Senior Developer (Angular / .NET, AI-first workflow)

We build enterprise SaaS. We want AI embedded in the way code is written, tested, and secured. A daily practice, not a backup. Start with one short paid task. If it goes well, ongoing long-term work. You will: 1. Build features in Angular and/or .NET/C# 2. Build and maintain mobile apps in React Native 3. Use AI coding tools (Claude, Cursor) as your default workflow 4. Write secure, clean code and flag risks early You have: 1. 10+ years of hands-on development 2. Strong Angular or .NET/C#, plus React and TypeScript 3. Strong mobile app development with React Native 4. Demonstrable AI in your daily workflow (we'll ask you to show us) A plus, not required: 1. Azure Notes: Keep all communication in Upwork. Off-platform contact won't be answered. This is an independent contractor engagement. Apply with one example of how you've used AI in real development work. Skip generic proposals.
