I will build nodejs backend with API and ai integration openai or claude


About this gig
Need a Node.js backend that just works and doesn't fall apart
when you plug in AI?
I build fast, secure backend systems and REST APIs, and I
specialize in connecting them to AI services like OpenAI and
Claude. Whether you're building a SaaS product, an AI-powered
app, or need to integrate a third-party API into your existing
platform, I handle the backend engineering so you can focus on
your product.
WHAT I CAN BUILD FOR YOU:
- Custom REST APIs with Node.js and Express
- OpenAI / Claude / LLM integrations (chatbots, content
- generation, AI features)
- Third-party API integrations (Stripe, Twilio, webhooks, etc.)
- Database design and setup (MongoDB, PostgreSQL, MySQL)
- Authentication systems (JWT, OAuth)
- Bug fixes and performance optimization on existing Node.js
- backends
- API documentation so your team can maintain it long-term
WHY WORK WITH ME:
- Clean, documented, maintainable code not just "it works"
- Clear communication throughout the project
- Security-conscious backend design (proper auth, input
- validation, error handling)
- I explain what I built, not just hand over a black box
