tools ✅ Help businesses replace manual processes with clear, stable, scalable web systems PROBLEMS I SOLVE: ⚠️ Outdated or unstable web applications ⚠️ Internal processes still running on spreadsheets or manual work ⚠️ Existing .NET projects that need bug fixes, new features, or ongoing support ⚠️ Dashboards or admin panels that are hard to use or maintain ⚠️ Business tools that don't scale as the company grows ⚠️ No reliable developer who can understand the codebase and support it long-term WHAT MAKES ME DIFFERENT: Most freelance developers can write code. Fewer can be trusted with an existing, live system. I focus on: ✅ Clean, maintainable backend logic — not quick fixes that create bigger problems later ✅ Understanding the full workflow before building a feature ✅ Clear communication throughout the project ✅ Staying engaged after delivery, not disappearing once the invoice is paid WHAT YOU GET: I build and improve custom .NET web applications designed around your business workflow, not just around a list of technologies. That can mean building a new application from scratch, improving an existing ASP.NET Core / Blazor project, creating a dashboard or admin panel, connecting APIs, fixing bugs, adding features, or providing long-term support. 🎁 INCLUDED WITH EVERY PROJECT: ✅ A high-level review of your current workflow or application structure, with suggestions for improving stability, usability, or maintainability ✅ Suggestions on simplifying features before development starts ✅ A clear breakdown of what to build first, if your project has multiple stages GUARANTEE: If the final result doesn't match the agreed brief, scope, and quality standards, I'll revise it within that same scope until it meets the requirements. MY WORKFLOW: Not sure how to describe the technical task yet? I'll help you structure it. Send me your idea, existing app, requirements, user flow, business process, Figma design, bug list, API docs, or current codebase, and I'll help define the right approach. MY PROCESS: 1. Discovery & requirement review 2. Workflow / codebase understanding 3. Technical planning 4. .NET / ASP.NET Core / Blazor / React development 5. API, database & backend logic implementation 6. Testing, bug fixing & improvements 7. Revisions & final delivery Click the message button, send me your idea, existing app, or technical task, and I'll help you define the next step.
