Luis L
About this gig
Looking to integrate OpenAI/LLMs into your product or build a real-time web dashboard?
I build fast, production-ready web applications and backend pipelines combining React, Next.js, Node.js, low-latency WebSockets, and AI APIs.
What I offer:
- AI and LLM Integrations: OpenAI API workflows, structured JSON outputs, streaming responses, automated data/log diagnostics, and custom assistants.
- Real-Time Dashboards: Live telemetry views, instant notifications, and real-time UI updates without page reloads via bidirectional WebSockets.
- Full-Stack Engineering: Clean TypeScript codebases built with React, Next.js, and Node.js/Express.
- Data Persistence: Integration with PostgreSQL, MySQL, MongoDB, or Redis.
What you receive:
- Maintainable, strongly typed code ready for production deployment.
- Secure environment variable setup (.env) with robust error handling.
- Direct communication in English and Spanish.
Message me before ordering so we can set the right scope!

FAQ
Do I need to provide my own OpenAI API key?
Yes. For final deployment you will use your own API key stored safely in a server-side .env file so you keep full ownership and billing control over your AI usage.
Can you integrate AI or WebSockets into my existing codebase?
Yes. Share your React, Next.js, or Node.js repository structure in chat and I will integrate the new pipeline cleanly without breaking existing routes.
Which databases can you connect to the web application?
I regularly integrate PostgreSQL, MySQL, MariaDB, MongoDB, and Redis for high-speed caching and real-time event pub/sub architectures.
