Hire the Best Angular Developers
in the United States

I'm a full-stack .NET developer with 11 years of experience based in Los Angeles. I'm a true full-stack developer, so I can work equally well on both front and back ends. I have experience in building applications from start to end, so I can take care of building almost any project, then supporting it for the long term. Here are some highlights from my background: - My tech stack is .NET, .NET Core, C#, SQL, Entity Framework, HTML, CSS, JavaScript, and Angular. - Experience with Azure and AWS. I'm especially good with Azure. I can setup Azure resources such as App Services, Function Apps, Azure SQL Databases, Storage Accounts, Key Vaults, Azure DevOps source control, deployment pipelines, etc. - Experience in working on large SaaS applications in healthcare, manufacturing, retail, human resources, and legal industries. - Experience in developing MVPs from start to end. - I write clean and understandable code with well defined architecture using best practices for software security. - Experience in SaaS and multi-tenant applications. - Great work ethics and honesty. If I don't know something, I'll tell you. If I messed up something, I'll tell you. My Certifications: - Microsoft Certified: Azure Developer Associate - Microsoft Certified: Azure AI Engineer Associate Also, I have a team of full-stack software developers. Building and supporting an application for a successful startup usually requires more than one developer. Building an application is like building a house. It usually requires a crew to complete. My team can join your project and help with building it, then support and enhance it in the future.

I help businesses fix, modernize, and scale their Angular apps. With 10+ years as a full-stack developer, I know how to quickly diagnose tough issues, untangle messy code, and upgrade Angular projects to the latest best practices. ✅ Need bug fixes or performance improvements? I can spot problems fast and deliver clean solutions. ✅ Stuck on an old version of Angular? I’ll modernize your app and bring it up to date. ✅ Starting fresh? I build responsive, user-friendly apps with Angular, Vue/Quasar, and reliable back-ends in Node.js/TypeScript or .NET. I also handle the full pipeline: secure APIs, AWS cloud hosting (EC2, Lambda, DynamoDB, S3, API Gateway), and CI/CD so your app is stable and scalable. Clients choose me because I fix problems quickly, communicate clearly, and deliver results that last. For samples of my work, please visit my GitHub profile.
