Mobile apps rarely fail at launch. They fail when they scale, break, or stop delivering value to users. ***That is where the real work begins*** I work with startups and businesses to build mobile applications that are not just launched, but are stable, scalable, and built to perform under real user demand. From idea to App Store and Google Play, the focus stays on reliability, speed, and long-term usability.

Top Rated Plus (Top 1% on Upwork) | 100% Job Success | 3,800+ Hours Billed | HIPAA & Privacy Law Certified (UPenn) Most of my work over the past 10 years has been backend systems where failure gets expensive. A payroll platform that pays US businesses on time, every cycle. An EHR holding patient records for two healthcare organizations in Florida. A B2B platform a Silicon Valley startup runs its sales intelligence on. All shipped, all live, all still running without me babysitting them. That last part matters. As a Full-Stack Developer, I build systems that hand off cleanly: documented APIs, CI/CD pipelines on Azure, databases another developer can read in a week. You own the code, and you can run it without me. What I actually do as a Backend Developer: REST APIs and services in ASP.NET Core, C#, and Python (FastAPI, Django). Database design in PostgreSQL, MySQL, and SQL Server. Microservices and multi-tenant SaaS architecture. On the frontend, React and TypeScript. For mobile, Flutter apps live on the App Store and Play Store, including one with 500K+ downloads. HIPAA work is a specialty, and I'm certified: Privacy Law & HIPAA through the University of Pennsylvania. I've built EHR/EMR systems, EVV home care platforms, and hospital task management tools. If your product touches patient data, I already know what an audit looks for: encryption at rest, access logging, role-based permissions. I also do AI Development inside real products. LLM features, automation, and agentic workflows using Claude and OpenAI APIs. I use Claude Code and Cursor daily, so AI-assisted delivery speed comes standard. Clients typically hire me as a Full-Stack Developer or Backend Developer for: SaaS platforms and API-driven web applications HIPAA-compliant healthcare software Fintech and payroll systems with third-party integrations Flutter Mobile App Development, backend included Rescuing or scaling an existing ASP.NET Core / React codebase Every project comes with 45 days of free maintenance after launch, and larger builds get extra specialist hands under my lead when the scope calls for it. My longest Upwork contract ran 1,739 hours with the same client. That's the kind of working relationship I build. If you want a second opinion on your architecture or a straight read on scope and timeline, message me. Worst case, you walk away with a clearer plan.

Expert in full-stack web application development, Azure Bot Framework, Microsoft Teams apps, legacy application modernization, and long-term product support using ASP.NET Core, C#, Blazor, MVC, Web API, React, Angular, and modern cloud technologies. 𝐋𝐨𝐨𝐤𝐢𝐧𝐠 𝐟𝐨𝐫 𝐦𝐨𝐫𝐞 𝐭𝐡𝐚𝐧 𝐣𝐮𝐬𝐭 𝐚 𝐝𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫? Hi, I'm Arslan Zafar—a Senior Full Stack .NET Developer focused on building secure, scalable, and high-performance applications that solve real business problems. With 8+ years of experience, including work with organizations like TCS, T-Mobile, and CBA, I bridge the gap between complex business requirements and clean, scalable technical solutions. ASP.NET MVC and legacy modernization Some of my most complex ASP.NET MVC work has been in defence and industrial sectors. I modernized a legacy web platform for a company managing high-uptime naval fleet assets — warships that cannot afford downtime. The ASP.NET MVC rebuild enabled accurate asset tracking, secure document storage, and streamlined access to sensitive operational data. On another engagement I took over a large workplace management SaaS system that a single developer had left behind — no documentation, daily hotfixes, frequent outages. I stabilized the ASP.NET Core back-end, eliminated the performance bottlenecks, and established proper development processes from scratch. ASP.NET Zero and enterprise acceleration ASP.NET Zero is my go-to when enterprise clients need multi-tenancy, role-based permissions, and audit logging without spending the first three sprints on boilerplate. I have used it to accelerate delivery on projects in pharma automation, workplace management software, and industrial IoT — cutting setup time significantly and letting the team focus on actual business logic from day one. Full-stack development across the whole system Full-stack development for me means owning the entire delivery — ASP.NET Core back-end, Angular or React front-end, Microsoft SQL Server database design, and Azure infrastructure. I built a Shopify fulfillment tool in ASP.NET Core and React that reduced packing mistakes to zero for e-commerce teams — integrating barcode scanning, inventory management, and connections to 8+ shipping providers. I have also delivered a fleet management system in .NET 9 and Angular handling large industrial equipment rental, tracking, and reporting at scale. On the front end I work with Angular, AngularJS, React, TypeScript, JavaScript, and Bootstrap — and I connect them cleanly to ASP.NET back-ends without creating maintenance nightmares six months later.🚀 Microsoft Certified Azure Administrator | 13+ Years | Enterprise SaaS Architect What I can help you with: ✅ ASP.NET Core, C#, .NET 8, Web API, and backend development ✅ React, Angular, Blazor, TypeScript, and full-stack web applications ✅ SaaS platforms, admin panels, dashboards, and enterprise business systems ✅ Legacy .NET Framework / ASP.NET MVC modernization ✅ SQL Server, EF Core, database design, reporting, and performance tuning ✅ Azure App Services, Azure Functions, Azure Service Bus, Azure SQL, and Key Vault ✅ Microservices, clean architecture, CQRS, background jobs, and distributed systems ✅ API integrations with Xero, QuickBooks, Zoho Books, Stripe, PayPal, Twilio, and third-party platforms ✅ AI integrations using OpenAI, automation workflows, OCR, and intelligent business tools ✅ WinForms, WPF, desktop applications, printer SDKs, RFID, barcode, and hardware integrations ✅ CI/CD pipelines, GitHub Actions, Azure DevOps, Docker, deployment, and production support Keywords Senior .NET Developer Upwork Full-Stack .NET Developer Upwork ASP.NET Core Developer Upwork ASP.NET MVC Developer Upwork C# Developer Upwork .NET Core Developer Upwork .NET Backend Developer Upwork .NET API Developer Upwork REST API Developer Upwork Microservices Developer Upwork Enterprise Application Developer Upwork SaaS Application Developer Upwork Cloud Application Developer Upwork Azure .NET Developer Upwork SQL Server Developer Upwork Database Architecture Specialist Upwork Performance Optimization Specialist Upwork Software Maintenance & Support Upwork Application Migration & Upgrade Services Upwork Third-Party Integration Specialist Upwork Core Skills ASP.NET Core, .NET Framework, C#, .NET Core, MVC, Web API, Entity Framework Core, SQL Server, Azure SQL, Microservices, RESTful APIs, SignalR, Blazor, Azure, AWS, Docker, CI/CD Pipelines, Agile Development, Responsive Web Design, Frontend Development, Backend Development, Database Management, Scalable Architecture, Cloud Deployment.Senior .NET Developer, Full Stack .NET Developer, ASP.NET Core Developer, C# Developer, .NET Core Developer, REST API Developer, Microservices Developer, Azure .NET Developer, React Developer, Angular Developer, Blazor Developer, SQL Server Developer, SaaS Developer, Enterprise Application Developer, Legacy Modernization, API Integration, AI Integration, OpenAI API, Entity Fra
