I will add AI features to your app with OpenAI or Claude, or build your backend API

I build backends, APIs, and AI-powered features for web and mobile products.

What I can do:
- Integrate the OpenAI and Anthropic Claude APIs into your product: chat assistants, content generation, summarization, structured data extraction, and AI workflows
- Design and build REST or GraphQL APIs in Node.js / Express
- Real-time features with WebSockets (chat, live updates)
- Database design and migrations in PostgreSQL or MongoDB
- Authentication and permissions (JWT, OAuth 2.0, role-based access)
- Docker, CI/CD, and deployment on AWS
- Fix, refactor, or modernize an existing codebase

About me: 8+ years as a full-stack engineer. At Venue I lead AI feature integration with the OpenAI and Claude APIs and re-architected the Express/MongoDB backend. I've also built APIs and microservices for enterprise projects with Hewlett Packard Enterprise and Verizon.

Send me what you need and I'll reply with an approach and estimate.
